一种新型FeB-10重量% Mo-12重量%分别采用放电等离子烧结（SPS）和活性燃烧高速空气喷涂（AC-HVAF）工艺制备了Al0.25FeNiCoCr（简称FeB-10 Mo-12 HEA）金属陶瓷和涂层。对涂层的显微组织、相组成、密度、显微硬度、抗热震性和耐锌液腐蚀性能进行了详细的表征。结果表明，涂层的相组成与金属陶瓷相同，均由（Fe，Al，Ni，Co，Cr）B固溶体、（Fe，Al，Ni，Co，Cr）2 B固溶体和Mo相组成。高熵合金中的Al、Fe、Ni、Co、Cr等元素固溶于FeB和Fe_2B中，降低了它们的脆性。添加Mo（其在450 °C下不与Zn发生共晶反应）和腐蚀产物（δ相）提高了新型金属陶瓷的耐腐蚀性。与SPS制备的金属陶瓷相比，AC-HVAF制备的涂层密度较低，显微硬度较低，耐锌液腐蚀性能较差，这是由于涂层呈层状结构，在热应力作用下易产生裂纹并扩展。
A novel FeB-10 wt.% Mo-12 wt.% Al0.25FeNiCoCr (denoted as FeB-10 Mo-12 HEA) cermet and coating were prepared by spark plasma sintering (SPS) and an activated combustion high-velocity air fuel (AC-HVAF) spraying process, respectively. The microstructure, phase compositions, density, microhardness, thermal shock and corrosion resistance of the cermet and coating to molten zinc were characterized in detail. The results show that the phase composition of the coating was the same as that of the cermet, which was composed of an (Fe, Al, Ni, Co, Cr)B solid solution, an (Fe, Al, Ni, Co, Cr)2B solid solution and a Mo phase. The brittleness of FeB and Fe2B was reduced by the Al, Fe, Ni, Co and Cr elements of the high-entropy alloy that was dissolved into them. The addition of Mo, which did not undergo a eutectic reaction with Zn at 450 °C, and the corrosion products (δphase) increased the corrosion resistance of the novel cermet. Compared with the cermet that was prepared by SPS, the coating that was prepared by AC-HVAF had a lower density, lower microhardness value and worse corrosion resistance to molten zinc because of the layered structure of the coating, in which cracks could form and propagate easily under the action of thermal stress.
