Optical Fabrication on High Volume Fraction SiCp/Al Coating Nikel-Cobalt Alloy Paraboloid Mirror
In order to manufacture mirrors with fine mechanical and thermodynamic properties, the fabrication of high volume fraction SiCp/Al coating nickel- cobalt alloy aspheric mirror is studied; the mechanical and thermodynamic properties of high volume fraction SiCp/Al are introduced; then, several kinds of polish agent and model are used in experiments for polishing SiCp/Al coating nickel- cobalt alloy samples; finally, on the basis of experiments, a Φ300 mm high volume fraction SiCp/Al coating nickel- cobalt alloy paraboloid mirror is manufactured. The tested results indicate that surface accuracy of the mirror is 0.027 λ (RMS, λ =632.8 nm), and the surface roughness is 2.1 nm (Ra).
