In this paper, ZrO2 matrix high-temperature self-lubricating composites with addition of CuO as lubricant were prepared using a hot-pressing method by tailoring the content of CuO. The wear and friction behaviour of the composites were investigated from 700 degrees C to 1000 degrees C. The composites sliding against an Al2O3 ceramic ball exhibited excellent self-lubricating and anti-wear properties at high temperatures. The low friction and wear mechanisms were investigated in detail. (C) 2013 Elsevier Ltd. All rights reserved.
