Abstract
A metal-infiltrated ceramic for use in tribological applications, such as in mechanical face seals, beatings and other sliding or rubbing components, which provides excellent durability and wear characteristics. The metal-infiltrated ceramic is useful in both the “harder” and “softer” one of two relatively sliding members which is in, or may come into, contact with each other during the motion of one of the members relative to the other. The material is a porous ceramic which has been infiltrated with a metal.
