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.
Key words:
Thin film
lubrication Ultrafine diamond powder Effect of tiny ball
