Electrocolour and Other Colours, Titration, Curves and Electrolytic Colouring Bath for Anodized Aluminium
نویسنده
چکیده
The properties produced by integral coloured anodic oxide films and sulphuric acid, oxalic acid, maleic acid and different anodizing aluminium alloys -Si, Mg, Fe, Cuare studied. A two stage anodizing procedure was employed. The influence of alloy and solution composition, temperature, concentration, voltage, ampere, time from optimization simplex and anodizing conditions are considered. An oxide disordered structure is formed in the initial stage while an oriented structure is obtained in the second stage. The changes in colour parameters obtained with complex forming electrolytes are explained. Anodizing solutions: sulphosilicylic acid, sulphuric acid. phosphoric acid.

Mechanical Application of Lubricated Nano Porous Anodized Aluminium
Today a major environmental problem is global warming that is mainly caused due to exhaust and emission of gases. The only way to reduce their ill-effect is by improvement in fuel efficiency of I.C. engines, where most of the power is lost to overcome the friction. In this work, nanoporous anodized layer is formed on an aluminium substrate surface by anodization. Anodization was carried out at ...

متن کاملDifferential electrolytic potentiometric determination of some amino acids in dosage forms.
The application of direct-current differential electrolytic potentiometry to the nonaqueous titration of amino acids was investigated. The basic character of amino acids in acetic acid was enhanced to permit their direct titration with perchloric acid. A pair of antimony electrodes was used as an indicating system. The shapes of the titration curves obtained were almost symmetrical with sharp p...
متن کاملAntibacterial activity of porous anodized copper
This study was carried out to synthesize 1D inorganic nanostructure using an electrochemical method without any template and additives. Copper foils were anodized in a KOH bath and were tested for their antibacterial performance. After anodizing, the obtained samples were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) to determine the corresponding morphology an...
