TiAlSiN coatings were produced with different Al and Si contents by hybrid PVD technology. The tribological properties of TiAlSiN coatings from room temperature to 800°C were evaluated. The friction and wear of TiAlSiN coatings show strong dependence on stoichiometry and test temperature. The formation of SiO2·nH2O tribo-layer contributes to the decrease of the wear rate and friction coefficient at...
In the present work, a special interface between substrate and carbon films is introduced to prolong wear life of a-C:H film in high vacuum, and the optimized film exhibits an ultra-long life of 2.6×105 cycles, corresponding to 9796.8m at the normal load of 5N. Experimental results show that gradient interlayer significantly decreases internal stress, increases adhesion strength as well as improves...
