A tribological study of shot peening process on stainless steel

Abstract

The goal of this study is to figure out how to use the microstructure, friction, and wear parameters of a shot-peened stainless steel 316L surface to study tribology. Tribology is the study of how moving parts rub against each other, wear out, and are oiled. Tribology looks at all of these things from a mechanical point of view. Improves the surface and frictional properties of materials, making them less likely to break and giving them a longer life. Because of this, it can make materials smoother and less likely to stick together. This is possible because it can improve the properties of many different materials. Shot peening is a type of cold working technique that can change the mechanical properties of materials like metals and composites. Because shot peening is a part of the peening process, this improvement is possible. Also, as a direct result of the result, a layer of compressive residual stress will form in the material. Before the process can be finished, the surface of the SS316L needs to be honed with abrasive sheets and a double-disc polishing machine. Next, a Vickers hardness test is done on the material, and then a pin-on-disc tribometer is used to study how the material wears. At the end of the process, a trinocular microscope is used to look at the structure of the substance being studied on a small scale.
