摘　　要：钛及其合金具有优良的性能被广泛应用于武器装备领域,但在磨料条件下易黏着、不耐磨的特性限制了其使用。为了提高钛在磨料作用下的减摩抗磨性能,以TA2钛为研究对象,使用激光加工技术在TA2样品表面上制备点阵微织构,然后采用磁控溅射技术在点阵微织构表面制备类金刚石碳(Diamond-like Carbon,DLC)薄膜,形成DLC复合微织构;采用MS-T3000摩擦磨损试验机研究了DLC复合微织构表面在磨料作用下的摩擦磨损性能,并通过扫描电子显微镜、能谱分析、拉曼测试、有限元分析等手段研究钛表面DLC复合微织构的摩擦磨损机理。结果显示DLC复合微织构表面可有效提高钛在磨料条件下的减摩抗磨性能,且同等条件下,点阵密度对DLC复合微织构样品表面摩擦因数的影响最大,单位面积点阵边缘密度值与样品表面磨损率有关,且二者基本呈正线性关系。揭示了DLC复合微织构在磨粒磨损条件下的摩擦磨损性能,并从织构边缘的破坏提出磨损机理,研究结果可为钛在磨料磨损条件下的应用提供理论和设计依据。For more than one hundred years,researchers have been investigating the tribological behavior of certain materials.Their studies concentrated mostly on adding lubricants or modifying the material surface.Unfortunately,these methods do not always guarantee effectiveness in special conditions,such as under abrasive wear.The application of surface texturing on rubbing pairs has been demonstrated to improve the abrasive wear property of certain materials.Titanium and its related alloys are one such type of materials that exhibit excellent properties and are widely used in important fields such as weapon equipment,civilian products,and the chemical industry.However,applications of titanium and its related alloys are limited by its easy adhesion and poor wear resistance under abrasive wear conditions.Therefore,it is of great significance to study the friction reduction and wear resistance performance of surface-textured titanium under abrasive conditions.Many scholars have conducted extensive research on the friction and wear properties of textured surfaces.However,the quantitative relationship between the texture edge and wear resistance property has not been further investigated.The purpose of this study is to investigate the effect of the texture edge on abrasive wear performance.The substrate selected is a commercial pure titanium grade 2(TA2),which has poor tribological behavior under abrasive wear.To prepare the diamond-like carbon(DLC) composite textured surface,an indirect laser processing method(i.e.,laser processing before DLC film deposition) is chosen to prevent the DLC film from being damaged by laser exposure.Dimple textures are prepared on the surface of TA2 using laser processing technology.The dimple texture parameters are designed by using orthogonal analysis to equalize sampling so that the results do not depend on subjective factors.Afterward,DLC film is deposited on the dimple textured surface using magnetron sputtering.The DLC composite textured surfaces are obtained through the above processing m
