Experimental Investigation on the Tensile and Wear Characteristics of Journal Bearing Materials Used in Automobile Engine Application

The objective of the bearing materials is to reduce the friction and enhance the movement between two parts. The main aim of our project is to focus on the wear, tensile and fatigue characteristics of engine journal bearing material. The engine bearings are mainly classified into main bearings and journal bearings. The journal bearing material was made by cladding process. It is formed in two types of shape one is circular and the other is on dog bone shape. Both of the specimens were made as per ASTM standards. The material on which the test specimen was made on steel platted copper material and Aluminium 1020. The circular shape specimen was subjected to wear test on Pin on Disc method and the wear calculations were calculated in microns. The dog bone shape specimen was tested on tensile strength on Universal Testing Machine (UTM). The stress strain curve was obtained. The specimen will subject to fatigue test by using of fatigue test machines. Engine journal bearing materials subjected to do fatigue and microstructure analysis. The outcome of that project is to compare the results from the above tests and find out life of the bearings under all the above-mentioned conditions
