采用正交试验方法优化受电弓滑板的制备工艺,通过测试滑板的冲击性能、电阻率、磨损性能,确定其最佳制备工艺;利用电子探针对磨损后的表面进行了观察,并分析了受电弓滑板的磨损机理.结果表明,受电弓滑板的主要磨损形式是粘着磨损及磨粒磨损,模压温度和加压时机对滑板的综合性能影响较大.分析得到最佳制备工艺参数为:模压温度T=170℃,单位厚度保压时间t=5min/mm,压力P=60MPa,加压时机t_p=3min.
Orthogonality experiment method is used to optimize the manufacture process of pantograph slide plate. The best preparation technology is determined by testing the impact toughness, resistivity and wear resistance of the slide plate. The morphologies of the worn surfaces are observed with electron probe, and the wear mechanics are analyzed. The results show that adhesion wear and abrasive wear are the main wear of pantograph slide plates. The most important factors that greatly influence the properties of pantograph slide plate are molding temperature and holdup time, and the best process parameters are as follows: molding temperature T=170℃, holdup time t= 5min/mm, pressure P=60MPa, pressure time t_p=3min.
