TiSiN/CrVxN硬质多层膜的抗氧化机理以及摩擦学行为研究

摘要: 全球因摩擦和磨损而造成的能源消耗和资源浪费日益严重,研发环境友好型固体润滑材料以解决严苛工况下减摩和耐磨问题是当今摩擦学领域的热点。含钒(V)的过渡族金属氮化物涂层材料因在高温范围内能原位生成具有层状结构的Magneli相而体现出优异的自润滑性能,得到了国内外相关领域学者的广泛关注。但其氧化机理的不明确限制了这类涂层材料性能进一步提升。本文通过利用直流磁控溅射技术制备了一系列的TiSiN/CrVxN自润滑涂层材料,研究了V对其抗氧化和摩擦磨损性能的影响规律。结果表明,涂层在高温氧化过程中会出现明显的两层氧化层,其中顶层为疏松的Ti(V)O2;底层为具有保护作用的氧化层,由铬的氧化物和硅的氧化物组成。V在高温环境下的迁移释放及其氧化导致涂层抗氧化能力随着V含量的升高而逐渐减弱。在室温条件下,V元素的添加能够显著的提升涂层的耐磨损性能,但是对这类涂层材料的摩擦系数的影响不大。

 

Insights into the oxidation resistance mechanism and tribological behaviors of multilayered TiSiN/CrVxN hard coatings

Abstract: In the last decades, vanadium alloyed coatings have been introduced as potential candidates for self-lubrication due to their perfect tribological properties. In this work, the influence of V incorporation on the wear performance and oxidation resistance of TiSiN/CrN film coatings deposited by direct current (DC) reactive magnetron sputtering is investigated. The results show that vanadium incorporation significantly decreases the oxidation resistance of the coatings. In general, two layers are formed during the oxidation process: i) Ti(V)O2 on top, followed by a protective layer, which is subdivided into two layers, Cr2O3 and Si–O. ii) The diffusion of V controls the oxidation of V-containing coatings. The addition of vanadium improves the wear resistance of coatings, and the wear rate decreases with increasing V content in the coatings; however, the friction coefficient is independent of the chemical composition of the coatings. The wear of the V-containing coatings is driven by polishing wear.
