Summary:

This research is limited to study the strength and wear resistance of 20MnCr5 (SAE 5120) alloy steel under monolithic, case hardened and case hardened with shot peening processing condition. Improve the hardness of the material by enhancing the core and surface strength of case hardened with the shot peened sample. The main objective of this proposed work is to conduct the tribometer test by varying the load of 10, 20, 30 and 40N and sliding speed of 193, 386 rpm respectively on wear rate and coefficient of friction be calculated and recorded for this study. Less wear rate and nominal coefficient of friction were observed for case hardened with the shot peened sample. Load increases wear rate increases and the coefficient of friction decreases when sliding distance increases wear rate decreases and the coefficient of friction increases for all the tested samples due to oxide layer formation. After reaching certain load and sliding speed the curve goes linear because of more contact between pin and disc, so that mechanical amalgamation layer will be formed. On the other hand worn out surface was observed by using a scanning electron microscope and reveals the absence of microcrack, continuous groove formation of the worn out sample
