Abstract The objective of this research was to calibrate the ground-to-space effective atomic oxygen fluence for DC 93-500 silicone in a thermal energy electron cyclotron resonance (ECR) oxygen plasma facility. Silicones, a commonly used spacecraft material, do not chemically erode with atomic oxygen attack like other organic materials. Silicones react with atomic oxygen and form an oxidized hardened silicate surface layer. Therefore, the effective atomic oxygen fluence in a ground-test facility should not be determined based on mass loss measurements, as they are with organic polymers, such as Kapton, a polyimide.
