The shortcomings encountered with conventional high contraction chromium coatings in gun bores during past investigations are reviewed. Changes in the application of chromium for improving its performance during firing are proposed. Recent developments on the application of low contraction chromium with a new plating process, effects of partially plated bores on accuracy, and the effects of rifling profile on the wear of chromium coatings are discussed.
