Erosion and Its Control

Abstract

Gun erosion is a complicated process which involves a number of interrelated factors. There is general agreement that erosion is a function of bore temperature but this does not eliminate controversy about its causes or the relative importance of different factors. The three effects involved in gun erosion are thermal, chemical, and mechanical. In the case of the most important erosion, that of steel bores at the origin-of-rifling, the chief factor is probably thermal. However, no matter what the specific mechanism of erosion, it is a function of the rate of heat transferred to the bore. It can only be controlled by making the steel bore more resistant to temperature by coating it with a layer of another material or by lowering the rate of heat transfer from the propellant gases.
