Net-shape manufacturing of sialon ceramics

[摘要] A number of manufacturing techniques, including 3D printing, cold and hot isostatic pressing, have been used in order to assess whether it is possible to produce net shape components from Syalon 050.The green density, sintered density and porosity of samples were measured to find the optimum parameters required to produce dense and homogeneous components. 3D printing has been used with different binder content to find the optimum parameters, but the level of bonding for all conditions was inadequate and samples disintegrated during binder removal process. Cold Isostatic Pressing samples were also made using different pressures, and the sample with highest density was sintered. It was possible to obtain fully dense samples by sintering. Four point bending tests have been carried out on fully sintered samples.
