Surface generation of superior hydrophilicity for surgical steels by specific grinding parameters

In the present study, electrolytic in-process dressing grinding was performed on surgical steels (type 420J2 stainless steel) and the processing characteristics and resulting surface properties were evaluated. In particular, we used different grinding abrasives to investigate the effect of grinding parameters on the surface hydrophilicity of the processed workpieces. The results confirmed that surfaces processed with alumina abrasives in a grinding fluid at temperatures over 50 °C have the highest hydrophilicities. Furthermore, they also exhibit excellent corrosion resistance.
