Origin of temperature-induced low friction of sputtered Si-containing amorphous carbon coatings

Origin of temperature-induced low friction of sputtered Si-containing amorphous carbon coatings

This work reports on a tribological study of magnetron-sputtered silicon-containing amorphous carbon thin films vs. their alumina counterparts. Temperature cycling during ball-on-disk tests in humid air revealed a decrease in the coefficient of friction from 0.3 to
