采用往复摩擦磨损试验机研究了磷酸盐激光玻璃与石英玻璃球在干、湿空气中的摩擦磨损行为。结果表明，磷酸盐激光玻璃在潮湿空气中的耐磨性优于在干燥空气中的耐磨性，应力腐蚀不会加速磷酸盐激光玻璃的材料去除。磷酸盐激光玻璃表面的赫兹裂纹在潮湿空气中比在干燥空气中更容易形成，而在潮湿空气中，在高负载下，裂纹变得相对轻微。石英玻璃球在潮湿空气中的磨损深度和体积均大于在干燥空气中的磨损深度和体积，表明应力腐蚀对石英玻璃球在潮湿空气中的磨损起主导作用。
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.
