Aluminum nitride (AlN) coatings have been considered for corrosion-resistant materials applicable to the aluminum (Al) industry where the AlN comes in direct contact with molten Al above 933 K. AlN coatings were synthesized by suspension plasma spray (SPS) technology using Al powder mixed with melamine suspended in hexadecane. The use of fine Al (1-5 µm) particles did not yield more than 10% AlN in the coatings. Mixing the Al powder with promotional additives such as B, BN, Mo, Y₂O₃, AlN, or Al₄C₃ solves the fine particle agglomeration and stimulates the formation of AlN in the coatings which enhances their corrosion resistance. The optimum amount of AlN promoter was 0.22 wt.% of the total suspension mass, producing up to 72% AlN in the coating as determined by Rietveld quantitative analysis (RQA) using x-ray diffraction (XRD). Another way to improve the AlN formation in the coating by post-deposition nitridation and also solve fine Al particle agglomeration is to use a wide particle size distribution of Al, with the optimum ratio being 3:1, that is, (1-5 µm):(17-35 µm). XRD analysis indicated that the coating exhibited up to 80% AlN. The coatings Vickers hardness is related to their AlN content reaching 1644 Hv (80% AlN). The coatings were tested for corrosion resistance by direct contact with molten Al-5 wt.%Mg alloy at 1123 K and found to be stable. Ab initio Born–Oppenheimer molecular dynamics (BOMD) simulation predicted these experimental results. Indeed at 1200 K, molten Al and AlN exhibit weak van der Waals interactions. The AlN_(s)-Al_(l) interfacial energy was calculated to be 18.2 kJ mol⁻¹ for hexagonal AlN phase and 56.4 kJ mol⁻¹ for cubic AlN, which means that it lies within the physisorption regime, and therefore, no reaction occurs between Al_(l) and AlN_(s) which confirms non-wetting application in the Al industry.

氮化铝 (AlN) 涂层被认为是适用于铝 (Al) 行业的耐腐蚀材料，其中 AlN 与 933 K 以上的熔融 Al 直接接触。AlN 涂层是通过使用 Al 的悬浮等离子喷涂 (SPS) 技术合成的粉末与悬浮在十六烷中的三聚氰胺混合。使用细小的 Al (1-5 µm) 颗粒不会在涂层中产生超过 10% 的 AlN。将铝粉与 B、BN、Mo、Y ₂ O ₃、AlN 或 Al ₄ C _{3等促进性添加剂混合}解决了细颗粒的聚集并促进了涂层中 AlN 的形成，从而增强了它们的耐腐蚀性。AlN 促进剂的最佳用量为总悬浮质量的 0.22 wt.%，通过使用 X 射线衍射 (XRD) 的 Rietveld 定量分析 (RQA) 确定涂层中的 AlN 含量高达 72%。另一种通过沉积后氮化改善涂层中AlN形成并解决细Al颗粒团聚的方法是使用Al的宽粒径分布，最佳比例为3：1，即（1-5 µm ):(17-35 µm)。XRD 分析表明涂层显示出高达 80% 的 AlN。涂层维氏硬度与其AlN含量达到1644 Hv（80% AlN）有关。通过直接接触熔融的 Al-5 wt 来测试涂层的耐腐蚀性。%Mg 合金在 1123 K 时发现是稳定的。从头算 Born-Oppenheimer 分子动力学 (BOMD) 模拟预测了这些实验结果。实际上，在 1200 K 时，熔融 Al 和 AlN 表现出弱范德华相互作用。氮化铝_(s) -Al _(l)界面能计算为六方 AlN 相为 18.2 kJ mol -1 ，立方 AlN 为 56.4 kJ mol ^{-1 ，}这意味着它位于物理吸附范围内，因此，两者之间不会发生反应Al _(l)和 AlN _(s)证实了在铝工业中的非润湿应用。
