Detailed Explanation of Electroplating Zinc-Nickel Process Flow
Author:Robby
Electroplating zinc and nickel is a surface treatment process of electroplating zinc and nickel at the same time, different from electroplating zinc and nickel respectively.
First, the process of electroplating zinc and nickel
Zinc-nickel plating is a process of plating zinc and nickel on the surface of the substrate at the same time. The process flow is as follows:
1. Substrate surface treatment: first of all, the surface of the substrate needs to be treated to ensure that the plated layer can be firmly attached to the substrate surface after plating. Surface treatment usually includes degreasing, pickling, washing, etc. 2.
2. Pre-plating treatment: Before plating, the substrate needs to be treated so that it can better contact with the plating solution. The treatment usually includes steps such as activation and catalysis.
3. Electroplating: The treated substrate is immersed into the electroplating bath, and through electrolysis, zinc and nickel are deposited simultaneously on the surface of the substrate to form a zinc-nickel alloy coating. The composition of the plating solution and the process conditions affect the performance and quality of the alloy coating. 4.
4. Post-treatment: Cooling, washing, drying and other steps are required after plating to ensure that the alloy coating can fully adhere to the surface of the substrate.
Second, the difference between electroplated zinc-nickel and separate plating
What is the difference between electroplating zinc and nickel and electroplating zinc and nickel separately? Zinc-nickel plating is a surface treatment process that plates zinc and nickel at the same time, while separate plating of zinc and nickel is the first zinc plating, then nickel plating. Since zinc-nickel plating can form a zinc-nickel alloy coating on the surface of the substrate at the same time, it is more efficient than the process of electroplating zinc and nickel separately, and the alloy coating has better performance.
Third, the application of electroplated zinc-nickel
Zinc-nickel plating has good corrosion resistance, wear resistance and heat resistance, so it is widely used in automotive, aviation, aerospace, electronics, machinery and other fields. For example, in the automotive industry, zinc-nickel plating is used as a surface treatment for car bodies and parts to improve their corrosion and wear resistance.
In short, zinc-nickel electroplating is an efficient and high-quality surface treatment process with a wide range of processes and applications. Understanding the process and characteristics of electroplated zinc-nickel can help us better use and maintain electroplated zinc-nickel treated items.
