Study on Inorganic Coating of Porous Nitride Radome

Abstract:

The surface of porous nitride radome became very compact by AlPO₄-Si₃N₄-SiO₂(n) coating treatment. Coating could immerse into the matrix about 20μm deep. This could also make material be moisture resistance for long time placement. Coating effectively healed the micro cracks on the matrix and combined with it by crossed occlusion, so the strength and the fracture toughness of material increased.
