NDT Measurements of Chromium Plate Thickness on Small Caliber Gun Barrel Bores.

Abstract

Chromium-plate thicknesses of gun barrel bores are necessarily assumed since the air gauges used simply provide differences in bore-size reading before and after plating. The only means available to accurately determine plating thickness, including concentricity, is to use destructive methods to examine microspecimens representing cross sections of the gun barrel. The objective of this project was to make use of improved nondestructive testing methods to measure chromium plate thicknesses in small caliber gun barrels.
