摘　　要：采用粉末冶金工艺研制成Ａｇ－ＣｕＯ（１０）触头材料。结果表明：产品密度达９．６２～９．７ｇ／ｃｍ３，硬度ＨＢ７５０～８６０，电阻率２．２５～２．３９μΩｃｍ，抗弯强度３７０～４２０ＭＰａ；２００万次机械寿命和７周期交变湿热试验均能满足电力机车的使用要求。此外。The contact material of Ag CuO prepared by P/M was investigated. The results showed that its density is 9.62￣9.7 g/cm 3, hardness HB 750￣860 MPa, electric resistivity 2.25￣2.39 μΩ·cm, TRS 370￣420 MPa; and it can sustain 2 000 000 times of machine life span tests and 7 cycles of thermohygrometric exchange tests, verifying that it meets the electric locomotives demands; besides, Ag CuO 10 may be used instead of Ag CdO 15 contact on the contactor of low pressure electrical equipment.
