Electro-deposition method was used to incorporate rice husk ash (RHA) into the Zn-ZnO- XRHA composite coatingfor mild steel pipeline exterior coating from a chloride-based bath. Zn-ZnO- XRHA composite coatings were obtained for x = 0 g, 10 g and 20 g at a constant bath temperature of 75 °C, constant stirring rate of 400 rpm, 1.4 A current and 15 min deposition span. Scanning electron microscopy (SEM) with energy dispersive spectrometer (EDS), X-ray diffractometry (XRD) and atomic force microscopy (AFM) were used to study the coated surface. Coatings suitability on exposure to adverse environment was assessed in 3.5% NaCl in situ solution using CHI604E electrochemical analyzer. The result showed corrosion protection of the substrate owing to the decline in corrosion rate from 3.2571 mm/yr to 0.1254 mm/yr. The higher positive value of the E_corr of the coatings relative to the substrate inclines the developed coatings to the class of anodic inhibitors.

采用电沉积方法将稻壳灰（RHA）掺入Zn-ZnO-XRHA复合涂层中，用于氯化物基镀液的低碳钢管道外涂层。得到 Zn-ZnO-XRHA 复合涂层，x = 0 g、10 g 和 20 g，恒温槽温度为 75 °C，恒定搅拌速率为 400 rpm，1.4 A 电流和 15 分钟沉积跨度。使用带有能量色散光谱仪 (EDS)、X 射线衍射仪 (XRD) 和原子力显微镜 (AFM) 的扫描电子显微镜 (SEM) 来研究涂层表面。使用 CHI604E 电化学分析仪在 3.5% NaCl 原位溶液中评估涂层对暴露于不利环境的适用性。结果表明，由于腐蚀速率从 3.2571 毫米/年下降到 0.1254 毫米/年，基体得到了腐蚀保护。涂层的E _corr相对于基材的较高正值使开发的涂层倾向于阳极抑制剂类。
