Self-lubricating composites

Lubricants. TeUurides of titanium, 2irconium, molybdenum, tungsten, and other refractory metals are heat- and vacuum-stable. This property makes them useful in soUd self-lubricating composites in the electronics, instmmentation, and aerospace fields (see Lubrication and lubricants). Organic teUurides are antioxidants in lubricating oUs and greases. 

Obtain specific properties using, for example, a self-lubricating composite insert. Discontinuous fibre reinforced thermoplastic composites can also be overmoulded onto GMT sheets.

An inorganic solid lubricant has been described as a self-lubricating composite comprising a chromium oxide (e.g. chromic oxide, Cr203), a metal binder comprising Cr/Ni or Cr/Co alloy, a metal fluoride, and, optionally, a metal lubricant [60]. A milled powder mix of the composite is deposited onto a substrate, e.g. by plasma spraying.

Development and tribological evaluation of these self-lubricating composites over the past several years has recently been reviewed by Sutor and Gardos (7, 8). This work demonstrated that many of the composites which were excellent lubricants for steel were poor lubricants for silicon nitride. Thus, achieving effective solid lubrication of silicon nitride was of particular concern.
