金刚石纳米颗粒对薄膜润滑性能的影响
INFLUENCE OF DIAMOND NANO-PARTICLES ON THE TRIBOLOGICAL PROPERTIES OF THIN FILM LUBIRCATION
【摘要】 采用相对光强原理对超细金刚石粉添加剂的纳米摩擦学性能进行了研究。试验结果表明 :在薄膜润滑区 ,球型纳米金刚石颗粒的增粘作用 ,使混合油油膜增厚 ;微滚动效应则导致摩擦力减小。其摩擦过程是金刚石颗粒不断分散和团聚的过程 ,呈现时间效应
【Abstract】 Using a technique of relative optical interference intensity (ROII), the nanotribological properties of ultrafine diamond powder as additive is investigated. Results have shown that the effect of viscosity of global diamond nanoparticles gives rise to thicker film in thin film lubrication regime. Its effect of tiny ball bearing leads to a lower friction coefficient. The tribological process is one that the ultrafine diamond powder is dispersed and reunited continuously and exhibits time effect.
