Description
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual destruction of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion.The corrosion allowance is how much material is added to the design thickness to allow for in-service corrosion. The allowance is usually added to the minimum required thickness for each component, or a corrosion-resistant cladding is provided to protect the vessel from the service environment.Corrosion rate is the speed at which any metal in a specific environment deteriorates. It also can be defined as the amount of corrosion loss per year in thickness. The speed or rate of deterioration depends on the environmental conditions and the type and condition of the metal under referenceIn this course we are going to cover the content in the following steps1.What is Corrosion allowance2.What is Corrosion rate3.Relationship b/w Corrosion Rate & Corrosion allowance4.Faraday’s Laws5.Electrochemical Corrosions6.Corrosion Current7.Corrosion Density8.Equivalent weight for Pure Elements & Alloys9.Formula for Corrosion Rate from Faraday’s Laws10.Tafel Plots: To calculate the corrosion current11.Examples of electrochemical parameters for few elements12.Actual Calculations for Pure elements & Alloys•Corrosion current•Corrosion Density•Equivalent weight•Corrosion rate
