Corrosion Inhibitation Action of p-Substituted Anilines for Corrosion of Copper

New 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-...

Copper Corrosion Inhibitors. A review

The literature dealing with the electrochemical corrosion of copper and possibility of its prevention using inhibitors is examined. Inorganic compounds are investigated as well, but organic compounds and their derivatives in much greater numbers. Researches are directed to influence of compounds structure, concentration, method of application as well as media that inhibitor is used in on inhibi...

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...

Corrosion Behavior of Copper in Chloride Media

The electrochemical behavior of copper in 0.05 M HCl and 0.05 M NaCl carried out at open-circuit potential and at constant anodic potential after one hour has been investigated using electrochemical impedance spectroscopy (EIS) at 20 °C, 40 °C and 60 °C. The formation of copper chloride (CuCl) film does not protect copper from dissolution in the chloride media. The physical properties of the pa...
