| 摘 要： | 采用织网叠层法,以钨丝为纬线,铜丝为经线编织二维网,将网与铜坯叠放在一起,于真空烧结炉中熔渗的真空熔渗工艺制备纤维结构W/Cu触头材料。试验给出了该工艺的主要工艺参数。与粉末冶金制造的W/Cu触头材料的烧蚀性能作对比,从触头表面在电弧烧蚀后的熔层形貌分析表明,纤维结构W/Cu触头材料呈现较好的抗烧蚀特性。

| Abstract: | In this paper a preparation technique of fiber-structured W/Cu contact materials is studied, the main properties of the conduct material are measured, and the factors affecting the quality of infiltration are also analyzed. The arc erosion of W/Cu contacts made by powder metallurgy method and the new technique is compared. Results show that the fiber-structured W/Cu contact has better arc erosion resistance than the contact made by powder metallurgy method. |
