Research on High-temperature Tribological Behaviors of TiAlN Hard Coatings by Physical Vapor Deposition

Abstract

TiAlN是一种生产工艺成熟、加工性能优异,且极具代表性的硬质耐磨涂层,在切削刀具表面的应用非常广泛。相对于传统的TiN等金属氮化物涂层,TiAlN涂层最突出的特点是其在高速切削和高温氧化条件下表现出来的优异摩擦学性能,国内、外研究者们对此特别关注,并做了大量的相关研究,但其中的机理性研究尚不充分,且结论的可重复性不高。弄清TiAlN涂层在高温氧化、负载条件下的磨损机理,不仅可以给TiAlN涂层生产工艺优化和涂层产品质量提高提供指导,而且对深化涂层摩擦学理论基础也具有重要意义。 本文运用多弧离子镀(MAIP)沉积工艺,在商业化设备中分别制备了中、高Al含量的两种TiAlN涂层(即Ti0.46...TiAlN coating has been widely applied on cutting tools because of its highly developed production technology and excellent machining performance,as one of the most representative protective coatings.
