摘要
采用块 -块摩擦磨损试验机在不同磨粒的 5 %NaOH泥浆中 ,对氧化铝增强四方氧化锆多晶陶瓷材料 (ADZ)的磨损性能进行了研究。研究结果表明尖锐磨粒对ADZ复合陶瓷材料磨损的影响要比球形磨粒严重的多 ,磨料硬度是影响陶瓷材料磨损率的重要因素 ,磨损率随磨粒硬度的提高而增大。在不同形状的SiO2 磨粒的泥浆中ADZ陶瓷材料的主要磨损机理为塑性变形和微犁削。在高硬度Al2 O3磨料的泥浆中ADZ陶瓷材料磨损表面以断裂机制占主导地位。
The wear properties of alumina reinforced Y-TZP composites in 5% NaOH slurry containing different abrasive particle were investigated using a block-on-block friction and wear test apparatus. The results showed that the effect of sharp abrasive particle on the wear rate of ADZ was more than that of the round particle, the hardness of the abrasive particle played an important role on the wear rate, and the wear rate was increased with the increase of the hardness of abrasive particle. The main wear mechanism of ADZ composites in the slurry containing different shape SiO2 particles was plastic deformation and microcutting, but the removal of material was controlled by fracture in the slurry containing the hard particles.
