The dissertation was scientifically evaluated by Assist. Prof. Dr. Kholoud Abdel Saleh/ University of Baghdad / College of Sciences, and linguistically by Lec. Dr. Zainab Naif Rashid/ University of Technology / Department of Applied Sciences

Abstract

The study aimed to improve nickel coating to protect carbon steel from corrosion. Three different percentages of niobium pentoxide were added to nickel coating (10%, 30%, 50%) and by using the plasma DC sputtering technique, the researcher reached an improvement in the corrosion resistance of carbon steel in corrosive medium from 3.5% NaCl

Abstract:

The aim of the study is to improve the performance of heat exchangers by using engineering materials for the purpose of coating a brass tube type (B-111) used in steam condensers for Italian units in the thermal cycle power plant and protecting them from corrosion, unwanted deposits (fouling) and corrosion by erosion. The materials used in coating the samples are epoxy, epoxy with different weight ratios of titanium dioxide nanoparticles TiO₂ (1, 3, 5, 7%) and epoxy with the addition of 1% wt of the MWCNTS. The heat transfer experiments were conducted using a homemade double tube heat exchanger system, where the experiments were conducted on five tubes, which are an uncoated tube, fouled tube and in addition to the three coated tubes and comparison between them. Through this study, the highest corrosion resistance was when adding 7% of titanium dioxide nanoparticles, the contact angle of the coated samples, was the highest angle obtained from epoxy coating with the addition of 1% of the multi-walled carbon nanotubes. As for the study of the effect of coating on the heat performance of the exchanger, experiments showed that the tube coated by epoxy with the addition of 1% of the multi-walled carbon nanotubes had the least effect on the performance compared to the new uncoated tube.
