[0018] Example 1: A kind of Ta 2 AlC-Ta 4 AlC 3 The preparation method of the composite material includes the following steps:
[0019] (1) Using tantalum powder, aluminum powder and tantalum carbide powder as raw materials, according to the molar ratio of Ta:Al:TaC=1:1.4:1 and adding 10% mass fraction of tantalum carbide powder ingredients;
[0020] (2) Put the above-mentioned ingredients into a ball mill tank and wet mix for 15 hours on a planetary ball mill;
[0021] (3) Dry the mixture with a rotary evaporator, and then place it in a graphite abrasive tool for pre-compression, and the pre-compression pressure is 20Mpa;
[0022] (4) Place the mold in a spark plasma sintering furnace, under the protection of Ar gas, heat it to 1500°C at a heating rate of 200°C / min, and hold it for 5 minutes at a pressure of 500MPa. After the heat preservation is over, the furnace is cooled to room temperature, and Ta is obtained 2 AlC-Ta 4 AlC 3 Composite bulk ceramics.
