摘要：Ti2AlC belongs to the so-called "MAX" phases ternary carbides material group, which possess a useful combination of both metallic and ceramic properties. Its excellent oxidation and corrosion resistance indicate that porous Ti2AlC has remarkable application prospects in LHP (loop heat pipe) wicks. In this study, Ti+Al+TiC and Ti+Al+C powder mixtures are employed as starting powders respectively and effects of different volume fraction of pore former on properties of porous Ti2AlC were studied. The experimental results indicate that the reaction process of Ti+Al+TiC system is more stable than that of Ti+Al+C system. The porosity of the porous Ti2AlC through sintering Ti+Al+C powder mixtures are relatively large, which is easy to form through holes, increases capillary pressure and improves the pumping capacity of the wick.
