A new lapping process for difficult-to-machine brittle materials. This project aims to address a timely bottleneck issue in the conventional lapping of difficult-to-machine optoelectronic brittle materials. An innovative chemically enhanced lapping technology for fabricating such materials is expected to reduce machined subsurface damage. This is significant because it would shorten the subsequent finishing process and minimise the manufacturing cost.

This project aims to address a timely bottleneck issue in the conventional lapping of difficult-to-machine optoelectronic brittle materials. An innovative chemically enhanced lapping technology for fabricating such materials is expected to reduce machined subsurface damage. This is significant because it would shorten the subsequent finishing process and minimise the manufacturing cost. Intended outcomes from this project also include an advanced machining theory and innovations in material removal characterisation. This breakthrough technology should benefit the design and fabrication of high performance electronic devices for energy, medicine and communication sectors with considerable impact on the Australian economy.Read moreRead less
Designed to last: novel gradient coatings for extreme environments. Hard coatings are frequently applied to equipment operating in harsh environments. Often such coatings are highly brittle and so fragile under stress, especially at high temperatures or in corrosive environments. Premature failure can affect safety and lead to negative economic and environmental consequences. The objective of this project is to combine bioinspired microstructural design with an emerging alloying concept to produ ....Designed to last: novel gradient coatings for extreme environments. Hard coatings are frequently applied to equipment operating in harsh environments. Often such coatings are highly brittle and so fragile under stress, especially at high temperatures or in corrosive environments. Premature failure can affect safety and lead to negative economic and environmental consequences. The objective of this project is to combine bioinspired microstructural design with an emerging alloying concept to produce a breakthrough in the development of engineering coatings; for example, overcoming the long standing trade-off between hardness and toughness. Such an innovative coating is expected to be highly durable in extreme conditions, and in so doing will help transform manufacturing, mining and desalination industries.Read moreRead less
High speed multi-channel discharge machining of difficult-to-cut materials. This project aims to develop a novel approach to high speed machining of difficult-to-cut materials by resolving the contradictory surface quality and machining efficiency problem with a new theory. It is expected to advance the fundamental knowledge of electrical machining.

This project aims to develop a novel approach to high speed machining of difficult-to-cut materials by resolving the contradictory surface quality and machining efficiency problem with a new theory. It is expected to advance the fundamental knowledge of electrical machining. The outcomes are new machining theories, novel methods and models of using multiple low energy sparks which occur nearly simultaneously for high speed machining of a wide range of advanced materials. It should significantly increase machining speed and thus dramatically reduce the costs of producing products such as titanium medical implants, alloyed engine components and new cutting tools which are vital for the biomaterials, aerospace and manufacturing industries.Read moreRead less
Ductile grinding mechanism and technology of brittle single crystals. This project aims to develop a fundamental understanding of the removal mechanics of emerging brittle single crystals under grinding-induced loading. A successful outcome will not only develop a new theoretical model for predicting the ductile removal regime of this class of difficult-to-machine materials, but their cost-effective ductile grinding processes will also be generated.

This project aims to develop a fundamental understanding of the removal mechanics of emerging brittle single crystals under grinding-induced loading. A successful outcome will not only develop a new theoretical model for predicting the ductile removal regime of this class of difficult-to-machine materials, but their cost-effective ductile grinding processes will also be generated. It will address a longstanding bottleneck productivity issue in advanced manufacturing. The breakthrough technology developed in the project is expected to significantly benefit a number of industrial sectors for the fabrication of more affordable high-performance devices including mobile phones, light-emitting diodes, solar cells, sensors, and laser systems.Read moreRead less
