Recently we wrote about the destruction in orbit of the Soviet satellite “Kosmos”, which, as presumably, occurred due to the operation with space debris, and mentioned the problem with its image in earth orbit, and now the news has come up about Russian developments in the field of protecting defense apparatus. from debris and micrometeoroids.
More specifically, we are talking about unique coatings created at the University of MISIS that protect salt batteries, as well as optics operating in spacecraft, offering up to 5 times greater resistance to various influences than currently used materials.
It is also noted that the new coating is optically transparent, which is important for solar panels and thin-component optics, specially smooth, soft, treated with cream and nitrogen (Ta-Si-N), will close the problem of negative and dangerous effects on the modules of apparatuses of small particles or micrometeoroids.
In addition, coatings of the Ta-Si-N type are very unique in terms of their set of qualities and, in addition to wear resistance, they offer. They have high optical efficiency at 1200°C and have high thermal stability k. oxidation.
