A RESEARCH INVESTIGATION OF POSSIBILITIES FOR OBTAINING HOT-HARD ELECTRODEPOSITED CHROMIUM OR CHROMIUM-BASE ALLOYS FOR CANNON

Abstract

A hot-hard Cr-Fe alloy deposited on the bore surface of an erosion-gage weapon insert showed no sign of deterioration after 50 rounds of test firing. The rate of plating was about 0.001 in./hr for a cathode current density of 100 amp/sq ft. Cracking, which appeared in plates applied at 150 amp/sq ft or more, indicated a shift from tensile to compressive stress in the plate. (See also AD-11210)
