Effect of laser textured surface with different patterns on tribological characteristics of bearing material AISI 52100

Abstract

Chrome steels are used in bearings since they possess high strength and wear resistance. However, when those parts are in service, failure happens due to sliding friction before the lifetime. To improve the durability of the American Iron and Steel Institute (AISI) 52100 chromium steel, in this work, the effect of laser surface texturing (LST) was analyzed. With the different patterns of circle and ellipse comparing with the untextured samples, the wear behavior was investigated using the pin-on-disc tribometer. The lubricant used for wear analysis is semisolid lithium grease National Lubricating Grease Institute lubricant (SKF NLGI-3). Sliding wear analysis was conducted at different loads of 10 N, 30 N and 50 N for the sliding speed of 750 r/min and 1400 r/min. The wear morphology was analyzed using a scanning electron microscope(SEM). The roughness of the samples was found using a white light interferometer. The effect of different patterns like circle and ellipse, alter the friction and wear properties of chromium alloy was observed compared with the untextured samples. LST shows considerable reduction in friction and wear for ellipsoidal pattern compared with the circular pattern because of wear debris and lubricant getting trapped.
