Composites as Lubricants for Ceramics

Development of new solid lubricants is underway. Nanocrystalline lubricant particles embedded in hardcoating material will allow low friction and increased durability of mechanisms in sliding contact. Special attention is being given to materials used in prosthetics including hip implants, where release of wear debris is detrimental. Other uses for low friction nanocomposite coatings include high temperature service or use in vacuum. Nanocomposites formed by unique methods will minimize wear resulting in increased survivability of frictional contacts. Ceramics in contact with ceramics, metals, or polymers will benefit greatly from advanced deposition methods yielding novel microstructures with a synergistic action among the constituent phases. Areas expected to profit from this technology include biomaterials, aerospace applications, and automotive technology including ceramic engines and turbines.
