Title:
A manufacturing method of the pin for chains which has abrasion resistance
Document Type and Number:
Japanese Patent JP6118144
Kind Code:
B2
Abstract:
Problem. To provide a chain pin which makes it possible to improve wear resistance even in an environment in which degraded oil is used. Solution. A large number of pins are mixed/agitated together with a particle mixture including a penetrant comprising chromium (Cr) powder and tungsten carbide (WC) powder, and an iron chloride (FeCl3) catalyst, and WC particles penetrate the surface of the pins together with chromium carbide (CrC). As a result, a chromium carbide layer in which WC particles are diffused in a CrC layer (CrC—WC layer) is formed on the outermost surface part of the steel forming the parent material of the pins.
