Influence Of Al2O3 Particle Content On The Sliding Wear Behaviour Of Za-27 Alloy Composite

Abstract

Shot peening processing is used to increase static and dynamic strength of the working part. Not just a change of surface layers characteristics but also a change of tribological characteristics can be obtained by using this method. Results of laboratory investigations presented and analysed in this paper are related to effects of final machining by shot peening as a surface plastic forming, and they are further tribologically validated by wear tests using 36NiCrMo16 alloyed steel. Tribological investigations showed that total effects of final machining by shot peening have positive influence on tribological behaviour of machined parts and that they can contribute to improvement of tribological level of tribomechanical elements.
