METHOD OF HARDENING SURFACE OF METALLIC PART, PISTON, CYLINDER HEAD, AND CYLINDER BLOCK EACH PRODUCED USING THE SURFACE-HARDENING METHOD, AND PROCESS FOR PRODUCING THE SAME |
摘要 |
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. |
