High Temperature Tribology and Solid Lubrication of Advanced Ceramics
The high-temperature friction and wear characteristics of different ceramics and ceramic matrix composites (CMCs) incorporated with various solid lubricants have been investigated from room temper-ature to 1000℃.The solid lubricants considered in this paper include representative precious metals,hexagonal boron nitride,graphite,fluorides,soft oxides,chromates,sulfates,and combinations of various solid lubricants.General design considerations relevant to solid lubrication were proposed on the basis of friction and wear data of self-lubricating CMCs.The self-lubricating composites incorporated with SrSO4 or/and CaSiO3 exhibits low and stable friction coefficients of 0.2 to 0.3 and small wear rates in the order of 10-6 mm3/Nm from room temperature to 800℃.The optimized composites appear to be promising can-didates for long-duration,extreme environment applications with low friction and small wear rate.
