• BLACK OXIDE COATINGMIL-C-13924 - Black Oxide Coating for Ferrous MetalsBlack Oxide is a surface treatment which forms an oxide coating on the surface ofsteels and stainless steels which is black. Its main application is to change thecolor of the steel without risk of chipping or peeling where a coating of oil ispermissible. Black oxide has no corrosion protective properties on its own, but itdoes make a superior surface for the application of oil to keep the surface fromrusting. Common uses for black oxide are tooling, small screws for consumergoods, engine parts and firearms. The hot black oxide treatment is a better blackoxide coating in both function and appearance; however, when the part does not fitinto the processing bath, the cold process is a good alternative.• PASSIVATIONASTM A967 - Standard Specification for Chemical Passivation Treatments forStainless Steel PartsPassivation of SS is a process which treats the surface of the metal to impedecorrosion. The process has two primary functions: first, to remove any free iron onthe surface of the material. Second, to promote the growth of nickel and chromeoxides which give stainless steel its excellent corrosion resistant properties.Passivation does not remove discoloration or heat scale from the surface of thepart. An additional acid pickle, an alkaline descale or mechanical blasting arerequired to remove such material from the surface. Passivation is used in manyindustries and a broad spectrum of stainless steel and nickel alloys can bepassivated. It should be noted that if a stainless steel is improperly heat treatedthere is a risk of etching the parts in the passivation process.www.skyemetalcoating.com
