    摘要:

    考察鎢含量和摩擦條件對摻鎢DLC涂層摩擦性能的影響。結(jié)果發(fā)現(xiàn)：隨著鎢含量的增加，DLC涂層摩擦系數(shù)明顯增加；鎢含量為3.1%(原子分?jǐn)?shù))的摻鎢DLC涂層的耐磨性最好。在干摩擦條件下，低鎢含量的DLC涂層摩擦系數(shù)隨著載荷的增加而有所增加，高鎢含量的DLC涂層在高載荷時具有較低的摩擦系數(shù)；高鎢含量的DLC涂層的摩擦系數(shù)隨著轉(zhuǎn)速的增加而增加，但轉(zhuǎn)速對純DLC涂層的摩擦系數(shù)影響很小。摻鎢DLC涂層的磨損主要是由Si3N4球壓入試樣表面時涂層在變形過程中的微觀斷裂和剝落引起的

    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
