Abstract

Pure Zn (Zinc) and its Zn-WO (Zinc-Tungsten trioxide) composite coatings were deposited on mild steel specimens by applying the electrodeposition technique. Zn-WO composites were prepared for the concentration of 0.5 and 1.0 g/L of particles. The influence of WO particles on Zn deposition, the surface morphology of composite, and texture co-efficient were analyzed using a variety of techniques, such as X-ray diffraction (XRD) and scanning electron microscopy (SEM) with Energy Dispersive X-ray analysis (EDX). Higher corrosion resistance and microhardness were observed on the Zn-WO composite (concentration of 1.0 g/L). The higher corrosion resistance and microhardness of 1.0 g/L Zn-WO nanocomposite coatings effectively protect the steel used for the manufacture of products, parts, or systems from chemical or electrochemical deterioration in industrial and marine ambient environments.

摘要

通过采用电沉积技术，将纯锌（Zn）及其锌 - 三氧化钨（Zn - WO）复合涂层沉积在低碳钢试样上。制备了颗粒浓度为0.5 g/L和1.0 g/L的Zn - WO复合材料。使用多种技术，如X射线衍射（XRD）和带有能量色散X射线分析（EDX）的扫描电子显微镜（SEM），分析了WO颗粒对锌沉积、复合材料表面形态和织构系数的影响。在Zn - WO复合材料（浓度为1.0 g/L）上观察到更高的耐腐蚀性和显微硬度。1.0 g/L Zn - WO纳米复合涂层的更高耐腐蚀性和显微硬度有效地保护了用于制造产品、零件或系统的钢材，使其在工业和海洋环境中免受化学或电化学劣化。
