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.

Studies on metal dusting : reaction mechanisms and their control. Gases which are supersaturated with carbon can react at high temperatures with steels and nickel-base alloys to destroy them, producing a dust of carbon plus metal and/or metal carbides. The mechanism is not properly understood, and the rate of the process impossible to predict. This program will dissect the mechanism using kinetic studies and electron microscopy of precisely located parts of the reacting system. Ways of controll ....Studies on metal dusting : reaction mechanisms and their control.

Surface mechanical attrition treatment will be used to generate nanometer-sized grains in the surface layer of engineering magnesium alloys, and therefore activate the surface of this material. Together with the use of efficient activators, the project will develop a novel low temperature surface alloying technique to significantly improve the wear and corrosion resistance of magnesium alloys without changing the substrate properties. Microstructural features and the wear and corrosion resistance of the ultrafine-grained surface layer will be examined. In addition, it may be possible to combine the surface alloying process with the conventional ageing process together in order to save energy.Read moreRead less
Controlling corrosion of steel by carbon dioxide-rich gases at high temperatures. A growing difficulty for Australia is the need to reduce carbon dioxide (CO2) emissions whilst maintaining the economic advantages of coal fired power stations. Technologies for capturing CO2 from these stations are being developed, but inevitably involve the need to handle hot CO2-rich gases. These are surprisingly corrosive to the materials of which power stations are constructed, in a way which is not fully unde ....Controlling corrosion of steel by carbon dioxide-rich gases at high temperatures.

These are surprisingly corrosive to the materials of which power stations are constructed, in a way which is not fully understood. This project aims to achieve this understanding, and to provide the basis for future alloy design.Read moreRead less
