Black Oxide


Do you want to protect your products but are you scared that they won’t fit into your machine after treatment? That’s possible! By putting black oxide on your products Special Platings makes sure that your products are corrosion proof without a significant increase in surface.

Black oxidation is meant for products with a very tight fit (+/- 0,01mm). This is because black oxidation causes a chemical conversion in the top layer of the product. The corrosion resistance with black oxidation is less than with regular galvanization, this is because the coverage is very thin, we have to do this to guarantee the fit of your products.

After the black oxidation process but before finishing we will treat your products with oil. This oil will contribute to the corrosion proof properties of the black oxide coating.
