In this study, NiCoCrAlYSiHf coatings deposited via arc ion plating technique were modified by high-current pulsed electron beam (HCPEB) irradiation with different pulses. The coarse surface of the original coating was completely modified, and the modification effects of HCPEB irradiation, including surface finishing, composition optimization, and microstructural adjustment were obtained. The transient oxidation behavior of original and irradiated coatings was comparatively investigated under 1100 °C for 10 h. Experiment and characterization results showed that the remelting effects induced by HCPEB irradiation could greatly influence the growth behavior of the thermally grown oxides (TGO), presenting as the rapid formation of a complete and dense α-Al₂O₃ layer in the transient oxidation stage, which guaranteed the protective effect of the AIP-MCrAlYX type coatings in subsequent oxidation stages.

在这项研究中，通过电弧离子镀技术沉积的 NiCoCrAlYSiHf 涂层通过不同脉冲的高电流脉冲电子束 (HCPEB) 辐照进行改性。对原始涂层的粗糙表面进行了彻底的改性，获得了HCPEB辐照的改性效果，包括表面光洁度、成分优化和微观结构调整。对比研究了原始涂层和辐照涂层在 1100°C 下 10 小时的瞬态氧化行为。实验和表征结果表明，HCPEB 辐照引起的重熔效应可以极大地影响热生长氧化物 (TGO) 的生长行为，表现为快速形成完整致密的 α-Al ₂ O ₃层，保证了 AIP -M CrAlY X型涂层在后续氧化阶段的保护作用。
