Cr coatings with CrN/Cr multilayers with a layer thickness of 100, 250 and 750 nm were deposited by a multi-cathode magnetron sputtering on E110 zirconium alloy in Ar and Ar + N₂ atmosphere. The mechanical properties of the as-deposited coatings were measured by scratch testing and tribometry. A comparative study of crack and oxidation resistance of the Cr-coated E110 alloy was performed under thermal cycling (1000 °С) and high-temperature (1200–1400 °С) steam oxidation conditions. The influence of the CrN/Cr multilayers and their thickness on the mechanical properties and oxidation resistance of the coated E110 alloy is discussed. It is found that the CrN/Cr multilayers can limit interdiffusion between the coating and E110 alloy at high temperatures only for a short period.

_{在 Ar 和 Ar + N 2}气氛中，通过多阴极磁控管溅射在 E110 锆合金上沉积具有层厚为 100、250 和 750 nm 的 CrN/Cr 多层的 Cr 涂层。通过划痕测试和摩擦测量法测量沉积涂层的机械性能。在热循环（1000°С）和高温（1200-1400°С）蒸汽氧化条件下，对镀铬的 E110 合金的抗裂纹和抗氧化性进行了比较研究。讨论了CrN/Cr多层及其厚度对涂层E110合金的机械性能和抗氧化性的影响。研究发现，CrN/Cr 多层膜在高温下只能在短时间内限制涂层和 E110 合金之间的相互扩散。
