with electrical current. As shown in Table 4, the oxygen contents of the electrical erosion pits and wear debris increase with the increase of contacting temperature and testing time, achieving about 12.65... Tribological behavior and wear mechanism of resin-matrix contact strip against copper with electrical current TU Chuan-jun(涂川俊), CHEN Zhen-hua(陈振华), CHEN Ding(陈 鼎), YAN Hong-ge(严红革), HE Feng-yi......
3D continuous ceramic network against Cr12 steel was studied with oscillating dry friction and wear tester under the testing conditions of 70 ℃, 30 min, and the load range of 40-100 N. The experimental...; therefore, the wear area on composite sample was 15 mm×8 mm. Pre-wearing was conducted for 5 min before the formal testing. Wear depth in worn region was measured by 3D profiler. On the worn area of 5......
°C for 1 h. The samples were then weighed to an accuracy of 0.1 mg. The friction and wear tests were carried out on a MRH-1A (Yihua Tribology Testing Technology Co., Ltd China) wear tester using...J.
