Structural characterisation and strength evaluation of spray formed ceramic composite near-net shapes

This paper explores the characteristics of spray formed near-net shaped ceramic composite. Alumina–titania composite (Al2O3 60 wt.%; TiO2 40 wt.%) was spray formed using a plasma dyne atmospheric facility. Micrographs of as-sprayed samples are presented, along with micrographs of samples post-heat treated at different temperatures. EPMA profiles were determined and XRD phase analysis was carried out. Young’s modulus, strength and hardness of the samples was determined.
