Abstract:

以板状刚玉、氧化铝微粉、金属铝粉、金属锌粉为主要原料,以酚醛树脂为结合剂,制备Al2O3–Al–C滑板样品。研究了金属锌粉的引入对Al2O3–Al–C滑板显微结构和性能的影响。结果表明在450~1050℃热处理温度条件下,锌粉的引入改变了滑板中金属铝粉的反应进程,金属锌粉氧化后形成的氧化锌沉积在金属铝粉表面,改变了金属铝粉熔化、扩散和反应的进程,有利于材料在较低温度下形成金属结合,提高中温(600~1100℃)性能。锌粉的引入对材料显微结构有较大影响,900℃热处理3h后材料内部形成大量颗粒状、柱状和针状氮氧化物,1050℃热处理3h后材料内部形成大量碳化铝纤维,有利于材料性能的提高。
