Abstract

A three-cathode arc-based evaporation system has been used to obtain vacuum ion-plasma high-entropy CrTiZrNbHf coatings. The statistically averaged concentration of components in the coating corresponds to Cr_0.30Ti_0.35Zr_0.25Nb_0.08Hf_0.01. The kinetics of the coating deposition and the process of its structure self-organization have been studied by constructing a diagram of the Movchan–Demchishin–Thornton structure zone. Technological parameters such as the substrate temperature, vacuum chamber pressure, coating deposition rate, ion current density, bias voltage, etc., were combined into the form calculated. It is shown that, for the CrTiZrNbHf system under study, the critical value of the E_bi parameter amounts to about100 MJ/cm³. Exceeding this threshold leads to degeneration of the coating structure in the form of a nuclei-like or droplet-like morphology.

利用多阴极电弧喷涂技术获得的 CrTiZrNbHf (HEA) 离子等离子涂层结构中的自组织过程

利用三阴极电弧蒸发系统获得了真空离子等离子高熵铬钛锌铌铪涂层。涂层中成分的统计平均浓度相当于 Cr0.30Ti0.35Zr0.25Nb0.08Hf0.01。通过构建 Movchan-Demchishin-Thornton 结构区图，研究了涂层沉积动力学及其结构自组织过程。基片温度、真空室压力、镀层沉积速率、离子电流密度、偏置电压等技术参数被合并到计算公式中。结果表明，对于所研究的 CrTiZrNbHf 系统，Ebi 参数的临界值约为 100 MJ/cm3。超过这个临界值会导致涂层结构退化，形成核状或液滴状形态。
