Feasibility Analysis of Self-Reactive Spray Forming TiC-TiB2-Based Composite Ceramic Preforms
A new near-net-shape technology,namely,self-reactive spray forming,to prepare ceramic preforms with low cost was proposed by combining the self-propagating high-temperature synthesis (SHS) with the metal spray forming.The feasibility of the technology was illustrated.And TiC-TiB2 -based structural ceramic was prepared by the new technology.The microstructure of the self-reactive spray formed preforms was analyzed.It was shown that the self-reactive spray formed preforms are composed of four kinds of structure,which takes on the characteristics of rapid solidification.They are griseous continuous base phase TiC0.3N0.7,black columnar grain TiB2 with the size of 100nm-1 μm,white by-product phase TiO2 distributing along the boundary of the base phase,and a few of black anomalous pores respectively.
