Study of Copper Bearing Alloys Corrosion Characteristics
This paper addresses investigation of the corrosion behavior of copper bearing anodes with high nickel content. Anodes are produced from different solid wastes formed during the copper or nickel row materials treatment. Nickel content in anode samples had values up to 10 mas %. The content of tin, lead and antimony was up to 1 % for each of elements. Sulphuric acid solution, concentration of 17...
متن کاملPolystyrene films as barrier layers for corrosion protection of copper and copper alloys.
Dip-coated polystyrene layers of sub-micrometre thickness (85-500nm) have been applied on copper and copper alloys (aluminium brass, copper-nickel 70/30), as well as on stainless steel 304, and produced an effective barrier against corrosion and adhesion of corrosion-relevant microorganisms. According to the dynamic wettability measurements, the coatings exhibited high advancing (103°), recedin...
متن کاملNEW REFRACTORY MATERIALS FOR THE COPPER INDUSTRY
Wear of various basic refractory materials to substitute to currently used magnesia chrome bricks has been studied, measuring matte and slag penetration and dissolution, through different cup and rotary slag tests. High magnesia with and without impregnation, magnesia graphite, magnesia-alumina spinel with and without impregnation, olivine-magnesia and olivine magnesia- graphite bricks, as well...
متن کاملNew inhibitors for copper corrosion *
The study of the effectiveness of several potential copper corrosion inhibitors in acidic media was studied. The investigated thiazole derivative functional groups contain heterocyclic atoms such as nitrogen, sulfur, and oxygen. Thiazole derivatives, 5-benzylidene-2,4-dioxotetrahydro-1,3-thiazole (BDT) 5-(4′-isopropylbenzylidene)-2,4-dioxotetrahydro-1,3-thiazole (IPBDT), 5-(3′-thenylidene)-2,4-...
متن کاملDealloying and Stress Corrosion Craking of Copper Alloys in Cu(I) Solutions
Natural cases of dealloying or stress-corrosion cracking in copper alloys normally occur in oxygenated solutions, where the cathodic reactant is O2 or Cu2+. Within cavities or under deposits, the local environment is enriched in cuprous ions (e.g. CuCl2-, Cu (NH3)2+) and the potential is close to the Cu/Cu+ equilibrium. Such conditions can be simulated macroscopically by stirring powdered Cu2O ...
