About this course

Corrosion is a phenomenon of great importance because of its disastrous effects on the economy, safety, energy consumption and environment. The oil and gas industry in Nigeria for instance loses up to $765 Million USD yearly to corrosion, with profound environmental degradation due to products spillage.

This short industry course in Corrosion control provides unique and comprehensive training on the theory and practice of corrosion and corrosion control interventions in varied environments. By means of an innovative blended-learning approach involving classroom teaching and practical hands-on sessions, the students will receive fundamental training on corrosion appreciation and monitoring as well as diagnosing corrosion problems and choosing appropriate corrosion control technologies to solve diverse corrosion-associated problems. This course provides an exceptional opportunity to develop and diversify their skill sets and ultimately enhance their employability of participants across a broad spectrum of national, regional and multinational companies.

Syllabus

The Corrosion Phenomenon: Definition of corrosion. Electrochemistry of corrosion. Corrosion in different environments. Factors that influence rate of corrosion. Uniform and galvanic corrosion, Localized (Pitting and crevice) corrosion, Galvanic corrosion, De‐alloying, Passivation, Electrochemical and semiconducting properties of passive films. Metallurgical Aspects: Introduction to Metallurgy. The microstructure of common metals/alloys. Defects in metals (grain boundaries, inclusions, etc). Effect of microstructure and metallurgical factors on corrosion behavior of materials. Corrosion Monitoring Techniques: Classical methods (gravimetric, gasometric, thermometric); Electrochemical methods (polarization, impedance, noise, voltammetry);Surface imaging techniques (microscopy, scanning probe techniques); Surface analysis (XPS, EDX, FTIR,); Pourbaix Diagram (Potential - pH Diagram), Evans diagram. Basic Corrosion Mechanisms: Corrosion of iron and steel. Corrosion of aluminium alloys. Corrosion of magnesium alloys. Corrosion in different environments: Acidic solution, salt water, alkaline solution, atmosphere, Microbial influenced corrosion, high temperature oxidation.
