In order to search for new compositions and structures of wear-resistant and protective coatings, the study of multi-element gradient-layered coatings (Ti, Al, Si, Cr, Mo, S) O, N has been carried out. Using the methods of scanning, transmission electron microscopy, X-ray photoelectron spectroscopy, indentation, scratching and tribotesting, the composition, structure, and mechano-tribological properties of the coatings were studied. It was found that the pattern of the deformation relief of the wear track corresponds to various scales and mechanisms of destruction, from uniform destruction of the nanocrystalline layer to large fracture centers containing areas of substrate deformation, destruction and coating spalling, thick amorphous surface tribofilms of wear products. In general, the results obtained indicate an abrasive-oxidative wear mechanism. An increase in the level and heterogeneity of elastic strains and stresses, expressed in the development of a rotational deformation mode along the boundaries of nanocrystals, in the surface layer of the friction zone is established. In connection with the study of the phase composition of the friction zone, it was suggested that oxygen saturation significantly affects the decomposition of the phase of doped titanium nitride into amorphous wear products.

梯度层(Ti,Al,Si,Cr,Mo,S)O,N的结构和摩擦学性能,梯度层(Ti,Al,Si,Cr,Mo,S)O,N的结构和摩擦学性能,梯度层(Ti,Al,Si,Cr,Mo,S)O,N的结构和摩擦学性能

为了寻找耐磨和保护性涂层的新组成和结构,已经进行了多元素梯度层涂层(Ti,Al,Si,Cr,Mo,S)O,N的研究。使用扫描,透射电子显微镜,X射线光电子能谱,压痕,刮擦和摩擦测试的方法,研究了涂层的组成,结构和机械摩擦学性能。发现磨损轨迹的变形消除图案对应于各种尺度和破坏机理,从纳米晶层的均匀破坏到包含基底变形,破坏和涂层剥落,厚的无定形表面摩擦膜的大断裂中心。穿着产品。一般来说,获得的结果表明了磨料-氧化磨损机理。在摩擦区的表面层中,建立了沿着纳米晶体边界旋转变形模式发展的弹性应变和应力的水平和非均质性的增加。结合对摩擦区相组成的研究,表明氧饱和度显着影响掺杂的氮化钛相向无定形磨损产物的分解。
