Influence of albumin on the tribological behavior of Ag-Ti (C, N) thin films for orthopedic implants

The results revealed that the coatings with Ag content ranging from 4 to 8 at.%, were the most promising, as the tribological properties were superior to the results reported by other authors, which also developed Ag-TiCN coatings containing similar Ag contents and using similar test conditions. The presence of albumin leads to a lower wear in all the test conditions, and this enhancement was higher in the hydrophobic surfaces.
