Mostly it is seen that special surface treatment is required for metal surfaces, in order to have the desired optimum properties. The coating method differs for different applications. We at Unispares India have the following surface coating techniques:
- Blue – Blue Zinc is also called clear passivate or silver zinc. Blue chromates provide 48 hours of protection against white corrosion.
- Yellow – Yellow Zinc Plating refers to the color of the chromate that is applied after zinc gets deposited on the surface. Yellow Chromate actually protects from corroding.
- Black – Black zinc plating is the color chromate that is applied after the plating process. It includes a layer of zinc on the surface by black chromate.
The ability of the chromate layer to protect zinc from corrosion is strongly dependent on the thickness of the passivating layer. Cr (VI) is developed for zinc iron. It helps in surface strength and meets the higher automotive industry corrosion standards. Hence, Unispares India uses it for spare parts and components of the automobile industry
