Abstract / 摘要

Titanium nitride (TiN) with high porosity (90%) was successfully in-situ prepared by a novel approach with the combination of carbothermic reduction nitriding method and replication template method. The microstructure of porous TiN prepared with different temperature and phenolic resin (PF) content were revealed by XRD, Raman spectrum, SEM, TEM, respectively. The results show that when the mass ratio of PF and TiO2 is 1:2 and the sintering temperature is 1850 ℃, porous TiN with high purity and ideal strength could be synthesized. In addition, the synthesis path and thermodynamic mechanism of porous TiN were analyzed by TG-DSC and Gibbs free energy calculation. The mechanical properties and corrosion resistance were preliminarily explored.
