ABSTRACT:
A method for fusibly bonding a coating material to a metal article includes depositing such coating material in solid form on a surface of the article, substantially simultaneously thermally liquifying the coating material and the surface of the article by focusing a relatively high power continuous wave laser beam thereon, and removing the laser beam therefrom to allow cooling and hardening thereof so as to provide a solidified surface layer with a strong and relatively thin interstitial bond between the layer and the article. An exemplary engine valve with a relatively fine structure of the coating material for increased hardness is disclosed.
