  • Mo doped AlCrSiN/Mo self-lubricating films and preparation method thereof
    Patent number: 12077842
    Abstract: Mo doped AlCrSiN/Mo self-lubricating films and a preparation method thereof are provided. The AlCrSiN/Mo self-lubricating films are prepared by doping Mo element into the AlCrSiN films, and the Mo content in the resulted films is in the range of 0.3-6.3 at. %. The films are prepared on the substrates by high power impulse magnetron sputtering (HiPIMS) and pulsed DC magnetron sputtering hybrid coating technology. The prepared AlCrSiN/Mo self-lubricating films possess high hardness, good toughness, excellent antifriction characteristics and good chemical stability.
