Wear resistance of nanolaminar coatings with diamond-like carbon and titanium-carbon nanocomposit layers
Abrasive wear resistance of nanocomposite films with carbon diamond-like component has been studied. The film consists from TiC and hard diamond-like carbon layers thickness not more than 100nm of each layer. Carbon layers deposited by impulse arc sputtering of graphite target, first process, and by decomposition of a hydrcarboncontaining gas in glow-discharge plasma, second process. The concentration of carbon in films depend from frequency of pulses and pressure of acetylene in chamber. he wear resistance of samples was carried out in jet of abrasive particles diameter about 100mcm falling perpendicularry on sample surface with velocity 10 m/sec. It was established that wear resistance of such films depend on carbon concentration. Such films are perspective for increase of wear resistance of cutting tools.
