| 摘 要： | 采用反应非平衡磁控溅射技术制备出一系列LY12铝合金基CrTiAlN多层涂层,并通过X射线衍射仪、纳米压痕仪以及多功能摩擦磨损测试仪来研究CrTiAlN涂层的结构、力学以及摩擦学特性。结果表明:CrTiAlN涂层为以TiN0.9和CrN为主要组织取向的FCC结构,N2水平和衬底负偏压对涂层的力学特性和粘附强度有显著的影响。经过优化参数,在衬底偏压?55V和中N2水平条件下,CrTiAlN涂层的结合强度为10 N,显微硬度达到29.87 GPa。

| Abstract: | A series of CrTiAlN multi-layer coatings on LY12 Al alloy substrates were prepared using unbalanced reactive magnetron sputtering system.The structural,mechanical and tribological properties of coatings were studied by X-ray diffractometry,microhardness tester and multi-functional ball-on-disc tester.The results show that the CrTiAlN coatings belong to FCC structure consisting of TiN0.9 and CrN,and the N2 level and negative bias voltage have a significant effect on CrTiAlN multi-layer coatings.The adhesion ... |
