Abstract
Abstract Electroplating a metal surface which has previously been, or is thereafter peened with high velocity, microscopic, spherical glass bodies to produce microscopic craters thereon, and optionally, removing a portion of the plating so peened by dissolving same with acid. By plating an already peened surface with a reflective material, the zone and/or intensity of reflectivity of the plated surface is increased and/or controlled.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
31 words
A method in accordance with claim 1 wherein the first step comprises electroplating a metal having a higher negative potential in the electromotive series than metal on which it is plated.
Claim 2
Dependent Claim
18 words
A method in accordance with claim 1 wherein said first step comprises electroplating zinc on a steel surface.
Claim 3
Dependent Claim
30 words
A method in accordance with claim 2 wherein the particulate pEening bodies are between 0.005 and 0.03 inches in diameter and the zinc coating is at least 0.0005 inches thick.
Claim 4
Independent Claim
75 words
A method of treating a metallic surface which comprises the separate steps of first peening said surface with microscopic substantially particulate spherical peening bodies entrained in a gaseous fluid having a velocity of at least 2,600 feet per minute directed at said surface whereby microscopic craters are created in said surface and then electroplating said surface with a further metal substantially thicker on the rims of said craters than at the bottoms of said craters.
Claim 5
Independent Claim
99 words
A method of producing a reflective metallic surface which comprises the steps of first peening said surface with microscopic substantially particulate spherical peening bodies entrained in a gaseous fluid having a velocity of at least 2,600 feet per minute directed at said surface, to produce continuous microscopic craters on said surface and then plating said surface with a reflective metal substantially more thickly on the rims than in the lower portions of said craters whereby the depths of said craters from their lower portions to their rims are increased and the angle of reflectivity of said surface is increased.
Claim 6
Dependent Claim
16 words
A method in accordance with claim 6 wherein said plated surface is a plated chrome surface.
Claim 7
Dependent Claim
68 words
An electroplated article having a novel metallic surface, said article comprising a base metal and a further metal electroplated thereon, said base metal having microscopic craters, said electroplating extending over said base metal including the rims and at least in part over the lower portions of said microscopic craters, said plating being substantially thicker on the rims of said craters than in the lower portions of said craters.
Claim 8
Dependent Claim
18 words
The article of claim 8 wherein said base metal is exposed in the bottoms of said microscopic craters.
Claim 9
Dependent Claim
29 words
The article of claim 8 wherein said metallic surface produced by said electroplating has a greater angle of reflectivity than that of the base metal prior to being electroplated.
