三元层状可加工导电MAX相陶瓷研究进展

Progress in Machinable and Electrically Conductive Laminated Ternary Ceramics(MAX Phases)

三元层状可加工导电陶瓷是一类键合具有明显各向异性的层状碳化物或氮化物,它通常又被称为MAX相陶瓷。MAX相陶瓷具有优良的可加工性,良好的导电、导热能力,可观的高温强度,同时还具有良好的热稳定性、抗氧化性、抗热震性和耐腐蚀性能。本文介绍了MAX相陶瓷的结构、性能以及制备方法和应用前景。

The laminated ternary ceramics(MAX phases)are layered carbides/nitrides withremarkable bonding anisotropy.They have excellent machinability,good electrical and thermalconductivity,and respectable high-temperature strength.They are also advantageous in good thermalstability,oxidation resistance,thermal shock resistance and chemical corrosion resistance.Thepresent paper introduces MAX phases in terms of structure,property,preparation method anddevelopment trend.
