Amorphous coatings (ACs) with the composition of Fe_49.7Cr₁₈Mn_1.9Mo_7.4W_1.6B_15.2C_3.8Si_2.4 were deposited by the arc-spraying technique. The wettability and corrosion performance of Fe-based ACs in 3.5% NaCl solution were investigated using contact angle measurements and electrochemical tests, respectively. Results showed that by controlling the spraying potential, the phase constituent, microstructure, hardness, wettability, and corrosion performance of the coatings were manipulated. With a spraying potential of 26 V, the highly glassy AC exhibited a denser microstructure, higher microhardness, lower surface free energy, and better corrosion resistance than the others. The superior corrosion resistance of the coatings was closely related to the surface hydrophobicity, which was dominantly governed by the microstructure of the coatings. This finding demonstrates the importance of a homogeneous and compact structure for anti-corrosion and provides a quick prediction of corrosion performance among ACs.

通过电弧喷涂技术沉积组成为 Fe _49.7 Cr ₁₈ Mn _1.9 Mo _7.4 W _1.6 B _15.2 C _3.8 Si _{2.4的非晶涂层（ACs）。}分别使用接触角测量和电化学测试研究了铁基活性炭在 3.5% NaCl 溶液中的润湿性和腐蚀性能。结果表明，通过控制喷涂电位，可以控制涂层的相组成、微观结构、硬度、润湿性和腐蚀性能。在 26 V 的喷涂电位下，高度玻璃化的 AC 表现出更致密的微观结构，更高的显微硬度, 较低的表面自由能, 和更好的耐腐蚀性比其他。涂层优异的耐腐蚀性能与表面疏水性密切相关，而表面疏水性主要受涂层微观结构的支配。这一发现证明了均匀和紧凑的结构对于防腐的重要性，并提供了对 AC 腐蚀性能的快速预测。
