Fabrication Of Electroless Nickel-Plated Mirrors On Alnico Substrates

Spherical metal mirrors have been fabricated by grinding and polishing the desired curvature in electroless nickel deposited over copper electroplated directly on the surfaces of Alnico magnets. Several different electroless nickel plating solutions were investigated, along with a variety of masking materials. Through careful selection of materials and refinements in technique a satisfactory fabrication procedure was developed.
