    • Abstract
  • Micro-textures of dimples were produced on the surfaces of Al2O3/Mo self-lubricating structural ceramics using laser surface processing. Taking surface textures as storage of solid lubricants, a three-dimensional lubricating layer was further prepared on the textured surfaces of Al2O3/Mo composites by burnishing mixed lubricants. The synergistic lubrication of mixed lubricants burnished on the textured surfaces of Al2O3/Mo composites from room temperature to 800 ℃ was investigated, and the lubrication mechanism was discussed by analysis of the worn surfaces. Results show that the lubricating layer combined excellent tribological properties of solid lubricants and special structure characteristics of micro-textures, which reduced the friction coefficients at room temperature and moderate temperature and further achieved continuous lubrication over a wide temperature range. The friction coefficients of surfaces burnished with Graphite/BaSO4/CaF2-BaF2 were lower than 0.45 from room temperature to 800 ℃.
