摘要
采用电弧离子反应沉积技术在SCM415渗碳淬火钢基片上沉积了Cr-Si-C-N薄膜,三甲基硅烷(TMS)反应气体作为Si和C掺杂源,通过改变TMS流量实现了薄膜中Si和C含量的调节.利用XPS,XRD,HRTEM和显微硬度计研究了Cr-Si-C-N薄膜的化学状态、显微组织和显微硬度.Cr-Si-C-N薄膜中的Si和C含量随TMS流量的增加而单调增加.在TMS流量小于90 mL/min时,薄膜中Si和C含量较少,薄膜由Cr(C,N)纳米晶与Si3N4非晶(nc-Cr(C,N)/a Si3N4)组成,薄膜硬度随流量的增加而单调增大,最大至4500 HK.硬度的增加源于固溶强化及薄膜中纳米晶/非晶复合结构的形成;当TMS流量大于90 mL/min时,薄膜中Si和C含量较多,多余的C以游离态形式存在,且随TMS流量的增加而增多,薄膜硬度下降.
