Co-sputtered thin films of MoSx with Au have been deposited in order to inv
estigate the relationships between tribological behavior and film microstru
cture. The mechanical properties of the composite films were investigated b
y pin-on-disk wear testing in 50% relative humidity air as a function of Au
concentration. X-ray diffraction measurements indicate that the microstruc
ture is strongly affected by the inclusion of Au and that there is a strong
correlation between microstructure and tribological performance. (C) 2001
