A Research Investigation of Possibilities for Obtaining Hot-Hard Electrodeposited Chromium or Chromium-Base Alloys for Cannon
Abstract
Experiments were continued on the application of 94% chromium - 6% iron alloy plate to the bore surfaces of cannon. An extended series of tests was unsuccessful in pointing a way for plating full-length gun tubes with moving anodes. Good plate was obtained only at the initial position of the anode. Areas plated after the anode travel began received a poorly adherent plate. The plating solution etched these areas before plating began, and the effect of the etching was to prevent plate adherence. Several erosion-gage weapon inserts were plated using full-length stationary anodes. Firing tests showed these plates to lack sufficient adherence for erosion resistance. However, the full-length anode system offered advantages over a moving anode. Plating tests were begun with four-foot lengths of simulated smooth-bore 40-mm gun tubes. These tests had not reached a conclusive stage when the contract period ended. Additional keywords: U/A reports.
