The effect of shot peening on tribological behavior of alloyed steels

Abstract

Quality of the contact surface, from tribological aspect, represents complex of microgeometry characteristics, among which parameters of the structure and microgeometry shape have special significance, and range of indicators regarding physical-mechanical state of the material in thin surface layer. Results of laboratory investigations presented and analysed in the paper are related to effects of using final machining by shot peening as a surface plastic forming, and they are further validated by friction and wear testing. Based on the overall tribological effects, it can be concluded that final machining of contact surfaces by shot peening can contribute to improvement of tribological level of tribo-mechanical system elements.
