Abstract

According to the requirements of the military optoelectronic system for the application of the reflector, optical processing experiments were carried out on the SiC_p/Al coating nickel phosphorus alloy plane mirror; The optical properties of the SiC_p/Al and several commonly used optical materials were compared; The turning test and polishing test of uncoated nickel-phosphorus and nickel-phosphorus-coated aluminum-based silicon carbide were carried out, the optical processing of φ150mm SiC_p/Al coating nickel-phosphorus alloy plane mirror was realized, and the high quality and high precision optical surface was obtained. The RMS value of surface accuracy was 1/27λ(λ=632.8nm), The surface roughness Ra was better than 3.3nm, which confirmed the feasibility of using SiC_p/Al composites in military optoelectronic systems and met the requirements of precision of the reflector.
