An Analysis on the Influence of Surface Characteristics and Operating Parameters on the Wear of Hardened AISI 52100

Abstract:

The objective of the research was to analyze the influence of initial roughness on the wear rate of component samples made of bearing steels. AISI 52100 samples were prepared with three different roughness values by varying the depth of cut and feed rate in milling process. Dry reciprocating wear tests were performed under the same laboratory conditions and at different loads and sliding speeds. A fractional factorial approach with one-third of 33 experimental design without replication was followed here. The overall wear rate was found out by mass loss method. The results were analyzed using contour plots between the factors influencing the wear rate as well as mean coefficient of friction. The results indicated that the wear rate and coefficient of friction was influenced by load, roughness and their interaction.
