Abstract

Ag and Ag/Ti films were deposited on ZrO2 substrates by ion-beam-assisted deposition. Adhesion of these films was measured before and after heat treatment at 250°C in air. The results show that a graded interface between Ag and Ti was necessary for the Ag films to survive the heat treatment. Reciprocating pin-on-disc tests were performed at 150°C after heat treatment to investigate the relationship between adhesion and tribological properties. The failure of Ag and Ag/Ti (without graded interface) films was also observed during wear tests. However, this Ag film failure did not result in negative effects. All three Ag-coated substrates show better tribological behavior.
