Abstract

ABSTRACT Magnesium alloys are widely used due to their excellent properties, but their corrosion resistance is limited by their high chemical activity. This paper proposes a one-step hydrothermal method with a relatively short reaction time and simple experimental steps for synthesising magnesium alloy coatings with good corrosion protection properties. The surface morphology, chemical composition and corrosion resistance of the in situ generated coatings were investigated using measurements such as field emission scanning electron microscopy (SEM), adhesion cross-cut tape (ACCT) test, X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), electrochemistry and immersion test, the results revealed that the corrosion current density (Icorr) of the coatings decreased by approximately four orders of magnitude and had good corrosion resistance.

一步水热法制备AZ91D镁合金防腐涂层

镁合金因其优异的性能而被广泛应用，但其高化学活性限制了其耐腐蚀性。本文提出了一种反应时间相对较短、实验步骤简单的一步水热法合成具有良好防腐性能的镁合金涂层。使用场发射扫描电子显微镜（SEM）、粘附横切带（ACCT）测试、X射线衍射（XRD）、X射线光电子能谱（XPS）、电化学和浸渍测试等测量手段，研究了原位生成涂层的表面形态、化学成分和耐腐蚀性，结果表明，涂层的腐蚀电流密度（Icorr）降低了大约四个数量级，并且具有良好的耐腐蚀性。
