Abstract:A systematic investigation of candidate hydrogen permeation materials deposited on various substrates using pulsed laser deposition (PLD) has been performed. The investigation focused on application of leading permeation-resistant material types on stainless steel substrates and evaluation of the stability of the deposited coatings. Type 304L stainless steel substrates were coated with aluminum oxide, chromium oxide, and aluminum. Characterization of the coating-substrate system adhesion was performed using scratch adhesion testing. Coating stability and environmental susceptibility were evaluated for two conditions—air at 350°C and Ar-H2 at 350°C for up to 100 h. Results from this study have shown these coatings to be robust and the pulsed laser deposition process to be an extremely versatile technology.
