What is ball burnishing?
Ball burnishing is a simple, rapid, cost-effective and superfinishing process which is generally carried out to better the surface integrity of mechanical parts. The aim of this paper is to investigate the optimum surface roughness and microhardness of AZ91D magnesium alloy by utilizing ball burnishing process.
What is the purpose of burnishing?
Both internal and external surfaces can be burnished using an appropriate tool. Burnishing improves the surface finish, surface hardness, wear-resistance, fatigue and corrosion resistance. Sinotech offers an exceptionally wide range of secondary processes that are applied to metals formed in hot or cold processes.
