Title: Machining method for metal fitting surfaces
Inventor: OKAMOTO HIDEO
IPC: B23P17/00
Filed: 1992-10-29
Abstract: PURPOSE:To provide a machining method to obtain metal fitting surfaces with no rust or no mixture of foreign matter, which needs no lubricant, and can carry out an additionay processing easily. CONSTITUTION:To metal fitting surfaces 1a and 2a,a ceramic powder is flame- sprayed, then the flame-sprayed surface is polished, and furthermore a lapping is applied. Since the fitting surfaces 1a and 2a are covered with a ceramic layer to increase the hardness, and the smoothness is made high by applying the polishing and the lamming, the abrasion is hardly generated. Since no quenching is applied, a stainless steel, a brass, and a soft metal generating no rust can be used, when only a flame spray of a ceramic powder is available. Consequently, the rust is never generated, and an after treatment can be carried out easily. Furthermore, since the ceramic layer is never dissolved, a lubricating oil is unnecessary to feed, and a problem of mixing a lubricant is solved.
