A layer of TiCN or TiAlN can also be applied over a TiN coated part. There are limits to how many times a part can be recoated, however. After numerous recoats, the coating may develop flaws in the areas that are not reground. BryCoat applies pure coatings. No additive is used to color the coatings.
TiN looks similar to gold or polished brass.
TiCN is a gray color. TiAlN is brownish. CrN looks like chrome. Let us know how we can help you. We will be happy to discuss a coating or surface engineering application, or to simply send literature to you.
