In this subject, students will learn reduction and oxidation reactions (electrochemical process) which forms the fundamental of corrosion. Knowledge on electrochemistry will extend to corrosion cells, corrosion potentials, thermodynamics and kinetics of corrosion. The focus will be on the application of Nernst equation (thermodynamics) to determine the likelihood of corrosion and the application of Butler-Volmer equations (kinetics) to determine corrosion rate. Different corrosion behaviour of various metals including passivity of passive alloys will be discussed. Various forms of corrosion such as localised corrosion, uniform corrosion, stress corrosion cracking, etc., will be investigated. The subject also covers corrosion testing, monitoring techniques, and prevention plans.
Please Note: If it’s your first time studying a Curtin University subject you’ll need to complete their compulsory ‘Academic Integrity Program’. It only takes two hours to complete online, and provides you with vital information about studying with Curtin University. The Academic Integrity Program is compulsory, so if it’s not completed your subject grades will be withheld.
