| Abstract: | The electron irradiation ground simulation test was conducted on the ITO/F46/Ag thermal control coating. The variation of surface resistivity of the ITO/F46/Ag coating with electron fluence was discussed, and the scanning electron microscope was used to analyze the irradiation effects of electron on the coating’s morphology. It was found that there were severe damages appearing in the ITO/F46/Ag coating, e.g. crack, debris and melt erosion. The damage mechanism of the ITO/F46/Ag thermal control coating under electron irradiation was analyzed, and a surface damage model was proposed. |
