Corrosion and Protection
Corrosion research at Deakin University targets desalination and water infrastructure, oil and gas refining and production, defence and aerospace, mining and power industries.
The Deakin Corrosion Research Centre is a centre for research in corrosion engineering and surface sciences. The group has a flexible approach towards research and development in a wide range of areas, including infrastructure durability, materials and alloy development, corrosion monitoring and prevention, biocorrosion, and coatings and inhibitors for surfaces and interfaces.
The centre, which draws together researchers from the School of Engineering and the Institute for Frontier Materials, comprises researchers from a range of disciplines, including chemists, physicists, engineers and microbiologists.
Our research in this area focuses on the development of biomaterials and generating new knowledge about the corrosion of materials in a physiological environment. Current projects focus on magnesium and titanium alloys and their use as scaffolds, coronary stents and medical implants.
Our group has a strong focus on the forming of durable superhydrophobic/superoleophobic coatings from water media through assembly of low surface energy substances. Such coatings can be applied to a range of materials to enhance corrosion protection. We have recently developed new coatings with improved strength and durability.
As a major partner in the Energy Pipelines CRC, our research focuses on determining the mechanisms of pipeline failure and methods of prevention. Projects involve developing sensors and detection methods for corrosion in areas that are difficult to access; and investigating the effect of railway currents on cathodic protection methods.
Together, these projects aim to improve energy pipeline industry inspection, repair and maintenance practices and to inform the relevant Australian standards.
Magnesium and aluminium alloys suffer severe corrosion in saline environments. Rare earth inhibitors offer significant corrosion protection and our group is carrying out ongoing research to fully understand how they work.
Ionic liquids are being investigated as corrosion inhibiting films on Mg and Al alloys. Successful surface films have been formed and the influence of chemistry, applied potential, temperature and time are being investigated.
