MISIS specialists have developed a promising coating to protect satellites
Researchers at MISIS University in Russia have developed unique coatings that offer enhanced protection for spacecraft components, particularly solar panels and optics. Here are the key features of these coatings:
-
Enhanced Resistance: The coatings are designed to provide up to 5 times greater resistance to external influences, such as space debris and micrometeoroids, than existing materials. This increased durability is crucial for the longevity and safety of spacecraft in orbit.
-
Optical Transparency: The coatings maintain optical transparency, making them suitable for use on solar panels and visual components of spacecraft. This transparency is essential for the proper functioning of these devices.
-
Tantalum-Based Layer: The coatings feature a layer composed of tantalum with silicon and nitrogen (Ta-Si-N). This layer helps mitigate the adverse effects of small particles and micrometeoroids on spacecraft modules.
-
Unique Qualities: Ta-Si-N coatings are notable for their combination of qualities, including wear resistance, high optical transmittance, thermal stability up to 1200°C, and oxidation resistance. These properties make them ideal for space applications where extreme conditions are encountered.
These coatings represent an essential advancement in protecting spacecraft and their vital components from the hazards present in space, including space debris and micrometeoroids. They offer enhanced durability and optical transparency, ensuring the spacecraft’s continued functionality and safety in orbit.
