| 摘 要： | 对TA7钛合金以氩气保护等离子热喷涂金属钼，并进行保温扩散处理得到的涂层界面微观结构用金相显微镜、扫描电镜、电子探针、X射线衍射等分析手段做了较详细的分析。结果表明，采用亚音速等离子热喷涂金属钼可得到致密、基本无层状结构的涂层；界面附近合金元素的相互扩散可促进形成冶金结合，并对钛合金近界面组织结构产生一定的影响。

| Abstract: | In this paper,coating interface microstructure of TA7 titanium alloy,which was coated by the metal molybdenum with spraying in the argon atmosphere and then kept at high temperature diffusing,was analyzed with microscope,scan electrode microscope,electrode probe and X-ray diffraction etc.The results show that a solid,almost non-layer shape microstructure coating is available with subsonic speed plasma spray,the atom diffusing nearby interface would speed up metallurgical bonding,and affect titanium alloy microstructure nearby interface in certain degree. |

| Keywords: | titanium alloy thermal spraying interface coating interface |
