Abstract

The effect of the thickness of thin protective In-Sn-O coatings, deposited on quartz glass by magnetron sputtering at various partial pressures in an argon and oxygen atmosphere, on their impact resistance and light transmission is studied. A correlation is revealed between the light transmittance in the ultraviolet (UV) region, the surface density of craters formed by hypervelocity bombardment with iron microparticles, and the sizes of the craters on the coating surfaces. The results of bombarding the In-Sn-O/quartz glass targets with a flow of microparticles using a light gas gun show that the UV transmittance of the coatings with different thicknesses (~4 and ~6 μm) increases by up to 12%, while for the uncoated KV quartz glass it decreases from 92% to 54% after bombardment. The number of craters forming on the coating surfaces depends on their thickness: with an increase in the In-Sn-O coating thickness to ~6 μm, the surface area occupied by the craters decreases, while the optical transmittance spectrum of the coatings remains unchanged.

超高速铁微颗粒对带有 In-Sn-O 保护涂层的石英玻璃在紫外线范围内的透光率的影响
研究了在氩气和氧气环境中以不同分压通过磁控溅射沉积在石英玻璃上的 In-Sn-O 薄保护涂层的厚度对其抗冲击性和透光性的影响。紫外线(UV)区域的透光率、铁微粒超高速轰击形成的凹坑表面密度和涂层表面的凹坑大小之间存在相关性。用光气枪用微粒子流轰击 In-Sn-O/ 石英玻璃靶的结果表明,不同厚度(~4 和 ~6 μm)涂层的紫外线透过率增加了 12%,而未涂层的 KV 石英玻璃在轰击后的紫外线透过率从 92% 降至 54%。涂层表面形成的凹坑数量取决于其厚度:随着 In-Sn-O 涂层厚度增加到 ~6 μm,凹坑占据的表面积减少,而涂层的光学透射光谱保持不变。
