Provide an overview of corrosion measurement methods. Demonstrate an understanding of electrochemical measurements techniques, and identify possible sources of error in such measurements. Control potential or current using a potentiostat, and measure potentio-/galvano-static, step, and dynamic polarization curves, and explain their theoretical basis. Define the direct current (DC) and alternating current (AC) techniques: theory, limitations with typical applications. Provide an understanding of coating systems: laser surface treatments, surface morphology, mechanical surface treatments, and electro-plating. Discuss oxidation kinetics and rate laws of metals and alloys. Introduce to failure analysis with corrosion. Discuss the Industrial application and economic benefits of corrosion control. |
