Preparation of Ti₂AlN Porous Ceramics by Organic Foam Impregnation Process

Abstract:

In this work, Ti₂AlN porous ceramics was made by the organic foam impregnation. High-purity Ti₂AlN powder was sintered at 1300 °C for 2 h of Ti/1.1Al/TiN in stoichiometric proportion. The slurry solids of organic foam impregnation method was 60 %, using 2 % polyacrylamide as dispersant, 0.5 % polyvinyl alcohol as a binder and 0.5 % ethanol as defoaming. The polyurethane sponge was pre-treatment for 6 h with 15 % NaOH solution and soak for 24 h with 4 % of carboxymethyl cellulose (CMC) solution. Through the pre-treatment, the polyurethane sponge hangs pulp quantity is higher, and the percentage of plugged hole is the lowest. The Ti₂AlN porous ceramics is relatively uniform open holes with three-dimensional skeleton structure. This study can generate to the studies of the preparation of the mesh structure products and the preparation of ceramic matrix composites by pressureless infiltration process.
