| 中文摘要: |
| 利用有机泡沫浸渍法制备Ti2AlN多孔陶瓷，研究了聚氨酯海绵表面改性对陶瓷挂浆量的影响。通过对不同浓度的NaOH预处理后的海绵增重、坯体堵孔率分析表明，浓度为15%的NaOH对聚氨酯海绵的挂浆量最好；扫描电镜研究发现，聚氨酯海绵用15%NaOH溶液浸泡4小时之后，再用羧甲基纤维素(CMC)预处理24小时，海绵挂浆效果最佳。 |

| Ti2AlN porous ceramics had been prepared by using organic foam impregnation process, and studied the polyurethane sponge surface modification affecting the quantities of hanging ceramic slurry. After pretreatment by different concentrations of NaOH sponge weight gain, body blocking rate analysis showed the best of the concentration of 15% NaOH to polyurethane sponge hang pulp quantities. Scanning electron microscopy (SEM), the study found the polyurethane sponge soaked with 15% NaOH solution after 4 hours, then used carboxymethyl cellulose (CMC) pretreatment for 24 hours, sponge hang pulp effect was the best. |
