Review of Effect of Burnishing Process on Surface Integrity of Friction Stir Welded Components

Abstract

Burnishing is a technique of surface improvement that enhances the component's surface finish along with the component's surface properties. It is a cost-effective technique often utilized in the aerospace, biomedical or automotive industries to increase the component's reliability and performance. The response parameters in the burnishing process depend on the burnishing process parameters, the instrument and the burnishing material. Burnishing is a very simple and efficient surface finish improvement procedure and can be done with existing machines, such as shrink.

It also saves money on manufacturing costs due to its high efficiency than other traditional processes, such as super finishing, honing and grinding. In comparison, the burnished surface is extremely resistant to wear and has a longer fatigue life. The burnishing method is an appealing finishing technique that strengthens the work-surface piece's integrity to improve fatigue behaviour under complex loadings.
