SURFACE TREATMENT FOR IMPROVED HARDNESS AND CORROSION RESISTANCE |
摘要 |
An article is protected with a wear-resistant coating. The wear-coated article is thereafter treated to produce a chemical conversion coating on any portions of the surface of the article accessible through micropores in the wear-resistant coating. For steel articles, the wear-resistant coating is preferably a titanium nitride-based intermetallic compound such as TiN, Ti2N, (TiAl)N, Ti(CN), (TiAl)(CN), ZrN, and CrN, and the chemical conversion coating is preferably a phosphate-based compound. |
