摘　　要：在往复式摩擦磨损试验机上采用石英玻璃球作为对摩副,研究了干燥和潮湿空气下磷酸盐激光玻璃的磨损性能。结果表明:磷酸盐激光玻璃在潮湿空气下比干燥空气下表现出更好的耐磨性,应力腐蚀几乎不能促进该玻璃的材料去除。此外,低载磨损时磷酸盐激光玻璃在潮湿空气中比干燥空气中更容易出现Hertz裂纹,然而高载下该玻璃表面的Hertz裂纹在潮湿空气中却表现得更为轻微。与磷酸盐玻璃相反,石英玻璃球在潮湿空气下的磨损程度远高于干燥空气下,应力腐蚀对潮湿空气下石英玻璃球的磨损起到了主导作用。The wear behavior of phosphate laser glass against silica glass ball in dry and humid air was investigated by a reciprocating tribometer. The experimental results indicate that phosphate laser glass has a better wear resistance in humid air than that in dry air, and the stress corrosion cannot accelerate the material removal of phosphate laser glass. The Hertz cracks on the surface of phosphate laser glass form more easily in humid air rather than in dry air at a low load, while the cracks become relatively slight in humid air at a high load. The wear depth and volume of silica glass ball in humid air are greater than those in dry air, indicating that the stress corrosion has a dominant effect on the wear of silica glass in humid air.
