摘要
文章以Ti及TiH_(2)粉为原料,分别采用等离子喷涂技术制备了Ti涂层,分析了涂层的显微形貌及力学性能。研究表明,等离子喷涂制备Ti涂层厚度约100~200μm,可观察到明显的层片结构及较多微小孔隙。Ti粉所制备涂层XRD图谱的主衍射峰为TiO,而用TiH_(2)粉所制备涂层XRD图谱的主衍射峰为Ti。Ti粉所制备涂层摩擦系数及磨损量仅为0.179及5.8 mg, TiH_(2)粉末所制备涂层摩擦系数及磨损量分别为0.294及9.9 mg,均优于304不锈钢基体。
Ti coating was fabricated by atmospheric plasma spraying with Ti and TiH_(2) powder used as raw materials,respectively.The microstructure and mechanical properties of Ti coatings were characterized.APS Ti coating(about 100~200μm)was lamellar structure with many micro⁃pores existing at the interface of lamellae.The main peak of XRD of Ti coating fabricated from Ti powder was TiO phase,while that of Ti coating fabricated from TiH_(2) powder was Ti one.Friction coefficient and weight loss of Ti coating prepared from Ti powder were only 0.179 and 5.8 mg,respectively.Friction coefficient and weight loss of Ti coating fabricated from TiH_(2) powder were 0.294 and 9.9mg,respectively.Tribological properties of these two kinds of Ti coatings were both superior than those of 304 stainless steel.
