在MHK－500型环块摩擦磨损试验机上，研究了纳米级金属镍粉（直径在10～50nm）加入到矿物油中的润滑性能，结果表明：在低中滑动速度下（滑动速度分别为1．285m／s和2．57m／s），加有纳米级镍粉的润滑油表现出优良的抗磨性能．
In MHK-500 ring block friction and wear testing machine, studied the nano-nickel metal powder (diameter 10 ~ 50nm) added to the mineral oil in the lubricating properties, the results show that: in the low sliding speed (sliding speed of 1 .285m / s and 2.57m / s), plus nano-nickel powder lubricant showed excellent wear resistance.
