The aim of this Linkage Project is to provide viable material solutions to address the health problem of Lead-contamination in drinking water arising from Leaded-brass plumbing products and the impact Lead-removal from brass will have on the brass industry. In order to achieve this, this project engages leading multidisciplinary researchers along with Australian and international industry partners from across the brass industry supply and sales network. This project seeks to identify and harness the key material-product attributes required to develop and implement new, lead-free alloy alternatives that meet health-compliance, production and commercial viability, that offer benefits across the industry network and health benefits to society.Read moreRead less
High-efficient abrasive waterjet machining of complex curved surfaces. This project aims to develop an abrasive waterjet process technology that is expected to increase the manufacturing efficiency by 4 times for complex curved surface structures such as the integral impellers and blisks used in turbine machines and aeroengines. It will also explore the science associated with the energy dissipation process for ultrahigh velocity abrasive waterjets and the curved surface generation process by th ....High-efficient abrasive waterjet machining of complex curved surfaces. This project aims to develop an abrasive waterjet process technology that is expected to increase the manufacturing efficiency by 4 times for complex curved surface structures such as the integral impellers and blisks used in turbine machines and aeroengines. It will also explore the science associated with the energy dissipation process for ultrahigh velocity abrasive waterjets and the curved surface generation process by the impact of a cloud of numerous particles. The intended outcome will break a technological barrier and make it entirely possible for the wide use of integral impellers and blisks in airplanes to significantly increase fuel efficiency. The economic, social and environmental benefit is expected to be enormous.Read moreRead less
Enhancing and modelling the abrasive waterjet impact and erosion process. This project aims to understand and improve the ultrahigh pressure abrasive waterjet (AWJ) impact process. The current AWJ machining technology transfers less than 20% of the jet energy to the workpiece, mainly due to the damping effect of a stagnant layer at the jet impact site. This project attempts to remove this effect using ultrasonic vibration and explore the new impact micromechanics under the coupled effect of part ....Enhancing and modelling the abrasive waterjet impact and erosion process. This project aims to understand and improve the ultrahigh pressure abrasive waterjet (AWJ) impact process. The current AWJ machining technology transfers less than 20% of the jet energy to the workpiece, mainly due to the damping effect of a stagnant layer at the jet impact site. This project attempts to remove this effect using ultrasonic vibration and explore the new impact micromechanics under the coupled effect of particle impact and workpiece vibration. The expected outcome is a new AWJ technology for efficient, multi-scale machining, and to increase industry’s capability in fabricating high-integrity products.Read moreRead less
