This paper investigates the effect of crystallographic texture on the corrosion product morphology and corrosion behavior of AZ31 magnesium alloy after immersion in simulated body fluid for 3 days. The microstructure and macrotexture analyses are performed through optical microscopy and x-ray diffraction methods, respectively. The polarization test evaluated the corrosion, and the FESEM electron microscope equipped with EDS was used to investigate the morphology of the corrosion products. According to the results, the morphology of calcium phosphate deposit as a corrosion product at the surface with basal texture was a porous cauliflower shape. In contrast, the calcium phosphate deposit at the surface of the nonbasal texture was uniform and nanoworm-like. The corrosion rate at the basal texture surface was higher than the nonbasal one, which is attributed to the difference in the morphology of calcium phosphate film.

本文研究了浸入模拟体液中3天后，晶体织构对AZ31镁合金腐蚀产物形态和腐蚀行为的影响。微观结构和宏观纹理分析分别通过光学显微镜和X射线衍射法进行。极化测试评估腐蚀，并使用配备EDS的FESEM电子显微镜研究腐蚀产物的形貌。根据结果​​，作为具有基础纹理的表面上的腐蚀产物的磷酸钙沉积物的形态为多孔花椰菜形状。相反，在非基础纹理的表面上的磷酸钙沉积是均匀的和纳米蠕虫状的。基部组织表面的腐蚀速率高于非基部组织。
