Electrolytic corrosion of cadmium plated steel and cast iron items in order to protect from is widely applied in industry. Usually 10 to 20 microns thickness of a coating to protect metal from corrosion in the main outdoor weather conditions is sufficient.
The Advantages Of Cadmium Plating:
→Cadmium, zinc compared to more ductile it is. Therefore, cadmium coated parts can be bent easily or can be formed. However, zinc-coated parts during bending or shaping of cracks in the coating consists of.
→Solder coated surfaces cadmium, zinc coated surfaces is easier than. In terms of ease of soldering really cadmium coated surface with tin coated surface is almost the same. Electrical conductivity of cadmium, tin is higher than. Although the electrical conductivity of zinc with tin is slightly higher initially, surface surface during the passage of the electric current, cadmium much easier than the surface of dark (white oxide consists of higher) becomes resistant. As a result of this fast sitlenme arrow, and therefore the high conductivity of the zinc surface will fall initially junction points cadmium coated, zinc-coated will be superior to the one.
→In the open air in terms of avoid rusting of iron and steel, cadmium or tin for most applications and provides better results compared to better, from this perspective, cadmium plating, zinc plating has with equal performance. Below, this difference in properties of cadmium electroplating protection against corrosion (electrochemical properties will be explained in the section.
→The lubricating property of the surface of coated with cadmium, zinc coated belongs because is better than it was. What this means, cadmium coated with gear pieces to freeze and boil together is a very rare event.
