英文摘要	Inorganic phosphate coating exhibits great potential applications in extreme environments, it is regrettable that its poor mechanical flexibility limited their scope of application. This paper aims to provide a new way to improve the flexibility of phosphate coating by using polytetrafluoroethylene (PTFE) as the dopant. The influence of atomic oxygen (AO) irradiation on microstructure and tribological properties of the coatings were then investigated. Results indicated that PTFE molecules embedded into the phosphate networks homogeneously could not only improve the flexibility of the coatings from grade 3 to 1 but also exhibit excellent friction and wear properties under air and vacuum conditions after a long-term AO irradiation. These are due to a continuous phosphate binder phase itself had a good resistance to AO irradiation. Thus, this study is expected to provide a new idea for designing and applying self-lubrication coating materials in extreme space environments.
