Studying the Ultimate Strength and Service Life of Quartz Glass with Protective Coating for Space Vehicle Windows
摘要
The paper focuses on the impact of an optically transparent protective coating of an AlSiN system on the short-time ultimate strength of quartz glass discs as delivered and after crater damage by impact particles simulating micrometeoroids. The statistical processing of the data discovers a negative correlation between the specimen ultimate strength and the crater damage. This allowed assessing the residual average and assured lifetime of coated space vehicle glass windows.
