Materials Engineering discusses a master's thesis on the recycling of local industrial waste to produce corrosion inhibitors for mild steel in different corrosion media
The thesis of the student Sarmad Sharq Nuri aimed to examine two types of local industrial waste, sodium silicate and styrene-butadiene with different concentrations, to be used as corrosion inhibitors for soft steel in a 3.5% NaCl solution.
The corrosion rates obtained from polarization measurements showed good inhibition efficiency, and the optimum concentration of sodium silicate at 3 ml was with an inhibition efficiency of 84.5%, and for styrene-butadiene at 4 ml with an inhibition efficiency of 98.5%. The surface analysis through FTIR, FESEM, and XRD assays showed that these inhibitors contain many functional groups that act as corrosion inhibitors. Also, the absorption and presence of inhibitor particles on the metal surface was confirmed, as they form a soft protective layer that protects the metal.
The discussion committee consisted of
Prof. Dr. Abbas Khammas Hussein, Chairman and membership of each of the Professors. Nahed Mahmoud Ali and Dr. Ahmed Muzaffar Hashem and the supervision of Prof. Dr. Fadel Abbas Hashem and Prof. Dr. Nevin Gamal Abdel Qader.
As well as evaluating the thesis scientifically by Prof. Ali Hobi Halim from Babylon University and Prof. Khaled Hamid Rashid from the University of Technology and Linguistically by Prof. Laith Waddah Ismail from the University of Technology
