| 摘 要： | 考察钨含量和摩擦条件对掺钨DLC涂层摩擦性能的影响。结果发现:随着钨含量的增加,DLC涂层摩擦系数明显增加;钨含量为3.1%(原子分数)的掺钨DLC涂层的耐磨性最好。在干摩擦条件下,低钨含量的DLC涂层摩擦系数随着载荷的增加而有所增加,高钨含量的DLC涂层在高载荷时具有较低的摩擦系数;高钨含量的DLC涂层的摩擦系数随着转速的增加而增加,但转速对纯DLC涂层的摩擦系数影响很小。掺钨DLC涂层的磨损主要是由Si3N4球压入试样表面时涂层在变形过程中的微观断裂和剥落引起的。

| Abstract: | The influences of W content and friction condition on the tribological properties of W-doped diamond-like carbon (DLC) coatings were studied. Results show that the friction coefficients of W-doped DLC coatings is augmented with the W content increasing; the W-doped DLC coatings with a W content of 3.1% exhibit the best film/substrate adhesion and wear resistance. Under the dry friction condition, the friction coefficients of W-doped DLC coatings with a low W content are increased with the rise of load while low friction coefficients of W-doped DLC coatings with a high W content are found at a high load; the friction coefficients are increased with the rotation rate increasing for the DLC coatings with a high W content, but the influence of the rotation rate on the friction coefficients of un-doped DLC coatings is unobvious. The wear of W-doped DLC coatings are produced by the micro-fracture and peeling in the coatings during the indentation of hard Si3N4 ball into the sample surface |
