摘　　要：采用英国Micro Materials公司生产的Nano Test 600型纳米多功能测试仪,对电热爆炸喷涂方法制备的FeAl、FeCrAl、FeCrAlRE 3种电爆喷涂层,进行力学性能测试,通过3种涂层加卸载曲线的对比,以及每种涂层的硬度、弹性模量的测取,分析铁基3种电爆喷涂层的力学性能及涂层表面规律,从而优化电爆喷涂工艺参数。The mechanical performance of three electro-thermal explosion spraying layers （FeAl, FeCrAl, FeCrAlRE） were tested and analyzed by adopting british nano multi-functional testing instrument type Nano Test 600. Meanwhile through comparing their loading and unloading curves, measuring the spring modulus and hardness, analyzing the surface rules of those three spraying layers, better technology parameter of electro-thermal explosion layer were found in this paper.
