Through the tribological tests using lubricating oil with Cu nano-powders it was found that along with time a negative wear phenomenon occurred. In general condition the wear is the natural result of rubbing, but our discovery proved that under a special condition the negative wear can be present, and the knowledge about friction and wear will be expanded. The negative wear phenomenon certified the existence of "dynamic self-repairing mechanism ",which will strongly support the development of intellectual self-repairing technology of equipment.
