Abstract

The relationship between the composition, structural-phase state, and tribological characteristics of ion-plasma coatings based on high-entropy alloys of the CrTiZrNbHf and CuCrMnFeCoNi systems obtained by cathodic arc deposition and magnetron sputtering was investigated. The study included scanning electron microscopy, energy-dispersive analysis, X-ray diffraction analysis, nanoindentation, and tribological testing at temperatures of –60 ± 5, +25, and +150 ± 5°C using the ball-on-plate scheme. It was found that the CrTiZrNbHf coating forms a multiphase nanocrystalline partially amorphous structure with a BCC lattice, with a significant deviation from equiatomicity (>30%). The CuCrMnFeCoNi coating forms a single-phase FCC structure of a solid solution with a chemical composition close to equiatomic. The hardness of coatings based on high-entropy alloys of the CrTiZrNbHf and CuCrMnFeCoNi systems is three times higher than the value for a 40NiCrMo6 steel substrate. A comparison of tribological properties revealed that the CuCrMnFeCoNi coating has the lowest coefficient of friction at room temperature, and wear resistance is three to eight times higher than that of CrTiZrNbHf over the entire temperature range.

离子等离子体涂层CrTiZrNbHf和CuCrMnFeCoNi的结构-相特征和摩擦学性能

研究了阴极电弧沉积和磁控溅射制备的CrTiZrNbHf和CuCrMnFeCoNi高熵合金离子等离子体涂层的成分、结构相态和摩擦学特性之间的关系。研究包括扫描电子显微镜、能量色散分析、x射线衍射分析、纳米压痕和在-60±5°C、+25和+150±5°C温度下使用球-板方案的摩擦学测试。结果表明，CrTiZrNbHf涂层形成具有BCC晶格的多相纳米晶部分非晶结构，与等原子性偏差较大（>30%）。CuCrMnFeCoNi涂层形成固溶体的单相FCC结构，化学成分接近等原子。基于CrTiZrNbHf和CuCrMnFeCoNi体系的高熵合金涂层的硬度比40NiCrMo6钢基体的硬度高3倍。摩擦性能比较表明，CuCrMnFeCoNi涂层在室温下具有最低的摩擦系数，在整个温度范围内的耐磨性是CrTiZrNbHf涂层的3 ~ 8倍。
