【摘要】 以爆炸喷涂工艺在不锈钢材料上喷涂制备Al2O3涂层,测定了涂层的防氘渗透性。通过SEM观察涂层表面致密、无缺陷,与基体结合强度高,抗冷热循环能力强;在1.03MPa的氘气压力差下,400和600℃时氘在涂层中的渗透率分别比同一条件下氘在1Cr18Ni9Ti不锈钢中的渗透率低约3个数量级。
【Abstract】 The A12O3 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℃.
