| 摘 要： | 利用金属导体FeAl系合金箔,电热爆炸产生的瞬间高能量冲击波效应,制备FeAl、FeCrAl、FeCrAlRE等离子体喷涂层。通过涂层SEM等检测,可以看出涂层致密,同时涂层与基体可以形成冶金结合层,涂层与基体之间存在明显的过渡层。经高温氧化、氯化、硫化耐蚀性测试,得出3种等离子体喷涂层的腐蚀变化规律,从而优选出耐高温腐蚀的FeCrAlRE电热爆炸等离子体涂层。

| Abstract: | Three kinds of plasma spray coatings FeAl, FeCrAl and FeCrAlRE were prepared using instantaneous high-energy shock wave effect during electro-thermal explosion of FeAl conductor alloy foil. It was shown that the spray coatings possess mixed nano- and micro-structures, they can form a metallurgical bonding with substrate and an evident buffer layer between coating and base metal. The corrosion rule of these three plasma spray coatings can be obtained through anti-corrosion testes under the conditions of high temperature oxidation, chloridization, and sulfuration, and then The FeCrAlRE electro-thermal explosion plasma spray coating was selected for anti-corrosion and heat resistance use. |
