Abstract

PURPOSE: To improve wear resistance by forming a pad layer for dispersively holding hard particles on a substrate made of Fe-base alloy, Ni-base alloy or Co-base alloy or their alloy by powder pad welding on the surface to be used.
CONSTITUTION: A pad layer for dispersively holding hard particles is formed on a substrate made of Fe-base alloy, Ni-base alloy, or Co-base alloy or their alloy by powder pad welding on the surface to be used of a plunger for resin- molding an IC. Since a material can be selected irrespective of the productivity of a welding rod in the pad welding, manufacture of a plunger having higher performance can be performed. A preform can use carbon steel, alloy steel for mechanical structure, hot or cold treated tool steel, stainless steel, austenite alloy, and suitably use austenite hot treated die steel due to strength of thread bond, toughness and easiness of pad welding. The particles use WC, TiC, TiN, TiB2, VC, SiO2. Thus, wear resistance can be increased to improve the life of a tool.
