A salt spray chamber is a useful piece of machinery to evaluate how well a substance or coating holds up against corrosion. The instrument is often used in paint and plating testing to determine the extent to which coated samples are resistant to corrosion or rust. The method is called salt spray testing.
The equipment is used to evaluate materials that have a metallic surface coating. This test effectively uses a corrosive attack on coated samples to determine the coating&#;s suitability as a protective finish. The time frame in which rust byproducts are evaluated is fixed in advance.
Applications
Different applications call for testing the rust resistance of coated test specimens in a salt spray chamber YWX/Q-010. Automakers use the coating extensively because of its exceptional corrosion resistance to ferrous alloys.
Aerospace: Airplanes, helicopters, space shuttles, and other vessels used in aerospace are subjected to harsh circumstances. These conditions may vary from temperature variations to a vacuum state in outer space.
To evaluate the corrosion resistance of the metallic components of aircraft parts and assemblies, the test chambers are well suited for use in the aerospace industry.
Automotive: Because of the consistent demand, producers and suppliers of automotive components and parts are now grappling with a significant obstacle in improving the overall quality of their wares. It is a serious problem whether it can preserve the quality of vehicle components despite the severe weather conditions.
The test chambers provide an effective testing technique that ensures the end consumers will have a pleasant and risk-free experience while using the device. It must always perform corrosion tests on automobile components; failing to do so puts the whole vehicle at risk of deterioration.
Electronic Components: To avoid potentially hazardous conditions, electrical components must be of high quality and robustness. In an area with a high salt concentration, it is essential to test the rust resistance of any metallic electrical equipment or wiring.
Paint & Coating Test: The salt spray chamber YWX/Q-010 is used to test the rust-proofing capabilities of paints and coatings and anticipate the materials&#; corrosion resistance. In this test, coatings and paints were exposed to corrosive conditions and measured their resistance.
Hardware Tools: Rust is a destructive force it may find on tools. It should not use rusted instruments since they pose a safety risk and have the potential to inflict significant harm.
Medical Equipment: Since the health of a human is closely tied to the use of medical equipment, it must be trustworthy and long-lasting. The salt spray testing will have to be used to determine how resistant to corrosion this apparatus is. It is unacceptable to allow corrosion to occur on medical equipment.
Railway: The corrosion resistance of railway components, rails, and other equipment must be checked. The term &#;corrosion&#; refers to the weakening or deterioration of the metallic surface, and salt spray testing provides circumstances like corrosion to evaluate the resistance of the materials to rust.
Advantages and Features of Salt Spray Chamber
1) The salt spray test is performed on various materials since it\ may carry it out on naked and printed materials.
2) The length of the exam is brief when measured against the natural environment. The material must be standardized and keep the price to a minimum.
3) Additionally, a combined test of the material and the surface polish is provided by the chamber. It might evaluate the formed things and fitted components, and the testing outcomes are straightforward to comprehend.
4) The testing equipment offers the precision as well as the flexibility that is necessary to satisfy the rigorous corrosion test procedures of today.
5) Within the salt spray chamber YWX/Q-010, the machine can produce a salt spray in an environment with a high humidity level and air drying at a certain temperature.
6) There is the potential for the corrosion cycle to be repeated an infinite number of times automatically.
The maritime and automotive sectors and any other business whose wares will be utilized mostly outside or must fulfill a mechanical load-bearing function need salt spray testing the most.
The performance of mobile devices, such as cell phones and tablets, must be equally reliable in humid and dry environments for the electronic manufacturing industry to succeed.
The Importance of Salt Spray Testing
Corrosion has far-reaching consequences that extend well beyond the aesthetics of rust, and it doesn&#;t take much proof to recognize that.
Northern drivers have a strong appreciation for corrosion-resistant materials. In particular, the undercarriage of automobiles considered &#;beaters&#; or &#;clunkers&#; are susceptible to damage from the salt that accumulates on winter roads. When a vehicle is corroded, it endangers not just the driver but also everyone else on the road.
In the same way that automakers invest time and money into studying and perfecting corrosion-resistant components, governments also invest time and money into improving the roads&#; quality.
Salt and water may eat away at asphalt and concrete underneath the surface. Researchers are working on remedies, such as water- and salt-resistant pavement.
That&#;s why salt spray testing is very necessary to avoid these kinds of trouble.

Q. I want to design and manufacture a Salt Spray Apparatus. However, I would like to know all the components needed to make the best test cabinet on the market. This will enable my company to serve the needs of all who are in need of the perfect cabinet.
Your help will be greatly appreciated.

A. Hi, Mike.
I'd start by examining the newest salt spray cabinets from the existing suppliers and see in what ways, if any, they seem deficient to you. Then I would do a patent search because there are certain accessories or approaches you are prohibited from offering. Then I would check the ASTM corrosion tests to see what kind of specifications the cabinets you wish to design must meet.
I think you'll find letter interesting as the inquirer asked what factors are important in choosing a salt fog cabinet and several readers offered their answers. Good luck!

A. First of all, take a look at what is already commercially available. There are a few major companies that already do very well in this market. You will have to have some sort of advantage over existing cabinets to convince people to buy from you. If you are not already intimately familiar with salt spray testing, I don't see how you could compete.
The cabinet must fully comply with ASTM B117. Good cabinets will also have the capability to run humidity testing, CASS testing, and perhaps even Kesternich testing. A top-of-the-line chamber must have controllable temperature, fog rates, and relative humidity. It should be able to do cyclic tests and be programmable for custom cyclic testing.
Make sure you understand what you are getting into before you invest a lot of money, time, and effort.
Good luck!

Q. I am looking to make a simple one time use salt spray cabinet to test circuit boards for corrosion. Kind of DIY project. The cabinet doesn't have to meet any standards or be commercial quality. Any ideas where to start besides ASTM B117. What simple household materials can I use (eg. hose nozzles). Anything will help.
Thanks,
Ilya Frishman
- Milwaukee, Wisconsin, USA
A. Hi, Ilya. If you just wish to accelerate the corrosion, with no standards to meet, just pour wet salt on the boards, leave them in the sun, and spritz when they get dry.
But if you seek repeatability, yet don't wish to buy a salt fog chamber, you might do a search for "CAMRI testing". This is a highly repeatable accelerated corrosion test that can be done with very little investment, and has been used by very reputable organizations including the International Zinc Association. Good luck.

A. Attached is a pic of a DIY chamber I built to test supplier hardware used on high end high performance windows and doors. Like most of your responders suggested I went to ASTM B117 to put together requirements for establishing the design intent.
Much of these products I test are used on or close to ocean front environment. Also I test samples from in-house painting and vinyl film laminating.
This unit which we invested about $500.00 has been operating about 6 months. In that time it has paid for itself about 10-fold. I can give details if requested.
Most suppliers I deal with are eager to make changes to correct issues I have found in their products.
I would be happy to share details of design and parts used.

Q. I want to perform a salt spray test on diodes which has salt concentration 5% and duration will be of 48 hrs. Can anyone please suggest me how should I proceed if I want to make this salt spray chamber within range of specified conditions above so that I can also conduct similar tests in future? I am basically interested in developing chamber by myself. :)
Abhay Thakur
- Mumbai, India
A. Hi Abhay. I would start by obtaining a copy of ASTM B117 or ISO since I'd assume that you would want the results of your 5% salt spray test to be similar to the results that others get when they conduct 5% salt spray tests, and you'll want to know what you have to do for your results to have validity in that regard.
After that, you might follow Tom West's explicit directions, or ask highly specific questions about them. Good luck.

Q. Hello,
I have to do both ASTM B117 and ASTM G85 A5 tests for my PhD project and, considering the cost for a prohesion testing chamber, it seems more reasonable to acquire a used salt spray chamber and apply some modifications to make it capable of cyclic tests (i.e., G85 A5).
According to G85 A5, fog in the cabinet should be removed in 1 hour sequences. Do you have any recommendations for the pump or fan to suck this highly corrosive fog out of the chamber?

Q. Hi, I am an electrical engineering student working with an electrical company. My task is to build a salt fog box. I have a good understanding on how to do this thanks to extended amounts of online reading.
I do though have a few questions that I just couldn't find a proper answer for. I struggle to find information on pumps ... can I use any water pump to pump the salt solution to the atomizing nozzles? What is the simplest way of doing this? Also any information that can be shared on this project will be much appreciated. Thank you.

A. Hi Andrew,
In general, the salt solution goes by gravity to a middle tank (this tank with a floating valve) with the same level as an inner tank, this with the nozzle. This system is feed with water-saturated air, and it sucks (by venturi effect) the water from the inner tank into the nozzle and therefore into the chamber.
There are many schematics of this, but every nozzle I have seen for this type of chambers works the way I described.
Hope it helps!

Q. Hi Daniel,
thanks for your response. I don't really understand your answer ... can you link me a schematic showing me your method? In a sense all I need to do is create a venturi effect to suck water into the nozzle?
Thanks Andrew

Hi Andrew!
I was sure that what I was trying to explain was very complex to say with words only.
I drew a very schematic view of my chamber, so you can see how it works...
Saturated air is injected into an ejector, which sucks the salt water into the chamber. This ejector has this shape (I tried to draw it as I remember it, as I can't take it from the chamber without interrupting all our assays) that allows liquid to go up because of the low pressure in the upper part, and you can make the volume of this chamber (between the cap and the cone) higher or lower by screwing or unscrewing the cap, this makes bigger or smaller drops in the ejected spray.
Hope this helps you in your project! Best of luck!

Q. Hi,
First I must say, good job and thanks for sharing.
I have several questions: Do you put pressure cooker on the single burner hot plate? Is the silicone pad heater warming the chamber? Is the chamber isolated well enough?
Thank you for your answers.
Nejc Novak
Faculty of Mechanical Engineering - Ljubljana, Slovenia
A. Hi Nejc,
I don't fully understand your questions, because we don't have any burners in our chamber, and I don't know any gas fueled salt spray chamber. So, I will answer the things I understood of your questions:
1- The chamber is warmed by two ways:
a) The saturated air is at 40 °C when it enters the ejector. It cools a little when it comes out the ejector, but heat enters the chamber anyway.
b) There is another chamber full of deionized water under the salt spray chamber. This chamber is heated by an electric heater with a thermostat. It heats up to 60 °C this chamber, and by contact it warms the chamber to a comfortable 35 °C. Keeping some salt water at the bottom of the salt spray chamber keeps it regulated well enough between 34.5-35.5 °C.
2- The chamber is not well isolated, It's only plastic. It doesn't have to be very isolated to allow over-temperature to wear off when it comes to that, and you only need a small heater to keep it working day and night at optimal temperature.
Hope it helps!
