Technical Examples
  1. The present invention teaches a method for surface treating an engine valve made from titanium or titanium alloy in order to form a hardened coating having a high level of adhesion to the surface of the engine valve, and also having improved abrasion and impact resistances. The method includes a hardening treatment process for forming a hardened layer on the surface of the engine valve by providing oxygen dissolved into the surface of the engine valve as a solid solution; and a coating treatment process applied after the hardening treatment process. The coating treatment process forms a coating on the surface of the engine valve by physical vapor deposition.
