MoS_2-Au共溅射膜具有非常优异的摩擦学性能,在相对湿度小于13％、等于50％、大于98％以及高真空1.33×10~(-5)Pa的条件下,其耐磨寿命分别是MoS_2溅射膜的2.7、6.0、2.4和24倍;在相对湿度为50％的摩擦环境中,具有比MoS_2溅射膜低且稳定得多的摩擦系数。 利用扫描电镜研究了MoS_2-Au共溅射膜的表面形貌和剖面结构。作者指出,这种膜之所以有很长的耐磨寿命,是因为最后在磨损轨迹上有一层反转移膜。可以认为,这种反转移膜的形成与MoS_2-Au共溅射膜顶部的柱状聚集体结构有关。
MoS_2-Au co-sputtering film has very good tribological properties. Under relative humidity less than 13%, equal to 50%, more than 98% and high vacuum of 1.33 × 10 -5 Pa, Which is 2.7, 6.0, 2.4 and 24 times higher than that of MoS_2 sputtered films, and has a much lower and much more stable coefficient of friction than the MoS 2 sputtered films in a rubbing environment with a relative humidity of 50%. The surface morphology and cross-sectional structure of MoS_2-Au co-sputtered films were investigated by scanning electron microscopy. The authors note that the reason this film has a long wear life is due to the fact that there is finally a reverse transfer film on the wear path. It is believed that the formation of this reverse-transfer film is related to the columnar aggregate structure at the top of the MoS_2-Au co-sputtering film.
