Abstract

According to one embodiment, a cladding 5 portion is integrally formed on a sliding-contact surface of a valve rod or a valve body, which serves as a movable member, wherein the cladding portion is formed by inducing a pulsed discharge between an electrode which 10 is formed of a molded body consisting mainly of a metal and a treatment target portion of the valve rod or the valve body, so as to weld and deposit a material of the electrode on a surface of the treatment target portion. A surface layer is integrally formed on a sliding15 contact surface of a bushing or a sleeve, which serves as a stationary member, wherein the surface layer is formed by forming a first coating film by surfacehardening heat treatment using a metallic cementation.
