表面修饰SiO2纳米微粒对锂基脂抗磨性能影响的研究 总被引:9,自引:4,他引:9
合成了表面修饰SiO2纳米微粒,利用四球摩擦磨损试验机考察了SiO2纳米微粒作为锂基脂添加剂的摩擦磨损行为,用扫描电子显微镜、能量色散谱仪和X射线光电子能谱仪对钢球磨损表面进行了分析.结果表明:SiO2纳米微粒作为锂基脂添加剂具有良好的抗磨损性能,能够显著提高锂基脂的失效载荷.这是由于在摩擦过程中,SiO2纳米微粒富集在磨损表面并形成边界润滑膜,对磨损表面起到修复作用,从而使得锂基脂的抗磨和承载能力明显提高. 相似文献

表面修饰In纳米微粒的声化学法制备及结构表征 总被引:3,自引:0,他引:3
Surface modified indium nanoparticles were prepared by a simple and rapid process from bulk indium via ultrasound dispersion. The morphology and structure of synthesized nanoparticles were characterized by TEM, XRD, XPS and FTIR. The results show that the morphology of indium nanoparticles is spherical and the structure of indium nanoparticles is the tetragonal phase. The surface of indium nanoparticles was coated by 2 ethyl hexanoic acid, which could almost hold back oxidation of the indium nanoparticles. In addition, the tribological property of indium nanoparticles as additives in oil was evaluated on a four-ball tester and the results show that indium nanoparticles exhibit good performance in wear. 相似文献
