9Cr18钢上离子束辅助沉积TiC_xN_y膜的研究
Study of TiCxNy films formed by ion beam assisted depositionon 9Cr18 steel
【摘要】 用离子束辅助沉积技术在9Cr18钢基体上形成了TiCxNy膜。TEM观察膜呈多晶结构,具有(111)、(200)和(220)择优取向。AES和XPS分析进一步证实,TiCxNy膜呈含氧配置。膜的硬度与N含量有关,N的含量过高时硬度下降。在本实验条件下以离子注量为3x1017/cm2时硬度最高,干摩擦表明膜的抗氧化性能优良,它的存在能有效抑制基体在摩擦过程中氧化皮的形成,显著改善基体的磨损特性,并能使基体由粘着磨损向磨粒磨损转化.
【Abstract】 The TiCxNy films were formed on 9Cr18 steel matrix using the ion beam assisteddeposition. The TEM analysis revealed the films with a polycrystalline structure with(111), (200) and (220) preferred orientation. The fact that TiCxNy films contain oxygencoordination was further confirmed by AES and XPS. Microhardness of the films wasfound dependent on its N content, and it was decreased for an excessively high Ncontent. An assisted dose of 3 X 1017/cm2 is optimum in this experiment. A dry frictiontest indicated that oxidation resistance of the films is excellent, and oxidation of thesteel matrix in the friction process can be obviously inhibited. Both the abrasive andadhesive wears of matrix are improved, and a trend of transformation from adhesiveinto abrasive wear appears for the steel matrix.
