Abstract

Magnesium alloy, which draws attention with its lightness and high specific strength, is frequently preferred due to its advantages. However, it is necessary to improve the wear and corrosion properties in order to develop the areas of use in the automotive, aircraft, and space industries. For this purpose, after the surface preparation of the main material WE43 Mg alloy, ZnO and ZrO2 coatings were made and characterized in this study. The surface morphology and structural and chemical properties of the samples were investigated using profilometry, contact angle tests, scanning electron microscopy, and x-ray diffraction. Corrosion tests have been carried out. In order to determine the wear performance of the samples, the wear-related volume losses were measured and the friction coefficients were compared. Layers with 2–6 μm coating thickness were obtained homogeneously on the polished and sandblasted sample surfaces. It was determined that the coating layers grew in the form of columns and did not contain capillary cracks. As a result of the study, it was observed that the ZnO-coated samples had the highest wear and corrosion resistance, and the wear and corrosion resistance of the coatings and magnesium alloy substrates improved.

氧化锌和氧化锆包覆WE43镁合金的耐磨损和耐腐蚀性能

镁合金以其重量轻、比强度高的特点受到人们的关注，因其优点而成为人们的首选。然而，为了在汽车、飞机和航天工业中发展其应用领域，有必要改善其磨损和腐蚀性能。为此，本研究在对主要材料WE43镁合金进行表面制备后，制备了ZnO和ZrO2涂层并对其进行了表征。利用轮廓术、接触角测试、扫描电子显微镜和x射线衍射对样品的表面形貌、结构和化学性质进行了研究。进行了腐蚀试验。为了确定样品的磨损性能，测量了与磨损相关的体积损失，并比较了摩擦系数。在抛光和喷砂样品表面均可获得2 ~ 6 μm厚度的涂层。结果表明，涂层呈柱状生长，不含毛细裂纹。结果表明，zno涂层样品具有最高的耐磨损和耐腐蚀性能，涂层和镁合金基体的耐磨损和耐腐蚀性能均有提高。
