| 摘 要： | 为提高输送管道陶瓷内衬层的致密性及硬度等性能,拓展其应用,采用重力分离自蔓延高温合成(SHS)法,用(Al-Fe2O3-CuO)+SiO2复合铝热体系,制备了陶瓷内衬复合管.分析了添加剂纳米SiC对陶瓷层组织的影响.XRD分析表明,陶瓷层的主要成分为a-Al2O3,还有少量铁铝尖晶石FeAl2O4和硅线石Al2SiO5及SiC存在,SiC不改变陶瓷层的组织结构.纳米SiC的引入有效地抑制了基质晶粒生长和减轻了晶粒的异常长大,使得陶瓷层的硬度和致密性提高.

| Abstract: | Ceramic lining coating was prepared on the inside sur-faces of composite pipes by gravitational separation self-propaga-ting high - temperature synthesis ( SHS) with (Al-Fe2 O3 - CuO) plus SiO2 as the aluminothermic reactants, aiming at increasing the compactness and hardness of the lining and broaden its appli-cation scope. The effect of nano SiC additive on the phase compo-sition of the ceramic coating was investigated by means of X - ray diffraction. It was found that the ceramic coating was mainly com-p... |
