Abstract

CVD diamond films are expected to become maintenance-free solid lubricant coatings. However, substrates on which diamond film can be deposited have been limited to materials such as silicon and tungsten carbides. If diamond films can be deposited onto steel substrates, it will increase the number of possible applications. Diamond film was deposited on a steel substrate with an interlayer and was partly polished. Tungsten and titanium were selected as materials for the interlayer between diamond film and AISI 440C steel substrate. Low and stable friction coefficients were obtained between diamond film and AISI D2 pin, with friction coefficient 0.1 in the steady-state regime.
