Effect of Environmental Parameters on Corrosion of Metal Steel in Stagnant Fresh Water Using Finite Element Approach

Abstract

Corrosion as the determination or destruction of metal due to the reaction with it environment has posed a large amount of threat to industrial plants, human, increased cost of maintenance of plant and like cause injury to human due to accident in work place. This work studies the effect of environmental parameters of corrosion of three types of steel, Cast iron, mild steel and stainless steel in stagnant water media using finite element approach.  It uses experiments to study the impacts of some of the environmental factors on the corrosion of several steel materials. However, due to cost and time consumption of this process, numerically analyses have been used to complement the understanding of the corrosion process. This work also review the latest studies on the impact of environmental factors on corrosion of some steel materials used in the industry. Some important experimental procedures and results of works done in relation to environmental factors on steel materials are discussed. The review will allow many manufacturers, designers and operators of industrial steel materials to consider the effect of each environmental factor on the steel material and select a better grade of steel material that can withstand the effect of the prevailing environmental factor in that region. The most important parameters studied in this work include PH, Conductivity and Temperature etc. The work uses 3 different types of water from three different sources to study the effect of environmental parameters on the corrosion of the different types of steel.
