The multi-component Al–Si–Re–O coating with a thickness of 3.5 μm was deposited on the quartz glass surface by the method of pulsed magnetron sputtering. Its structural phase state and optical and mechanical properties have been investigated. According to X-ray diffractometry and transmission electron microscopy, the structure of the coating is amorphous and has the following elemental composition: Al – 9.29 at.%, Si – 23 at.%, Re – 2.35 at.%, and O – 65.7 at.%. The present work studies the problem of crater formation under the bombardment of the quartz glass surface with Al–Si–Re–O coating by iron particles having a speed of 5–8 m/s. The study discovers protective properties of the Al–Si–Re–O coating manifested as an appreciable decrease of the surface density of the craters formed after impacts of iron microparticles as compared to the uncoated quartz glass. This effect is due to changes in the structure, phase composition, and mechanical properties of the glass surface layer coated by the reinforcing coating. The results show that the quartz glass with the Al–Si– Re–O coating remains transparent in the visible (T ≥ 77%) and UV ranges (T ≥ 23.8%).

采用脉冲磁控溅射方法在石英玻璃表面沉积厚度为 3.5 μm 的多元 Al-Si-Re-O 涂层。对其结构相态以及光学和机械性能进行了研究。根据X射线衍射和透射电子显微镜，涂层结构为非晶态，元素组成如下：Al – 9.29 at.%、Si – 23 at.%、Re – 2.35 at.% 和 O – 65.7在。％。目前的工作研究了铁粒子以 5-8 m/s 的速度轰击具有 Al-Si-Re-O 涂层的石英玻璃表面形成弹坑的问题。研究发现，与未涂层的石英玻璃相比，Al-Si-Re-O 涂层的保护性能表现为铁微粒撞击后形成的凹坑的表面密度明显降低。这种效应是由于增强涂层所涂覆的玻璃表面层的结构、相组成和机械性能的变化所致。结果表明，具有 Al-Si-Re-O 涂层的石英玻璃在可见光 ( T ≥ 77%) 和紫外光范围 ( T ≥ 23.8%) 下保持透明。
