Hardfacing With Saw Method on Mild Steel – A Critical Review

Abstract

Life of any machine elements depends on its wear out rate. Most of working components are fracture and reduce its dimension, due to wear. The main reason of wear out any mechanical component is abrasion, impact, metallic (metal to metal) heat, corrosion etc. Large number of researchers performed experiments on different machines and equipment with different life extension technology, but few of them focused on hard-facing coating technology. Economically use of hard-facing technique depends on type of material used and its chemical composition. Carbon and chromium are the major elements which are used in hard-facing method. It was found that by varying the percentage of carbon and chromium, corrosion and wear resistance can be enhanced. In this paper an attempt has been made to review different hard-facing techniques and materials used for the same and the current research being done.
