氧化铝陶瓷与石墨作为新型材料广泛应用于机械、电子、航空、石油化工、原子能等领域,二者具有一定的相似性能,其制备、结构及性能的研究已得到广大科技工作者的重视,但对其性能基础理论的对比研究还不够.对氧化铝陶瓷和石墨材料的耐磨性、疲劳、抗氧化性、形变、导电等性能进行了比较,指出在某些领域可用氧化铝陶瓷取代石墨材料.氧化铝陶瓷的高强度、耐磨、不易变形等性能能更好地满足工业加工,对节能环保具有重大意义.
Alumina ceramic and graphite are widely applied in machinery,electronics,aviation petrochemicals,atomic energy and other fields as new materials,scientist have been paying attention to the process of production and structure of them.There are many similar properties between them,but the research of foundational performance of the two is not enough.In this paper some petrochemicals of the two materials are discussed,such as wear resistances properties.fatigue performance,anti-oxidative ability,thermo-mechanical processing and electrical conductivity.It's pointed out that alumina ceramie can take the place of graphite in some fields.Alumina ceramic meets the needs of industrial process better because of its high strength,excellent wear resistence and so on,that is significat for energy saving and environmental protecting.
