Zinc plating. Zinc plating is a common surface treatment which is mainly used on light springs as it works together with supplementary treatment of Cr+3 chromates or other sealers to form a good protection against corrosion. There is a risk of hydrogen embrittlement and hydrogen reduction by heating but it is necessary for completing the plating.

Zinc also provides outstanding metal distribution and uniform covering power. The coating is capable of accepting the environmentally friendly clear blue trivalent chromium passivate as well as yellow and olive drab finishes. Wear Protection: Zinc plating bestows an increased surface hardness on the item with the finished hardness (100g HV)

Surface Treatments For Disc Springs. Mechanical Zinc Plating. A mechanical plating process that allows a substantial thickness of zinc to be applied to the surface of the disc spring without the risk of hydrogen embrittlement associated with normal electroplating. A passivation would then be applied to seal the plating.

  • Understanding Clear Zinc Plating

    Is the zinc truly clear? Clear zinc plating essentially does mean “colorless” or “transparent” and is essentially a “color” choice which shows the natural metallic color of the zinc coating. What is Clear Zinc Plating? Zinc plating in general can be broken into two primary steps. The first step is to add the zinc plating, through

  • Automotive Plating

    This led to the increased use of an automotive metal finishing technique called electroplating. In simple terms, metal plating entails the deposition of metal ions onto the surface of a metal part, which is known as the substrate. These metal ions are one component used to produce an electrolyte solution, commonly referred to as a plating bath.
