Chromium Plating of Caliber .17 (4.32mm) Barrels.
Abstract
Caliber .17 (4.32mm) barrel blanks were machined to the exterior contour of an M16 Rifle barrel. Attempts to chromium plate these barrels with conventional plating fixtures were unsuccessful because misalignment of the electrode caused discoloration and shading of the plating. Attempts to obtain satisfactory, chromium-plated bores by use of better electrode alignment with the conventional fixtures were also unsuccessful. A self-aligning rotating electrode fixture was fabricated, and a technique for chromium-plating the caliber .17 bore was established. With the use of the rotating electrode fixture, many of the problems were eliminated that were encountered with the conventional fixtures on the caliber .17 bore. (Author)
