Recycling of Aluminum and Titanium Chips by Microwave Augmented SHS

摘要

Recycling of titanium and aluminium chips to manufacture wear and corrosion-resistant intermetallicbasedcoatings is achieved by microwave assisted Self Propagating High Temperature Synthesis(SHS). A multi-physics model implementing both reaction kinetic and microwave heating and heattransfer has been developed in order to optimize the synthesis condition. Numerical simulationallowed to investigate the preferable applicator geometry and to quantify the excess heat generated,which could be useful to promote further reactions with an iron-based substrate, thus realizingintermetallic-coated steel-based products.
