Erosive Effects of Various Pure and Combustion-Generated Gases on Metals, Part 1

Abstract

This study presents an experimental investigation of the thermal and chemical erosion characteristics of steel alloys under the short exposure of high pressure and high temperature propellant gases (vented-combustor apparatus) and pure gases (ballistic compressor apparatus). In the vented-combustor tests, the erosion experienced by the alloys is shown to increase with decreasing thermal conductivity and specific heat. The established linear dependence of mass eroded on number of firings suggests that any physical alterations undergone by the eroded surface do not influence future erosion tests. Most significantly, erosion results of the steel alloys (of widely differing compositions) in the ballistic compressor show no distinct difference.
