Abstract
Gas carburization has been used in order to improve mechanical properties of steel surface hardening in engineering industries. In this investigation optimization of gas carburization process parameters for wear resistance on AISI 1020 low carbon steel has been done by using Taguchi approach. 4 Design of experiments is done on the basis of an orthogonal array L9 (3 ). Nine experiments are performed on the basis of L9 Taguchi approach by using various process parameters like carburizing temperature, soaking time, tempering temperature and temperature time. Signal to noise (S/N) ratios, MEAN ratio Taguchi analysis is performed in order to obtain response variable like wear rate. It is observed during investigation that heat treatment is followed by quenching and tempering tremendously improves wear resistance of AISI 1020. In order to predict optimal parameter, confirmation test is conducted for implementation of L9 Taguchi approach. This study concludes that wear resistance has been improved after the gas carburization process.
