METAL COMPONENTS WITH SILICON-CONTAINING PROTECTIVE COATINGS SUBSTANTIALLY FREE OF CHROMIUM AND METHODS OF FORMING SUCH PROTECTIVE COATINGS

摘要

Metal components with a protective coating containing silicon and a process for forming such protective coatings. The protective coating is formed by applying a silicon-containing fluid composition to the metal component as a silicon-containing layer and then heating the silicon-containing layer to a temperature exceeding 400° F.
