Abstract

It has been reported that the size and shape of the pores depend on the structure of the base metal, the type of electrolyte, and the conditions of the anodizing process. The paper presents thin AlO oxide layer formed under hard anodizing conditions on a plate made of EN AW-5251 aluminum alloy. The oxidation of the ceramic layer was carried out for 40-80 minutes in a three-component SAS electrolyte (aqueous solution of acids: sulphuric 33 ml/l, adipic 67 g/l, and oxalic 30 g/l) at a temperature of 293-313 K, and the current density was 200-400 A/m. Presented images were taken by a scanning microscope. A computer analysis of the binary images of layers showed different shapes of pores. The structure of ceramic AlO layers is one of the main factors determining mechanical properties. The resistance to wear of specimen-oxide coating layer depends on porosity, morphology, and roughness of the ceramic layer surface. A 3D oxide coating model, based on the computer analysis of images from a scanning electron microscope (Philips XL 30 ESEM/EDAX), was proposed.

摘要

据报道，孔隙的尺寸和形状取决于基体金属的结构、电解液的类型以及阳极氧化过程的条件。本文介绍了在EN AW - 5251铝合金制成的板材上，在硬质阳极氧化条件下形成的薄氧化铝层。陶瓷层的氧化在三元SAS电解液（酸的水溶液：硫酸33毫升/升、己二酸67克/升和草酸30克/升）中于293 - 313K的温度下进行40 - 80分钟，电流密度为200 - 400A/m²。所呈现的图像由扫描显微镜拍摄。对层的二元图像进行计算机分析显示出不同形状的孔隙。陶瓷氧化铝层的结构是决定机械性能的主要因素之一。试样 - 氧化物涂层的耐磨性能取决于陶瓷层表面的孔隙率、形态和粗糙度。基于对扫描电子显微镜（飞利浦XL 30 ESEM/EDAX）图像的计算机分析，提出了一种三维氧化物涂层模型。
