英文摘要

High-performance alumina matrix ceramics have potential applications in harsh environments such as corrosive and high-temperature conditions because of their excellent mechanical properties, corrosion-resistance, and oxidation stability. In this study, a 3-D lubrication structure was designed and prepared on the surface of Al2O3/Ni-laminated ceramics using laser surface texture technology and bonded PTFE coatings. The wear mechanisms of the materials were also studied, and the effects of the 3-D lubrication structure on the tribological properties of Al2O3/Ni-laminated ceramics under dry and aqueous conditions were investigated. Four types of microdimples with different diameters and bonded PTFE solid lubricating coatings were successfully prepared on the surface of Al2O3/Ni-laminated ceramics. Experimental results demonstrated that the bonded PTFE coating combined with micro-dimples on the surface of ceramics had excellent load-carrying capacities and wear-resistance
under both dry and aqueous conditions. The wear life showed a marked increase under both dry and aqueous conditions because the solid lubricant that was embedded in the micro-dimples improved the bonding
strength of the coating and provided secondary lubrication. The synergistic effects of the micro-texture and the bonded PTFE coating significantly improved the tribological properties of the materials.
