A study of Surface wear of Hardened Cast Iron

Abstract

Grey cast iron is one of the most prominent iron products that has its application worldwide. The foundations of the machine tool and the body of an internal combustion engine are the critical cast iron applications. But one of the problem in cast iron is the wearing of surface, which generally occurs in grey cast iron. Various researchers have investigated this phenomenon and have put forward their observation. This paper pen down their investigations on wear effect and discusses some investigations on laser surface hardening to improve the cast iron's characteristic.
