采用卤化物活化包埋渗（HAPC）和微弧氧化（MAO）技术在Nb合金表面制备了NbSi 2/SiO2-Nb 2 O 5多层涂层，涂层由NbSi 2内层和SiO2-Nb 2 O 5外层组成。对比研究了单一NbSi 2涂层和NbSi 2/SiO2-Nb 2 O 5涂层Nb合金在Na 2SO 4/NaCl（3：1 wt.%）混合溶液中的热腐蚀行为。盐在900 °C。NbSi 2涂层和NbSi 2/SiO2-Nb 2 O 5涂层试样的腐蚀速率常数分别为2.16 × 10 - 3 mm s-2和1.04 × 10 - 3 mm s-2。在腐蚀过程中，SiO2-Nb 2 O 5外层起到阻挡作用，促进了连续SiO2膜的形成，并将NbSi 2层与腐蚀盐隔离开来。NbSi 2/SiO2-Nb 2 O 5涂层试样的腐蚀速率较低是由于形成了保护性的SiO2腐蚀膜。
A NbSi2/SiO2-Nb2O5multilayer coating, consisting of a NbSi2inner layer and a SiO2-Nb2O5outer layer, was prepared on Nb alloy through halide activated pack cementation (HAPC) and microarc oxidation (MAO). The hot corrosion behaviors of the single NbSi2coated and the NbSi2/SiO2-Nb2O5coated Nb alloys were comparatively investigated with a mixture of Na2SO4/NaCl (3:1 wt.%) salt at 900 °C. The growth kinetics of the corroded scales follow the parabolic laws, and the parabolic rate constants of the NbSi2coated and the NbSi2/SiO2-Nb2O5coated specimens were 2.16 × 10−3mm s−2and 1.04 × 10−3mm s−2, respectively. During the corroding process, the SiO2-Nb2O5outer layer that serves as a barrier promotes the formation of continuous SiO2scale, and isolates the NbSi2layer from the corrosion salt. The lower corrosion rate of the NbSi2/SiO2-Nb2O5coated specimens is attributed to the formation of the protective SiO2corroded scale.
