What Is Involved in Zinc-Nickel Plating?

Zinc alloy plating refers to the use of electroplating to obtain different zinc alloy plating layers to achieve a certain purpose.

Zinc-nickel alloy
The so-called zinc alloy refers to zinc as the main metal in the electroplating alloy, and its content should be more than 51% (mass percentage). In addition, it contains one or more other metals. For example: zinc-nickel alloy (containing about 10% nickel), zinc-iron alloy (divided into high-iron alloy and low-iron alloy, the former mass percentage is more than 7%, while the latter is <1%), zinc-copper alloy (commonly known as white copper, copper mass percentage 15% to 25%).
The said alloy plating refers to the use of electroplating to obtain different zinc alloy coatings to achieve a certain purpose.
When one or several other small amounts of metal elements are introduced into the zinc coating, its performance is greatly improved compared to pure zinc coating. For example: zinc-nickel alloy coating (containing about 10% nickel) has higher corrosion resistance than the zinc coating alone. It is widely used to replace the toxic cadmium coating. The introduction of <1% (mass) iron or diamond metal in the coating may increase the corrosion resistance by more than three times. In addition, the zinc alloy coating also has excellent thermal stability and low hydrogen embrittlement.
