Abstract : Chromium plating of small arms barrels results in longer accuracy life. However, the cost of plating is excessive compared to the results obtained. The plating of 37 mm gun barrels to date has been unsatisfactory. The chromium plating of 3 in. A.A. gun tubes has been successful insofar as the technique of plating is concerned, but the expected increase in accuracy life has not materialized. The use of chromium plating generally for gun barrels is not economical.
