金属部材の表面硬化方法
Document Type and Number:
Japanese Patent JP5101838
Kind Code:
B2
Abstract:
With regard to a surface hardening method that a surface of an engine member is coated with an alloy layer having high abrasive resistance so as to improve life of the member and a production method of a piston or the like that abrasive resistance of the member is improved by the hardening method, a surface of a metal base material is coated uniformly with mixture including metal powder, a binder and solvent so as to form a coat, and the coat is dried and applied thereon with laser or electron beam so as to be sintered and dispersed for forming an alloy layer on a surface of the metal base material and for bonding the alloy layer to the metal base material.
