Evidence Against Hydrogen Cracking in Gun Bores: A Reply.
Abstract
The present report is a reply to J. H. Underwood's critique of the ARDEC Technical Report entitled "Gray Layers and the Erosion of Chromium Plated Gun Bore Surfaces" by Cote and Richard. At issue is the evidence from the survey study by Cote and Richard, that hydrogen cracking plays no role in damage initiation and chromium spallation. A brief review of the controversy relating to hydrogen cracking and damage initiation in gun bores is presented here. The question of hydrogen cracking beyond the initiation stage is also addressed. Consideration of some of the implications of the proposed hydrogen cracking model and the general observations of the survey study offer reasons to doubt that damage initiation in gun bores is a result of hydrogen cracking, despite the plausibility of the proposed model.
