Abstract A number of thermal control coatings were exposed to proton irradiation with particle energies 100–500 keV and particle fluences 1014–2×1016 cm–2 in a proton accelerator. Experimental data on changes of αs of paint coatings and mirror coatings versus the proton fluence and energy are presented. Prediction of the αs changes under the impact of proton radiation with distributed energy spectrum in space flight based on the ground testing results with monoenergetic proton beams is discussed. Estimations of coating degradation in geosynchronous orbit are made using a mathematical model of degradation.
