Abstract:

The research objective was to establish a method for occulding micron-sized particles in a chromium electrodeposit for use in small arms weapon systems for resistance to high temperature and gas erosion. Two techniques were used for occluding particles of boron carbide, silicon carbide, glass frit, zirconium oxide, aluminum oxide, and diamond dust in standard chromium electrodeposits. The first involved the reliance upon the random occulsion of mechanically dispersed particles in the plating solution. The second involved the use of particles plated with a ferromagnetic coating and a magnetic cathode for magnetic attraction of the particles from the chromium-plating solution to the cathode.
