Cu-Mo-C在TiO上的润湿性研究

Study on the Wettability of Cu-Mo-C on TiO

研究了Cu在一氧化钛上的润湿及Mo、C的加入对其润湿性的影响。结果表明Cu在一氧化钛上的润湿属非反应型润湿,但存在相间溶解。纯Cu在一氧化钛上的润湿性较差,在真空条件下1083～1450℃接触角为120～68°。Cu中加入Mo、C,在润湿过程中Mo、C在TiO/Cu界面富集,并形成Mo、C与Ti(C、O)的固溶体混合物,可显著改善润湿。加入Mo、C2％以上。

The wettability of Cu on TiO and the influences of Mo.C were studied in this thesis.The results indicated that the wetting of Cu on TiO belonged to no-reaction wetting,and the wettability was not well,the wetting angles were 120-68° at 1083~1450℃ in vacuum.Mo and C would enrich on the wetting interface when they were added into Cu,and forming compounds of Mo,C and Ti(C.O),improving the wettability notability.The wetting angle could he reduced to less than 20° when the content of Mo.C was abcve 2%.
