A method to prepare high quality SiC coating at low temperature using large aperture E-beam evaporation PVD equipment with ion assistance was developed for the surface modification of SiC mirror for space projects. This method was called Ion Assisted Reactive Evaporation (IARE). The modified SiC coating was prepared using CH4 and Si with Kaufman ion source by IARE at 300C and it had met the requirements of applications. The SiC coating prepared by this method was amorphous. It was dense  homogeneous and easy to be polished. The surface modification of a SiC mirror was carried out using SiC coating by this method and achieved a fine surface modification effect. The surface roughness (rms) of the SiC substrate was reduced to 0.862nm  the scattering coefficient was reduced to 2.79% and the reflectance coated with Ag film was improved simultaneously after the surface modification. The effect of surface modification using SiC coating was close to that of using Si coating. It can be drawn that this technological method to preparation SiC coating for the surface modification of SiC mirror is reasonable and effective. 2011 SPIE.

To eliminate surface limitation caused by Silicon impurity in RB-SiC space mirrors  a relatively thick Si film is deposited on well finished RB-SiC substrate by a new process-ion assisted depositing (IAD) to provide a better polishable surface. Testing results of IAD-Si properties are provided  showing that the amorphous film has great thermal shock resistance. Then  polishing experiments on 100.5m thick IAD-Si layers are accomplished focusing on smoother surface. Surface figure and micro-roughness of the coating after polished reach 0.026 RMS (=0.6328nm) and less than 0.5nm RMS respectively. Moreover  reflectivity of IAD-Si polished surface with reflective films increases higher than 4.5% than that of RB-SiC in 360-1100nm. High reflectivity and desirable thermal property make IAD-Si an attractive coating material for RB-SiC space mirrors. 2009 SPIE.
