Recent progress and future prospects in the surface engineering and tribology of ceramics
This brief review shows that ceramics have much to offer for demanding tribological applications; however their widespread use in advanced tribosystems will have to wait for effective lubricants. Microfracture and tribochemical/thermomechanical interactions may occur and dominate the wear behavior. Solid, liquid, and vapor phase lubrication approaches have been explored and shown to be effective under certain conditions. Strong adhesion appears to be the most important requirement for a thin solid lubricant film for ceramic surfaces. Ion-beam processes can impart strong adhesion between solid lubricant films and ceramic substrates. For ceramics with poor thermal conductivity, solid lubricants that combine high thermal conductivity and low shear strength and good chemical inertness should be considered. Results from diamond and diamond-like carbon-coated ceramics, and monochalcogenides are also encouraging.
