Abstract

This work presents the effect of various wear environments like 20% soil & 80% sand and 40% soil & 60% sand on as received and carburized mild steel sample at different load like 75N, 200N & 375N and at different tempering temperature like 200ºC, 250ºC & 300ºC. The mild steel sample was carburized at 950ºC. The heat treatment after carburization has been acknowledge that at some instant it improving the various properties of mild steel. The mechanical properties and wear behaviour of mild steel samples carburized at temperature of 950ºC and tempered at different tempering temperature of 200ºC, 250ºC & 300ºC have been studied and it is observed that the sample with heat treatment improves the hardness, tensile strength and wear resistance of mild steel. For this experiment firstly the mild steel samples are carburized at temperature 950ºC than soaking for two hour and then it is tempered at different temperature range of 200ºC, 250ºC & 300ºC for 1h, 1.5h, 2h. After this the carburized and tempered mild steel samples are subjected for different kind of test such as abrasive wear test at different load like 75N, 200N & 375N, and tensile test. the result of these experiment shows that the carburized and tempered process greatly improve the mechanical and wear properties like hardness, tensile strength and wear resistance and these properties increases with increase in tempering temperature. The aim of these experiments is to examine the effects on mechanical and wear properties for mild steel samples which were carburized and tempered at different temperature and various wear environments.
