TY - JOUR ID - 23802 AU - Gombár, M - Kmec, Ján - Badida, M - Sobotová, L - Vagaská, A - Michal, P PY - 2014 TI - The simulation of the temperature effects on the microhardness of anodic alumina oxide layers JF - Metalurgija IS - 53 SP - 59-62 EP - 59-62 PB - Hrvatsko metalurško družstvo (HMD) - Croatia Metallurgical Society (CMS) SN - 05435846 KW - anodizing of aluminium KW - microhardness KW - simulation KW - design of experiments N2 - In order to improve the mechanical properties of the layer deposited by anodic oxidation of aluminum on the material EN AW-1050 H24, in the contribution was investigated the microhardness of the deposited layer as a function of the physic-chemical factors affecting in the process of anodic oxidation at the constant anodic current density J = 3 A.dm-2 in electrolyte formed by sulfuric acid and oxalic acid, with the emphasis on the influence of electrolyte temperature in the range – 1,78 °C to 45,78 °C. The model of the studied dependence was compiled based on mathematical and statistical analysis of matrix from experimental obtained data from composite rotation plan of experiment with five independent variable factors (amount of sulfuric acid in the electrolyte, the amount of oxalic acid in the electrolyte, electrolyte, anodizing time and applied voltage).
