Application of the Image Analysis Methods for the Study of AlO Surafce Coatings

Anodic oxidation of aluminum alloy in a ternary solution of SFS (sulfuric, phthalic and oxalic acids) with 30g of tungsten disulfide (WS₂) powder was carried out in order to obtain the aluminum oxide layer named in article as Al₂O₃/WS₂ coatings. The microstructures of surface of obtained coatings were investigated. The subject of the analysis was a threadlike hill structure visible on the surface of coatings as bright ridges. The computer image analysis was performed in order to study the influence of electrolysis time and temperature of acids bath on the volume fraction V_V of the area of the surface with filamentous hill’s structure.
