Ball Burnishing as Finish Method of Compressor Shaft Wear Sleeve


Nowadays more and more advanced technologies in surface finish are developed. The ball burnishing technology of wear sleeve gives smoothened surface characteristics, which im-proves initial abrasive wear resistance, bearing rate, and residual compressive stresses in the surface layer of the wear sleeve. These parameters may significantly increase the life cycle of PTFE seal-ing knot. This paper recognizes the technology advances in wear sleeve manufacturing and gives directions for further research and discussion
