Abstract
The invention provides a method for enhancing the atomic oxygen corrosion resistance of a paint film. The method for enhancing the atomic oxygen corrosion resistance of the paint film comprises the following concrete steps: firstly, cleaning the surface of the paint film for 1-10 minutes by adopting an ion source; and secondly, plating a transparent oxide thin film on the surface of the paint film, wherein the plating step is implemented by carrying out sputtering deposition of the transparent oxide thin film on the surface of the paint film in three times at different sputtering rates, a first deposition rate is controlled to be 1-2nm / min, a second deposition rate is controlled to be 2-5nm / min, and a third deposition rate is controlled to be 2-5nm / min. The method for enhancing the atomic oxygen corrosion resistance of the paint film has the advantage that the atomic oxygen corrosion resistance of the paint film is enhanced without influencing colours or patterns of the paint film.
Description
technical field [0001] The invention relates to a method for strengthening a paint film against atomic oxygen erosion, which belongs to the technical field of thin films. Background technique [0002] Atomic oxygen is the main component of the atmosphere in the low earth orbit environment. It has strong oxidizing properties, and it will have a serious oxidation and denudation effect on the surface materials of satellites. It is the main factor for the degradation of the performance of satellite surface materials. However, the intrinsic properties of spacecraft surface materials are different, and the requirements for protection methods are also different. The basic principle of atomic oxygen protection is that the protective material or protective coating should not only improve the atomic oxygen resistance of the base material, but also not change the original function of the base material. The present invention is aimed at the special situation of atomic oxygen protection...
