但是后来,1892年他在波恩大学做赫兹的助手时,赫兹让他观察了他的新发现,赫兹将一片盖上铝箔的含铀玻璃片放入放电管,当用阴极射线轰击铝箔时,铝箔下面发出了亮光。

The results under the oil lubricate friction conditions were similar with those under the dry friction conditions. The wear mechanism of 3Cr13 matrix alloy was micro-cutting and distorting wear. For the composites with a low fraction of TiC particle, distorting wear dominated and cutting was partly operating. For the composites with a high fraction of TiC particle, stress fatigue wear and wear of hard phase decohesion has occurred, but the main wear mechanism was still distorting wear. When the wear experiments were performed under the oil lubricate friction conditions, the main wear mechanism has became to abrasive wear and fatigue wear for the composites with the low TiC fraction, and fatigue wear would be to dominate for the composites with the high TiC fraction. There were similar wear mechanisms in H13 and 1Cr18Ni9 matrix composites.

在干摩擦条件下,3Cr13基体合金的磨损机理为显微切削和变形磨损;低体积分数的复合材料磨损机制以变形磨损为主,兼有少量的切削磨损机制;高体积分数的复合材料磨损机制以变形磨损为主,兼有应力疲劳磨损和脆性相剥落磨损;在油润滑摩擦条件下,3Cr13基体合金的磨损以磨粒磨损为主;低体积分数的复合材料磨损为磨粒磨损和疲劳磨损;高体积分数的复合材料磨损以疲劳磨损为主。H13、1Cr18Ni9基体及其复合材料的磨损机制类似于3Cr13基体及其相同体积分数的复合材料。
