粘结MoS2基钼固体润滑膜的抗承载能力和耐速度性能研究EI

为了探讨粘结MoS2基固体润滑膜在干摩擦条件下的抗承载能力和耐速度性能,使用国产的环一块摩擦磨损试验机在干摩擦下对粘结MoS2基固体润滑膜在不同载荷和不同速度试验条件下的摩擦磨损性能进行了研究.试验结果表明:粘结MoS2基固体润滑膜的承载能力有高达2100N,在0.512～3.84m/s的滑动速度范围内具有良好的抗磨减摩性能.对转移膜的研究结果表明高载高速试验条件有利于促进对偶表面生成高质量的转移膜.粘结MoS2基固体润滑膜具有良好的抗承载能力和耐速度性能的机理应归结于在摩擦过程中对偶表面高质量转移膜的生成.

Performance and Test Research of Fluorine-preparing C/C Composites Electrolysis Plank

The C/C composites electrolysis plank that applied to preparing fluorine we produced by carbon fiber perform, pitch infuse and carbonization, resin infuse and carbonization and high temperature treatment processing. Then it was analyzed by mechanics performance, electrical resistivity, thermal performance. At the same time, the C/C composites electrolysis plank was tested in electrobath. The results showed that C/C composites electrolysis plank had high mechanics performance, having perfect tensile strength, compressive strength , flexural strength and shear strength, having excellent anti-corruption, thermal performance and electrical resistivity. It extended life of electrolysis plank and reduced replacing in electrobath. The microstructure was analyzed by SEM. The experiment showed that fracture part was fragile fracture.
