Electroless nickel is an electrochemical deposition technology that reduces nickel ions to water-insoluble metallic nickel and deposits it on the surface to be plated, thereby forming a protective nickel layer. This coating is widely used on steel, copper, aluminum and other materials.

I. Overview of the hardness of electroless nickel
Electroless nickel is an electrochemical deposition technology that reduces nickel ions to water-insoluble metallic nickel and deposits it on the surface to be plated, thereby forming a protective nickel layer. This coating is widely used on steel, copper, aluminum and other materials. Surface coatings have many advantages, the most notable of which is their high hardness.
II. Testing method for electroless nickel hardness
Testing of electroless nickel hardness requires the Vickers hardness test, which is a widely used hardness testing method. The Vickers diamond indenter used in the test is capable of withstanding different loads, which are gradually increased during the test. During the test, the indenter will make a small mark on the prepared metal surface. The material hardness around the test point can be quantified by the size of the impression around the test point.
III. Hardness range of electroless nickel
The hardness of electroless nickel is generally between 550-650HV, but may vary under different circumstances. The hardness of the coating can be adjusted as required to suit different applications. In addition to its hardness, electroless nickel also has excellent corrosion and wear resistance, which can extend the life of the metal.
IV. Application of electroless nickel
The advantage of electroless nickel is that it provides a high-quality protective coating to resist corrosion and wear. Electroless nickel plating can also improve the lubricity of the material surface, reduce friction and wear, thereby increasing the service life of the machine or equipment. Electroless nickel plating can be used in many different areas, such as automotive manufacturing, aerospace, electronics and machine manufacturing.
IV. in conclusion
Electroless nickel is a superior protective coating with a wide range of applications in corrosion, wear protection and surface lubrication. The hardness of electroless nickel is generally between 550-650HV, and the coating can be adjusted to suit different applications.
