文章亮点

(1) 制备出了满足耐蚀性和导电性的V/Ce膜层

(2) 研究了V/Ce膜层的形成机理。

(3) 提出膜层成分对导电性的影响，并分析了导电机制

中文摘要

以偏钒酸钠和硝酸铈为主盐，在AZ31B镁合金表面制备了V/Ce转化膜层。利用SEM、激光扫描共聚焦显微镜、XPS等技术对制备的膜层进行微观形貌观察与成分分析，进而探讨了成膜机理。结果表明：化学转化膜表面有着均匀网状微裂纹，并且在其上分布有球状颗粒。膜层物质主要由V、Ce和Mg的氧化物以及CeVO₄组成。采用极化曲线和电化学交流阻抗谱(EIS)评估了基体和转化膜层的耐蚀性。与AZ31B镁合金相比，转化膜层的自腐蚀电位提高了200 mV，腐蚀电流密度降低了两个数量级。EIS测试表明经过化学转化后，镁合金的阻抗值由裸体的2.2 × 10² Ω·cm²增加到1.6 × 10³ Ω·cm²。此外，通过电导率仪和莫特肖特基（MS）曲线研究了涂层的导电性，结果表明膜层导电率为9.657 MS/m，具有N型半导体特性。其导电性和膜层成分的半导体特性有很大关系。

Abstract

Abstract

A V/Ce conversion coating was deposited in the surface of AZ31B magnesium alloy in a solution containing vanadate and cerium nitrate. The coating composition and morphology were examined. The conversion coating appears to consist of a thin and cracked coating with a scattering of spherical particles. The corrosion behavior of the substrate and conversion coating was studied by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Compared with AZ31B magnesium alloy, the corrosion current density of the conversion coating is decreased by two orders of magnitude. The total impedance of the V/Ce conversion coating rise to 1.6 × 10³ Ω·cm² in contrast with 2.2 × 10² Ω·cm² of the bare AZ31B. In addition, the electrical conductivity of the coating was assessed by conductivity meter and Mott-Schottky measurement. The results reveal a high dependence of the conductivity of the coating on the semiconductor properties of the phase compositions.
