Investigation of Tribological Behavior of Electrodeposited Cr, Co-Cr and Co-Cr/TiO2 Nano-Composite Coatings
Electrodeposition is a simple and economic technique for precision coating of different shaped substrates with pure metal, alloy or composite films. Dc electrodeposition was used to produce Cr, Co-Cr and Co-Cr/TiO2 nano-composite coatings from Cr(III) based electrolytes onto 316L SS substrates. The effects of TiO2 nanoparticles concentration on co-deposition of these particles along with Cr con...
متن کاملBiotransformation of chromium (Cr-VI to Cr III) from tannery effluent using bacteria and fungi
Chromium, a priority pollutant is well known for its mutagenicity, carcinogenicity and teratogenicity in humans, animals and plants. Extensive use of chromium in industries such as leather tanning, stainless-steel production, electroplating and wood preservatives have resulted in extensive chromium contaminated soil and ground water. Microorganisms are involved in the removal of toxic wastes, b...
متن کاملCorrosion behaviour of electrodeposited and sputtered Cr coatings and sputtered Ta coatings with α and β phases
The corrosion behaviour of αand β-Ta coatings was compared to that of Cr coatings produced by cylindrical magnetron sputtering as well as electrodeposition. For Ta coatings, the corrosion process was dominated by dissolution of the steel substrate through open pores, however, at the end of 5 days, coating degradation was not observed. In contrast, while open pores were not observed with the Cr ...
متن کاملA method of oxidizing Cr+3 for the determination of trivalent chromium.
The chromium of most chromium compounds exists in the form of triand hexa-valences. Application of a chemical method of determination of the former is difficult because the former is far more inactive than the latter. For example, neither an extraction method by organic solvents or a colorimetric method with diphenylcarbazide is suitable to determine Cr+3, because Cr+3 does not react with diphe...
متن کاملHydrogen Dissolution and Structural Changes in Electrodeposited Cr Films*
Effects of hydrogen on the structure of electrodeposited Cr films have been investigated by combining X-ray diffraction and thermal desorption spectroscopy, systematically varying the plating conditions. A large amount of hydrogen was dissolved at high current densities in a Cr-rich bath at low temperatures, and caused structural changes from bcc to hcp and fcc hydrides with increasing hydrogen...
