Abstract

The tribological behavior of medical SUS316L stainless steel on soft-tissue-like poly(vinyl alcohol) (PVA) hydrogel with and without dimethyl sulfoxide (DMSO) was investigated in physiological condition. In lower sliding velocity region, the maximum friction coefficient (μmax) is observed at certain velocity due to the adsorption of polymer chains on SUS316L. The presence of plasma proteins into liquid largely reduced μmax of SUS316L. Among plasma proteins tested, we found that mostly Human Serum Albumin was adsorbed on SUS316L, inhibiting the adsorption of PVA chains onto SUS316L.
