Effect of the Electrolyte Temperature and the Current Density on a Layer Microhardness Generated by the Anodic Aluminium Oxidation

<div>The layer surface structure: (a) c(H2SO4) = 0.87 mol·L−1, c(C2H2O4) = 0.13 mol·L−1, T = 12°C, U = 8.5 V, t = 15 min. (b) c(H2SO4) = 0.87 mol·L−1, c(C2H2O4) = 0.13 mol·L−1, T = 32°C, U = 11.5 V, t = 35 min.</div>
