they were fabricated by Bell Telephone Laboratory. The mechanical and wear-resistant properties of Cu-Ni-Sn alloy are close to those of Cu-Be alloys [1]. Therefore, Cu-Ni-Sn alloys are considered substitutes... of Ni content and hardness on the wear behaviour of sand cast Cu-Ni-Sn alloys [J]. Intemational Journal of Microstructure and Materials Properties, 2012, 7(4): 316-328. DOI: 10.1016......
Influence of loading and rotation speed on Friction and Wear properties of CuAlBi Alloy Dong Litao1,Li Xingyuan2,Liu Rongchang1,Chen Xiuhong1 (1.E & A College, Hebei Normal University of Science... and rotation speed on friction and wear properties of CuAlBi alloy was also discussed. The results show that the friction coefficient increase then decrease with increase of connecting loading......
Microstructures and wear properties of graphite and Al2O3 reinforced AZ91D-Cex composites ZHANG Mei-juan(张美娟)1, 2, CAO Zhan-yi(曹占义)1, YANG Xiao-hong(杨晓红)1, LIU Yong-bing(刘勇兵)1 1. Key Laboratory... dispersed uniformly and no agglomeration and casting defect were observed. The microstructures and wear properties of the composites with different Ce contents of 0, 0.4%, 0.8% and 1.0%, respectively......

properties of MoSi2 against Al2O3 were investigated by using an XP-5 type High Temperature Friction and Wear Tester. Micrographs and phases of the worn surface of MoSi2 were observed by SEM with EDS and X-ray... as the friction disk. The properties of the friction pair materials are listed in Table 1. Every wear test was done at the sliding speed of 0.126 m/s. Test loads were selected to be 10, 20, 30, 40, 50 and 60 N......
various conditions. In recent years, many domestic and foreign researchers have investigated the wear properties of the drum. The works include the load distribution of the drum when the coiler...]. But the wear of the drum is not only related to the inherent properties of the material but also has a closed relationship with the comprehensive performance of tribological system. So far......
). The results show that the wear properties of the samples undercooled by 80K and 310K are obviously superior, which is attributed to more efficient transfer of Pb from the bulk material to the worn...Tribological property and wear mechanism of undercooled Ni-Pb monotectic alloys XIE Hui(谢 辉)1, YANG Gen-cang(杨根仓)1, HAO Wei-xin(郝维新)1, LA Pei-qing(喇培清)2, LIU Wei-min(刘维民)2, XU Li-jun(许丽君)1......
