WA Branch | Technical Presentation |New Aspects of CO2 Corrosion Mechanism
The Globe, Perth | 5:30 – 8:00pm | Wednesday 6 March
The WA Branch of the ACA is pleased to invite you to hear Professor Brian Kinsella and Ms. Hoda Ehsani from Curtin talk about New Aspects of CO2 Corrosion Mechanism, over a pint.
In CO2 corrosion of carbon steel it is popularly believed that direct reduction of carbonic acid (H2CO3) contributes an important part to the cathodic side of the reaction. More recent work has challenged this belief and proposes that only reduction of protons (H+) needs to be considered. The dissolved CO2 merely acts as a reservoir or buffer for the supply of hydrogen ions. This mechanism has become known as the buffer effect. The impact of the buffer mechanism in predicting or modelling the rate of CO2 corrosion, especially at high CO2 partial pressure, will be presented. The presentation will feature two experiments 1) on CO2 equilibria and 2) to demonstrate the effect of magnetite on CO2 corrosion of bare steel. Some likes and dislikes in providing corrosion data will be given during the informal presentation.
