The electrolyte temperature varied from -1.78°C to 45.78°C. The results have showed that while increasing the electrolyte temperature at the current density of 1Axdm-2, the increase in the layer microhardness values is approximately by 66%. While simultaneously increasing themolar concentration ofH2SO4 in the electrolyte, the growth rate of the microhardness value decreases. At the current density of 3Axdm-2, by increasing the electrolyte temperature, a reduction in the microhardness of the generated layer occurs with the anodic oxidation time less than 25 min. The electrolyte temperature is not significant with the changing values of the layer microhardness at voltages less than 10.5V. ER -
