The microstructures, electrochemical, and hardness properties of deposited Ni-doped ZnO thin films on ultrasonically cleaned 316L stainless steel (316L ST) employing a low-cost chemical spray pyrolysis technique (CSPT) was examined in this work. The films were prepared at various concentrations using commercially available purity zinc acetate and nickel acetate as the precursor sources. The result of x-ray diffractometry (XRD) showed that the films have polycrystalline structure with all the films consisting of single phase ZnO hexagonal wurtzite structure. Scanning electron microscopy (SEM) result affirmed that the coated films adhered to the substrates and equally spread through the substrate surfaces. The surface microstructure of the 316L ST improves with Ni content. The corrosion resistance of the 316L ST was observed to improve with the coated films. Hardness value of the uncoated 316L ST was observed to increase from 139.15 HV to 233.03 HV of coated S3 (9% nickel acetate (0.2 M) and 91% zinc acetate (0.2 M)).

在这项工作中，研究了采用低成本化学喷雾热解技术 (CSPT) 在超声清洗的 316L 不锈钢 (316L ST) 上沉积的 Ni 掺杂 ZnO 薄膜的微观结构、电化学和硬度特性。使用可商购的纯度乙酸锌和乙酸镍作为前体来源以各种浓度制备薄膜。X射线衍射(XRD)结果表明薄膜具有多晶结构，所有薄膜均由单相ZnO六方纤锌矿结构组成。扫描电子显微镜 (SEM) 结果证实涂层膜粘附在基材上并均匀地扩散到基材表面。316L ST 的表面微观结构随着 Ni 含量的增加而改善。观察到 316L ST 的耐腐蚀性能随着涂层薄膜的增加而提高。观察到未涂层 316L ST 的硬度值从 139.15 HV 增加到涂层 S3（9% 醋酸镍 (0.2 M) 和 91% 醋酸锌 (0.2 M)）的 233.03 HV。
