The capability devises technology to minimize the effect of corrosion of metal structures. These technologies may be coating systems , sensing systems or predictive methodologies to define the life and optimum maintenance scheduling for structures.
Unfortunately corrosion may prematurely reduce the life of infrastructure, transport vehichles and engineered objects with loss of function , value and safety. This capability meets the challenge of providing technologies (coatings, passivation systems etc) that keep our man-made objects in optimum condition for there lifetime. These technologies must be fabricated from environmentally friendly materials. It also provides tools that allow the right material selection for the required service conditions and sensors and computer models that can predict the future life of structures.
CSIRO provides systems that ensure the lifetime of our engineered world by developing a range of technologies that enhance the intrinsic resistance of materials to degradation, allow optinium material selection and design and monitor the condition of materials and engineered structure to ensure safety and reliability and plan maintenance.
Corrosion Resistant Materials – CSIRO develops green passivation systems and primers containing green inhibitors to protect the common industrial metals (aluminium, steel and zinc). These coatings and passivation processes are based on a knowledge of surface and inhibitor science and are developed in conjunction with high throughput testing technologies
Optimum Materials Selection. Based on CSIRO’s profound knowledge of degradation processes and how they interact with the environment, CSIRO develops computer-based tools to select the best metal or coating system for infrastructure and transport vehicles. For example, we have developed an interactive corrosion map of Australia which allows the selection of the appropriate level of galvanising for any steel product on a domestic building anywhere in Australia.
Condition Monitoring and Prognostics. CSIRO develops sensor suites that can both define the condition of engineered object and predict the rate of degradation. This enables the ability to ensure the safety of the object and also to plan its maintenance.
Corrosion is a billion dollar issue and being able to specify the correct types of materials to use can save money and effort in the future but also cost in the initial construction.
Cerate conversion coatings
Chromates are widely used for inhibiting corrosion, particularly in light metals, and in particular aluminium. Chromates form a fundamental component of so-called conversion coatings which both bind paint to the metal surface and help to inhibit corrosion if the paint is damaged.
