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 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...
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 کاملAnneal-Hardening Behavior of Cr-Fe-C Alloy Deposits Prepared in a Cr3+-Based Bath with Fe2+ Ions
Cr-Fe-C alloy deposits were successfully prepared on high-carbon tool steel in a Cr3+-based electroplating bath containing Fe2+ ions and suitable complex agents. A Cr-based alloy deposit was obtained with an electroplating current density higher than 25 Adm-2, and a Fe-based alloy deposit was obtained using a current density of 20 Adm-2. Following electroplating, these alloy deposited specimens...
متن کاملZinc Alloy Electrodeposition for Corrosion Protection
t is known that the protective value of zinc is partially a result of its ability to form a protective film when plated on a base metal, such as steel. The zinc is sacrificial and corrodes I preferentially to protectthe steel. Although pure zinc coating provides some degree of protection for the substrate, in a severe corrosion environment, zinc is consumed rapidly. For this reason, it is usual...
