چکیده
The present study employed a tungsten pH microelectrode to the formation of trivalent chromium conversion (TCC) coatings on Al, AA 2024-T3 aluminum alloy and AZ91D magnesium in SurTec ChromitAL solutions. had sensitivity –60 mV/pH peak final values for pre-treated 2024 were 4.9 3.5, 4.3 4.1, 4.7 respectively. initial value is great importance influencing coating deposition-driven force thickness. In addition, time attain was 10, 100 20 s alloy, interfacial evolution associated with hydrolysis process weak acid nature zirconium salts as main components TCC Raman spectra revealed presence oxides sulphate solution deposits from in-house Cr/Zr

Trivalent Chromium Conversion Coating for Corrosion Protection of Aluminum Surface
Corrosion is the degradation or deterioration of metal components due to a reaction with the environment. Chromate conversion coating is applied to passivate metallic surface to slow down (and prevent to some extent) corrosion process. Chromate conversion process uses chromium compounds including hexavalent chromium, which is toxic, carcinogenic and hazardous to human health and environment. He...
متن کاملPerformance Properties of Trivalent Chromium
A trivalent chromium electroplating process has been io use commercially in North America since its introduction in 1975. Based upon years of laboratory and in-plant experience and testing, many process performance characteristics and physical properties of deposits have been determined. This paper compares the performance of trivalent chromium with hexavalent chromium processes. Factors such a...

Trivalent chromium, recently identified as the active ingredient of the glucose tolerance factor, appears to be a dietary agent required for maintenance of normal glucose tolerance in the rat. The element, applied in the form of certain coordination complexes, prevents impairment of removal rates of intravenously injected glucose in rats on rations deficient in glucose tolerance factor, and it ...
متن کاملRemoval of Trivalent and Hexavalent Chromium by Seaweed Biosorbent
Protonated or Ca-form Sargassum seaweed biomass bound up to 40 mg/g of Cr(III) by ion exchange at pH 4. An ion-exchange model assuming that the only species taken up by the biomass was Cr(OH)2+ successfully fitted the experimental biosorption data for Cr(III). The maximum uptake of Cr(VI) by protonated Sargassum biomass at pH 2 was explained by simultaneous anion exchange and Cr(VI) to Cr(III) ...
