. And the linear wear rate of the C/SiC modified with graphite was lower than that of the C/SiC unmodified. Key words: 3D needled C/SiC; brake material; microstructure; frictional properties 1 Introduction... point of silicon, which led to unstable frictional properties and adhesive wear. In this work, a C/SiC brake material modified with graphite is reported to minimize content of the free silicon......

load of 700 N and a sliding speed of 2.32 m/s condition was forced to stop because the instantaneous frictional torque reached the maximum friction torque of the wear tester (4000 N·m). The friction... lower with increase in sliding time owing to the generation of frictional heat, resulting in thin lubrication film. Wear debris generated by rubbing and micro-cutting of hard asperities might......
Preparation, Characterization and Frictional Properties of Silane Self-Assembled Elastomeric Nanocomposite Polymer Layers程广贵,丁建宁Center of Micro/Nano Science & Technology, Jiangsu University摘 要:
on the surface and in the grooves. Generally, under dry friction conditions, the abrasives on the surface form the "three-body friction" easily which will increase the frictional coefficient and induce the wear... on the untextured surfaces (Figure 9(a)) than on the textured surfaces (Figure 1), which resulted in the high frictional coefficients and serious wear tracks for untextured samples (Figure 9(b)). In comparison......
the wear process, so the wear rate of as-cast alloy is higher than that of cast+T6 alloy, as shown in Fig. 2. With increasing sliding speed, the generated frictional heat gradually affects the wear... Trans. Nonferrous Met. Soc.
