Objective
This project seeks to develop a low-cost, high strength, '-sialon ceramic of improved fracture toughness. This objective will be approached through the use of a dispersion toughening mechanism, with the incorporation within a '-sialon matrix of titanium nitride and/or carbide particles. The '-sialon matrix phase with its dispersed toughening phase will be derived, in powder form, from naturally occurring oxide materials by a single step carbothermal nitridation process. The sintering to full density of this 'composite powder' will then be optimized to yield a toughened ceramic matrix composite. The ready availability of a low-cost, high strength and relatively high fracture toughness ceramic, produced from low-cost raw materials, will assist the wider acceptance of these materials as substitutes for metallic engine materials in applications where higher efficiency and longer life are required.
The project seeks to develop a low cost, high strength, beta-sialon ceramic of improved fracture toughness. This objective will be approached through the use of a dispersion toughening mechanism, with the incorporation within a beta-sialon matrix of titanium nitride and/or titanium carbide particles. The beta-sialon matrix phase with its dispersed toughening phase will be derived, in powder form, from naturally occurring oxide materials by a single step carbothermal nitridation process. The sintering to full density of this composite powder will then be optimised to yield a toughened ceramic matrix composite. The ready availability of a low cost, high strength and relatively high fracture toughness ceramic, produced from low cost raw materials, will assist the wider acceptance of these materials as substitutes for metallic engine materials in applications where higher efficiency and longer life are required.
The synthesis of sialon based composite powder were optimised for various titanium nitride contents between 0 and 50 volume %. The shaping and the sintering of these powders has been achieved and the physical properties of the ceramic matrix composites are under investigation. The study of sintering mechanisms, sintering aids and microstructure developments will be achieved, as well as the manufacturing of large components and testing under realistic conditions of use.
