摘    要:采用高温座滴法测定了一系列金属及合金在TiO上的接触角。研究结果表明:金属Cu, Fe, Co, Ni及Fe-Cr合金与TiO的润湿性均较差,在熔点温度时其接触角为48°~120°。Cu与TiO属非反应型润湿; Fe, Co, Ni及Fe-Cr合金与TiO属反应型润湿。添加某些表面活性剂能提高其润湿性,向Cu中添加2%以上的Mo2C可明显提高Cu在TiO上的润湿性,由非反应型润湿转变为反应型润湿;向Fe-Cr合金中添加1.5%以上的Mn或Si,可显著提高Fe-Cr合金在TiO上的润湿性,添加Mn不改变润湿类型,而添加Si使反应型润湿转变为非反应型润湿。附件: Z2005-03-18

Abstract: The wetting angles of various metals and their alloys were determined by high temperature sessile drop method. The results indicate that the wettability of Cu, Fe, Co, Ni and Fe-Cr alloy on TiO surface is not good, and the contact angles are 48°~120°at melting point temperature; Cu on TiO surface is non-reaction wetting, and the others are reaction wetting. But the wettability can be improved by adding some surfactant. The wettability of Cu on TiO surface can be improved effectively by adding more than 2%Mo2C, and at the same time the non-reaction wetting is changed into reaction wetting. The wettability of Fe-Cr alloy on TiO surface can be improved markedly by adding more than 1.5%Mn or 1.5%Si; the wetting type is not changed by adding Mn, but the reaction wetting is changed into non-reaction wetting by adding Si.
