Interfacial Structures in Thermal Spray Coatings. The use of coatings on the surfaces of components provides high levels of resistance to mechanical damage, corrosion, oxidation or thermal degradation. As a result, coated components exhibit increased lifetimes and reliability. However, the durability of such components is still crucially limited by the quality of the coating. An improved understanding of the bonding mechanisms that occur during the deposition of such coatings, prepared through t ....Interfacial Structures in Thermal Spray Coatings. The use of coatings on the surfaces of components provides high levels of resistance to mechanical damage, corrosion, oxidation or thermal degradation. As a result, coated components exhibit increased lifetimes and reliability. However, the durability of such components is still crucially limited by the quality of the coating. An improved understanding of the bonding mechanisms that occur during the deposition of such coatings, prepared through thermal spray methods, will provide improvements in coating structure and thus, component performance and lifetime. This will benefit a wide range of manufacturing industries that use such coatings. Read moreRead less
Stronger zinc alloys for more flexible biodegradable stents. This project aims to develop stronger zinc alloys for a new class of biodegradable metallic stents. A key challenge for biodegradable stent technology is to make stents as thin as possible while also being strong. This project will develop ultra-high strength zinc alloys that can be used to fabricate thinner biodegradable stents for easier surgical operation. The project outcomes should be a major step in the design and development of ....Stronger zinc alloys for more flexible biodegradable stents.

This project will develop ultra-high strength zinc alloys that can be used to fabricate thinner biodegradable stents for easier surgical operation. The project outcomes should be a major step in the design and development of a new generation of biodegradable stents that will avoid the risks associated with existing products and potentially create a better life for millions of patients worldwide.Read moreRead less
Biodegradable magnesium alloy scaffolds for bone tissue engineering. This project aims to develop a class of porous, biocompatible, biofunctional and biodegradable magnesium alloy scaffolds with designed pore architecture and mechanical properties mimicking those of natural bone for tissue engineering applications. These magnesium alloy scaffolds will be biocompatible, able to bear loads, and will be gradually replaced by natural bone. The outcomes are expected to benefit the ageing population a ....Biodegradable magnesium alloy scaffolds for bone tissue engineering.

These magnesium alloy scaffolds will be biocompatible, able to bear loads, and will be gradually replaced by natural bone. The outcomes are expected to benefit the ageing population and people with bone abnormalities.Read moreRead less
Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U ....Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U.S.A. An understanding of the factors that maximise the containment of cracks is essential to the design and development of the next generation of advanced layer composites for many biomechanical and other engineering applications.Read moreRead less
Titanium Alloy Scaffolds for Osseointegration Implant Materials. Australians' life expectancies are among the highest in the world. Degeneration of load bearing bones in the elderly of age 65 and over often requires the inception of biomaterial implants. For the hip and knee replacements alone, there are over 52,000 operations performed in Australia each year at an estimated cost of over $500 million. The success of these procedures depends on the implant biomaterials. The outcomes of this proje ....Titanium Alloy Scaffolds for Osseointegration Implant Materials.

The evolutionary structural optimization (ESO) is an Australian initiative, which has made a significant impact on modern structural optimization. In advanced materials areas, Australia has well-established infrastructure and world-class expertise. Exploitation of ESO to advanced materials design will be of "exclusive significance" to Australia. More importantly, the new material design technology will present to Australia an opportunity to lead in this rapidly-growing area, which will definitely underpin Australia's standing as a major contributor and developer in a global materials market. It is expected that fresh classes of futuristic materials can be developed in a cost-effective fashion and add great economic benefits to Australia.Read moreRead less
Cellular control mechanisms of matrix mineralization in the teeth of marine molluscs. These studies are significant as a foundation for the country's current focus on advanced materials and nanotechnology. The production of new materials is critically dependant upon understanding the crystallochemical control organisms, such as chitons and limpets, have over the precipitation of simple compounds, such as the calcium and iron oxides, phosphates and silica, often formed as nanoscale deposits.

These studies are significant as a foundation for the country's current focus on advanced materials and nanotechnology. The production of new materials is critically dependant upon understanding the crystallochemical control organisms, such as chitons and limpets, have over the precipitation of simple compounds, such as the calcium and iron oxides, phosphates and silica, often formed as nanoscale deposits. This study constitutes a systematic in situ exploration of the biomineralization processes that form these composite microstructures and as such will provide a new source of inspiration to the production of new biomaterials.Read moreRead less
Elastic softening of Ti alloys by plastic deformation for safer and more durable bone implants. This project will explore a critical factor that will form the basis of improving the biomechanical compatibility of titanium alloys for human bone implants. The outcomes will be a major step in optimising the design and development of human bone implants that will last a lifetime, avoiding the agony and risk associated with implant failure.
