Alkaline zinc plating is a widely used electroplating process that deposits a layer of zinc onto a metal substrate (typically steel or iron) in an alkaline (high pH) electrolyte solution. The primary purpose of this zinc coating is to provide excellent corrosion protection to the underlying metal, and it is available in Blue, Bright, Yellow, and Black finishes.
Provides a uniform zinc deposit on parts with complex geometries, including recessed areas and blind holes.
Offers sacrificial protection to the underlying steel or iron, significantly extending the part's lifespan by corroding before the base metal.
Modern alkaline zinc plating systems are non-cyanide, making them more environmentally friendly and simplifying waste treatment.
The plating process has a lower risk of causing hydrogen embrittlement compared to other plating methods, which is crucial for high strength steel components.
The zinc coating is ductile and less prone to cracking or peeling, making it suitable for parts that will be bent or formed after plating.
