Factors Affecting the Electrodeposition of Paints on Aircraft Alloys,
Abstract
The report summarises a program of experiments concerned with the electropainting of aluminum alloys and magnesium alloys. It is shown that, in the case of aluminum, anodising is a precursor to paint deposition. A system is described whereby aluminum alloys may be electropainted with a low (100C) temperature curing system which contains a chromate pigment, and which imparts good salt spray resistance. The advantage of the system in penetrating crevices in complex structures and assemblies is demonstrated. Also described are methods of: electropainting magnesium alloy to provide a finish with a measure of salt spray resistance; and, electropainting relatively deep holes in magnesium castings with a paint layer of controllable thickness (0.5 plus or minus 0.1 mil).
