The effect of sandblasting on AISI 316L stainless steels

In this paper, the study of the sandblasting effect of AISI 316L stainless steel for medical implant is conducted to find out the mechanical properties of the implant after the treatment. Sandblasting is a method to change thesurface quality by impacting the surface with the silica material. The impact time variables used in thisexperiment are 2, 6, 10, 16 and 22 minutes. The results show that the longer sandblasting time, the surfaceroughness becomes higher. The sandblasting creates change on the steel surface which correspond to increasingroughness from 0.67 μm to 1.46 μm, The variable of rotational speed during sandblasting at 45 rpm rotationalspeed produce poorer surface roughness (1.18 μm).
