Method of producing silicon diffusion coatings on metal articles
摘要
A silicon diffusion coating is formed in the surface of a metal article by exposing the metal article to a reducing atmosphere followed by treatment in an atmosphere of 1 ppm to 100% by volume silane, balance hydrogen or hydrogen inert gas mixture. Hydrogen with a controlled dew point is utilized as a surface preparation agent and diluent for the silane.
