Abstract:

The acceptance of aluminum for use in ordnance materiel requires the application of a hard-protective coating. Several commercial systems were available for this purpose. The Alumilite 226 Process was selec ed for its comparative simplicity and efficiency. Some modification of he sy em and the use of an independent sensing control circuit produced exceptional re ults relative to growth rate, color continuity, and processing time. The increase in efficiency of the system was a direct result of the sensing circuit and a highly sensitive control design. Reduction in the processing time for the alloys used in the system were 7075-T6, 38 2024-T4, 40 and 6061-T6, 25. The application of the coating o e copper-silicon bearing alloys was accomplished without fear of component dissolution. A technique, which included a slow break-in period with a progressive mperage approach, was developed to process the sensitive copper-silicon alloys.
