Hydrogen Embrittlement of Pipelines and Possible CP Effects

Presenter Mike Yongjun Tan is a Professor in Applied Electrochemistry and Corrosion Technologies at Deakin University in Australia. He is also a Research Program Leader of the Energy Pipelines Cooperative Research Centre. Dr Tan’s principal teaching and research interests are in corrosion science and engineering and their applications for enhancing the reliability and durability of civil and industrial infrastructures. He contributed to electrochemical methods for corrosion testing, monitoring and prediction and corrosion inhibitor and anti-corrosion coating research. He is author of some 150 publications and a book entitled “Heterogeneous Electrode Processes and Localised Corrosion”(2012 John Wiley & Sons).

New Volunteering Opportunities

Our Association owes a great deal of its success to the great work done by over 100 volunteers at any given time. Joining one of our committees is a fantastic way to make deep ties and enact positive change across our Association. We're currently seeking to expand the membership on a range of committees including ACA Board Subcommittees, The ACA Foundation and the Young Corrosion Group Steering Committee. So if you're interested in any of these opportunities, we'd love to hear from you.

Examination of a Single Column Pantograph Disconnection Failure

In this presentation, Roger Costanzi discusses a tubular aluminium single column pantograph disconnecting arm from an 82kV disconnector, that was received for examination following failure adjacent to the weld joining the tubular arm to a clevis. Failure of the disconnector arm was a result of exfoliation corrosion arising from the formation of precipitates in the weld heat affected zone (HAZ) joining the extruded tubes to a cast aluminium alloy clevis.

Stress Corrosion Cracking of Cable Bolts

In this presentation, Judy Turnbull addresses the results of the examination of stress corrosion cracking (SCC) of both smooth surface and ribbed wires used in cable bolts. Judy Turnbull is a consultant Metallurgist with Bureau Veritas, undertaking component failure investigations. She has held this role since 2013. Judy has more than 30 years of experience in the engineering field, having worked in heavy engineering, hard rock mining, concrete, oil & gas and pipeline inspection as well as information technology.

Initial Corrosion Behaviour of Spheroidal Graphite Cast Iron and Rust Evaluation in Atmospheric Environment

For the initial corrosion behaviour of spheroidal graphite cast iron in atmospheric corrosion environment, it is quite different from that of carbon steel and weathering steel. This study focused on the initial corrosion behaviours affected by the graphite and Cu in the spheroidal graphite cast iron, the atmospheric exposure test and wet-dry cyclic test were conducted. This presentation from Ichiro Dote, was given at the 2021 Corrosion and Prevention Conference. Ichiro Dote has studied in the Department of Civil Engineering, at Kyushu University as a working doctor from 2018. Where his major field of study is atmospheric corrosion of cast iron. Right now, he is living in Fukuoka, Japan.
