MATERIAL - HARD ANODIC COATINGS ON ALUMINUM - PHYSICAL AND CHEMICAL PROPERTIES - EVALUATION OF
Abstract
Hard anodic coatings of approximately 0.002-in. thickness were applied to bare 7075-T6 and 2024-T3 aluminum alloys by the Hardas, Sanford and Alcoa 226 processes. The Alcoa 226 coating was not successfully applied to 2024-T3 aluminum due to excessive 'burning' of the material during processing. The hard anodic coatings were evaluated by tests to determine their porosity, abrasion resistance, hardness, adhesion and dielectric strength. Tests were also conducted to determine the effect of the coatings on the tensile and fatigue properties of the two aluminum alloys. (Author)
