【摘要】 文章通过加载不同的线速度和电流研究了Cu-0.8Cr-0.14Zr-0.06Mg合金的电滑动磨损性能,并运用金相显微镜和扫描电子显微镜等仪器对合金滑动磨损表面形貌及磨损机理进行了观察和分析。结果表明,经过920℃×30min固溶,450℃×3h时效处理后,合金的磨损量与运行线速度成线性关系,磨损机理为粘着磨损和磨粒磨损。加载电流后,磨损机理变为粘着磨损、磨粒磨损和电弧诱导磨损。并且随着电流的增大,粘着磨损和电弧诱导磨损变得越来越严重。更多还原

【Abstract】 The electrical sliding wear of the Cu-0.8Cr-0.14Zr-0.06Mg alloy are studied by loading different lining speed and electric current in this article.The alloy sliding worn surfaces and wear mechanism are observed and analyzed by optical microscopy and SEM.The results show that the alloy solved at 920 ℃ for 30 min and aging at 450 ℃ for 180 min behaves a linear relationship between the wear volume and running speed,and the wear mechanism is adhesive wear and abrasive wear.The wear mechanism becomes adhesive wear,abrasive wear and arc induced wear after loading current.And as the current increases,the adhesive wear and arc induced wear is becoming increasingly serious.更多还原
