A State Of Art On Hardfacing Processes and base Materials Used in Steel

摘要

The life and performance of machine is reduced mainly due to wear. Wear depends upon various factors namely corrosion, friction, hardness, surface layer, abrasion and erosion. Most of machines are not worn due to single factors, but a combination of various factors. According to numerousresearchers reliable and cheapest way of reducing the wear phenomena is hardfacing.In the previousyears hardfacing became a topic of intense development correlated to wear resistant applications. Welding deposits can improve surface property and extending their service life.Different studies have been made by the researchers focusing on various aspects of hard facing of different alloy. In present paper an attempt has been made to review the various heat facing method and base alloy used for steel.
