其中：铝的氧化物是指氧化铝粉，锆元素的矿石粉是指硅酸锆或者氧化锆，含镁元素的化合物粉是指碳酸镁、氧化镁、硝酸镁或者滑石粉，含铬元素的化合物粉是指氧化铬或者碳酸铬，含锰元素的化合物粉是指氧化锰或者碳酸锰，苏州土粉是指含硅元素的矿物质，含钡元素的化合物粉是指氧化钡或者碳酸钡。
本发明的一种质量稳定的低成本耐磨缸套的制备工艺如下：
①把按配方称量的原料球磨、喷雾干燥制成颗粒状的粉体；
②把颗粒状的粉体经过冷等静压成型(采用冷等静压成型设备成型)、高温烧结方式制成耐磨管；
③对经过高温烧结的耐磨管进行外圆和端面加工，将加工好的耐磨管放置到充分膨胀的金属外套内；
④对耐磨管内圆进行粗磨加工并抛光，从而制备出低成本耐磨缸套。
本发明制备方法简单，工艺合理，成品合格率高，生产成本大大降低，制备出的产品质量稳定可靠耐磨，产品使用寿命大大延长。
