摘要
采用原位合成法制备Cu-Cr-Zr合金,并对时效试样进行显微硬度、电导率及耐磨性能测试,研究结果表明,80%冷变形处理后最大电导率比初始电导率提高约一倍,变形量越大,合金的电导率越高,冷加工态的试样在500℃以下时效处理时,对导电率的影响十分明显,而对硬度的影响较小。合金材料的磨损试验表明,不带电磨损的机制主要为粘着磨损,带电情况下磨损机制主要为磨粒磨损。
Micro-hardness,electric conductivity and wear resistance of aged Cu-Cr-Zr alloy prepared by in-situ synthesis were examined. The results reveal that compared with that of initial samples,electric conductivity of 80% cold deformed alloy is increased approximately 100%,furthermore,with increasing in deformation rate,the electric conductivity of the alloy is increased. After aged at 500℃ for the cold deformed alloy,electric conductivity is obviously affected,however,change of hardness is absent. Tribological behavior is characterized by adhesive abrasion under current free while it is abrasive abrasion under current conditions.
