On-line tribochemical strengthening of gear surface

It has been found that under favorable friction conditions some antiwear el ements in lubricating additives can permeate into subsurface of metal which can strengthens the friction surfaces and improves anti-wear capacity of f rication pairs. It is in many ways similar to chemical heat treatment. A ne w concept, technology of on-line strengthening, was logically put forward. Based on current gear surface treatment technology, the on-line strengthen of gear surface is proposed. Its design method is established. Based on it, the on-line strengthen of gear is achieved on CL-100 gear test machine. A new method is put forward for strengthen treatment of gear surface. And thr ee kinds of surface film were suggested.
