摘要/Abstract

摘要： 为了拓展Ti₃AlC₂材料的应用领域,以Ti₃AlC₂粉为主要原料,采用有机前驱体浸渍法制备了Ti₃AlC₂质过滤陶瓷,研究Carbores P的加入量(加入质量分数为0~30%)对制备Ti₃AlC₂质过滤陶瓷的影响。结果表明:在埋碳条件, 1 100 ℃热处理后的Ti₃AlC₂质过滤陶瓷的主要物相为Ti₃AlC₂,但会有部分Ti₃AlC₂与CO气氛反应生成TiC和α-Al₂O₃。此外,随着Carbores P加入量的增加,制备Ti₃AlC₂质过滤陶瓷用浆料的黏度会随之增加,进而使得过滤陶瓷根筋直径增大,缺陷减少。并且,Carbores P的加入会改变热处理后Ti₃AlC₂粉之间的连结方式,使其连结更加紧密,增加Ti₃AlC₂质过滤陶瓷的常温耐压强度。当加入20%(w)Carbores P后,试样的常温耐压强度达到0.20 MPa。而进一步增加浆体中Carbores P加入量,会导致所制备的Ti₃AlC₂质过滤陶瓷经 1 100 ℃热处理后结构坍塌,这是由于Carbores P热分解导致过滤陶瓷体积收缩直至结构失稳。Carbores P添加量在20%(w)时,试样获得最好的力学性能。

Abstract: To expand the application of Ti₃AlC₂ materials,Ti₃AlC₂ ceramic filters were prepared via the polymer sponge replica technique using Ti₃AlC₂ powder as the main raw material.The influence of the Carbores P additions (0-30%,by mass) on the properties of the Ti₃AlC₂ ceramic filters was studied.The results indicate that the main phase of the ceramic filters is Ti₃AlC₂ after the heat treatment at 1 100 ℃ in a carbon embedded atmosphere.However,a portion of Ti₃AlC₂ reacts with CO to form TiC and α-Al₂O₃.Furthermore,with the Carbores P addition rising,the viscosity of slurry for preparing the ceramic filters increases,thus increasing the strut diameter of the ceramic filters and reducing defects.The Carbores P addition alters the bonding mode between Ti₃AlC₂ particles after heat treatment,resulting in tighter bonding and enhanced cold compressive strength of the ceramic filters.The sample with 20% Carbores P achieves cold compressive strength of 0.20 MPa.A further increase in the Carbores P addition causes structural collapse of the ceramic filters after the heat treatment at 1 100 ℃.This is attributed to the volume shrinkage of the ceramic filters during the thermal decomposition of Carbores P,which ultimately leads to structural instability.The sample with 20% Carbores P exhibits the optimal mechanical properties.
