Matrix Ceramic Bearings

Application examples for metal ceramic composites also called metal matrix composites mmc are cylinder sleeves in engines tribology piston recess walls tribology brake pad backing plates weight bearings thermal expansion brake discs tribology sporting.

Matrix ceramic bearings.

Ceramic matrix composites are used in higher duty conditions in terms of contact pressure surface speeds and fluid lubricity. Influence friction and wear tribology influence thermal expansion. Few experiments were also performed with flat substrates such as small disks of graphite sic or silica in order. This includes ceramic bearings cutting tools extrusion dies valves sealing rings and cylinder liners etc.

The objectives of the technical and application specific structure design for such ceramics include. In this process a fiber architecture which can be either a simple fiber tow or a multidirectional fiber preform is chemically coated with a ceramic interphase such as c b or bn and then densified with a ceramic matrix such as sic or a multilayered sic based matrix containing boron bearing species in a hot wall deposition chamber from appropriate gaseous precursors. Especially ceramics could be the best suitable material in those tribological applications with high load and precision requirement or corrosive environment such as turbopump in space engine total knee joint replacement and hip.
