Abstract: The Al2O3 coating at the surface of 1Cr18Ni9Ti stainless steel was fabricated by detonation jet spray technique and its hydrogen permeability was measured. The SEM observation showed the coating composite was compact, homogeneous and free from defect, coupled with a better interfacial combination and a stronger resistance to cooling-heating cycles. The deuterium permeability of the coating is lower about three orders of magnitude than that of 1Cr18Ni9Ti stainless steel at 1.03MPa and 400℃ and 600℃.
