Material requirements for plating
The coatings are mostly single metals or alloys, such as titanium palladium, zinc, cadmium, gold or brass, bronze, etc . there are also diffusion layers, such as nickel-silicon carbide, nickel-fluorinated graphite, etc . and coatings, such as steel Copper-nickel-chromium layer, silver-indium layer on steel, etc. In addition to iron-based cast iron, steel, and stainless steel, electroplated substrate materials also include non-ferrous metals, or ABS plastic, polypropylene, polysulfone, and phenolic plastics. However, plastics must undergo special activation and sensitization treatments before plating.
