The Application of Predictive Model to Describe and Control Technological Process

This paper shows an important influence of amount of sulphuric acid in electrolyte on thickness of aluminium oxide layer created with varying electrolyte temperature. Impact of these variables is shown by using DoE for six factors (amount of sulphuric acid, amount of oxalic acid, amount of aluminium cations, electrolyte temperature, anodizing time, applied voltage). Oxide layer was created with current densities of 1 A.dm-2.
