Title:
SINTERED CAMSHAFT
Document Type and Number:
Japanese Patent JPS61270518
Kind Code:
A
Abstract:
PURPOSE:To improve wear resistance in the captioned camshaft by melting, rapidly cooling, and solidifying the sliding surface part of a cam made from sintered alloy and thereby reducing void in the sliding surface part while minimizing and homogenizing the particle size of composite material making the sliding surface part. CONSTITUTION:After sintered cams 2 is formed by sintering, the sliding surface part 8 thereof is heated to a high temperature so as to be melted with the aid of a TIG arc or the like as a high density energy irradiation means. Thereafter, the melted sliding surface part 8 is hardened by rapidly cooling and solidifying through the self-cooling of base material.
