摘要

采用脉冲直流磁控溅射法制备了碳化钨/碳化硼（W/B4C）周期性纳米多层涂层（pnc）；在15 ~ 50瓦的溅射功率范围内，研究了溅射功率对pnc结构和摩擦学性能的影响。最高的机械和摩擦学性能是在35瓦的沉积速率下实现的，这些性能归功于PNC的高均匀性、高致密性和低混合。此外，还观察到磨损轨迹表面石墨化的形成，这也是W/B4C PNC涂层磨损减小的原因。为了获得具有优异机械性能和摩擦学性能的涂层，应将W沉积功率调节到合适的范围。

Enhanced mechanical and tribological performance of W/B4C periodic nano-multilayer coating by optimizing W deposition power

Tungsten/Boron Carbide (W/B₄C) periodic nano-multilayer coatings (PNCs) were deposited by pulse DC magnetron sputtering; the effect of W sputtering power on the structure and tribological performance of PNCs was investigated with W power ranging from 15 to 50 Watts. The highest mechanical and tribological performance was achieved at a deposition rate of 35 Watts, and these properties were attributed to high uniformity, high compactness, and low intermixing of the PNC. Besides, the formation of graphitization on the surface of the wear track was observed, which was also the reason for the wear reduction of the W/B₄C PNC coating. The W deposition power should be adjusted to a suitable range to obtain a coating with superior mechanical and tribological performance.
