| 摘 要： | 选用TiO2作为触头材料的添加剂，采用粉末冶金法制备了6种不同第二相（SnO2）粒度的AgSnO2和AgSnO2/TiO2触头材料。研究了2种触头材料的润湿性和电接触性能。用座滴法测量了Ag与SnO2之间的润湿角，并表征了材料的湿润性，使用JF04C电接触触头材料测试系统对材料电接触性能进行了测试，分析了不同第二相粒度的触头材料的润湿性和电接触性能的变化规律。结果表明，当第二相粒度为100~300 nm时，2种触头材料的性能均优于其它粒度的触头材料。

| Abstract: | TiO2 was selected as the additive of the contact material, and AgSnO2 and AgSnO2/TiO2 contact materials with six different particle sizes of second phase (SnO2) were prepared by powder metallurgy. The wettability and electrical contact properties of both contact materials were studied. The wetting angle between Ag and SnO2 was measured by the sessile drop method, and the wettability was characterized. The JF04C electrical contact material testing system was used to test the electrical contact properties, and the change laws of wettability and electrical contact performance of contact materials with different particle sizes of second phase were analyzed. The results show that the properties of the two contact materials with the particle size of second phase ranging in 100~300 nm are better than those with other particle sizes. |
