摘要

The contamination of three types of thermal protective coatings for space application was tested using the decomposition vapors of two types of adhesive. The deposits were controlled with quartz microscales before and after exposition to vacuum only, or vacuum combined with ultraviolet or proton radiation. The optical reflectance evolution was measured. It is concluded that both kinds of irradiation affect strongly the possibility of reflectance recovery after contamination. The results allow a better understanding of the degradation of the solar reflectance of satellite protective coatings.
