Preparation of aluminum oxide/silicon carbide composite film
The invention discloses preparation of an aluminum oxide/silicon carbide composite film, which comprises the following steps: sintering an aggregate SiC powder and an auxiliary agent Al2O3 at a high temperature, then coating a silicon carbide porous ceramic support with an Al2O3 suspension, and sintering at a high temperature. The porosity and bending strength of the support are improved, and the prepared composite membrane has good thermal shock resistance.
本发明公开了一种氧化铝/碳化硅复合膜的制备，先高温烧结骨料SiC粉体和助剂Al2O3，然后再将Al2O3悬浮液涂覆于碳化硅多孔陶瓷支撑体上，并高温烧结。本发明的支撑体孔隙率，抗弯强度增加，所制得复合膜具有良好的抗热震性能。
