| Objective To study the irradiation effect of atomic oxygen (AO) on stainless steel. Methods AO irradiation test of stainless steel was conducted using an AO simulation facility with AO flux of 2.5×1016 atoms/cm2·s and the maximum irradiation time was 300 min. The variations of mass, optical property, contact angle, wear resistance and corrosion resistance of the specimens with prolonged irradiation time were investigated. Results After AO exposure, metal oxides were found on the surface of stainless steel, leading to increase of sample mass. The spectrum reflectance of copper decreased with the increasing irradiation time, while the solar absorption ratio showed the opposite trend, which increased with increasing irradiation time. In addition, AO irradiation resulted in the increase of contact angle and wear resistance property, and meanwhile decrease of corrosion résistance property. Conclusion AO effect data of stainless steel was obtained, which can provide theoretical support for the application of stainless steel in low earth orbit spacecraft. |
