on the counterpart surface due to the interaction of furan resin and wear debris of graphite, which was useful to reduce the wear rate of the resin/graphite composite. The composite is highly promising...Friction and Wear Behavior of Resin/Graphite Composite under Dry SlidingZhenguo Zhu,Shuo Bai,Junfeng Wu,Li Xu,Ting Li,Yong Ren,Chang LiuShenyang National Laboratory for Materials Science, Institute......
on itself were investigated in air at room temperature.The experimental results demonstrated that the wear rate of the material decreased with the increase of the wear time.The friction coefficient fluctuated severely when the applied load was 120 N.At 120 N the wear rate was much higher than that of the applied load of 70 N.At 70 N the wear rate did not show much difference from that of 30 N.The wear......
Research About Microstructure and Wear Resistance of Hardfacing Layer on Cast Iron LI Guo-qing1,HE Bo-lin1,YU Ying-xia1 (1.College of Mechanical & Electrical Engineering, East China Jiaotong University, Nanchang, 330013, P. R. China) 摘要:It''s simple technology to manufacture big trimming die by hardfacing on the base metal of cast iron. The chemical composition, microstructure, hardness, wear......
and the creep rate method are combined to anti-skid, the wheel wear gradually increases as the speed decreases, and increases first and then remains constant as the creep rate threshold increases. The creep rate threshold corresponding to the remained wear increases as the speed decreases. It is recommended that the creep rate threshold can be optimized in other ways after the wheel wear remains......
show that hydrogen decreases the wear resistance of Ti6 A14 V alloy. Wear rate of the Ti6 A14 V alloy increases after hydrogenation. Wear rate increases by 244.3 % when 0.5 wt% hydrogen is introduced into a Ti6 A14 V alloy. Wear rate of the dehydrogenated Ti6 A14 V alloy recovers. Wear mechanisms of the nonhydrogenated, hydrogenated, and dehydrogenated Ti6 A14 V alloys are determined......
-bearing capacity and wear resistance of the intermetallics, as evidenced by an increase of scuffing load up to 4 times and a wear rate reduction of two orders of magnitude. The coefficient of friction has also been reduced from 0.5-0.7 for the untreated to an average of 0.22 for the CC-treated alloy under dry sliding contact conditions. 关键词:titanium aluminides; wear resistance; sliding wear......
in Mg-10Y-4Gd-1.5Zn-0.4Zr alloy plays an important role in the wear rate. Key words: Mg-Y-Gd-Zn-Zr alloy; sliding wear; wear rate; wear mechanism; hypereutectic Al-Si alloy 1 Introduction Magnesium and its... magnesium alloy and tool steel is very low compared with that between 5083 aluminium alloy and tool steel. The wear rate of AZ91D magnesium alloy is lower than that of AS21 aluminium alloy against......

Self... difference, which resulted in the change of wear rate. And the relationship among micro-hardness, average grain size and wear rate of the track had also been investigated. Subsequently, an optimization......
