Abstract
Si3N4-based ceramics were recently used for machining cast iron at very high speeds.However,they were found to be unsuitable for machiningsteels because of the severe wear ofthe ceramic. In sliding contacts.The tests were carried out on a pin-on-disk tribometer. The test results showed that the lubricants containing additives could effectively reduce the friction and wear of Si3N4 ceramics. The between the rubbing surfaces. The element interdiffusion and adhesion between the rubbing surfaces were prevented or greatly reduced.
