MAXCoat - Deposition and Properties of MAX phase functional films and coatings

MAX相被认为是一种具有有趣的物理化学性质的创新材料，几年前才成为研究的重点。基于其特殊的纳米层结构，它们将陶瓷和金属通常相互矛盾的特性结合在一种材料中。因此，它们的技术用途是功能陶瓷，引起了人们的极大兴趣。具有高达1300℃的高抗氧化性，良好的导电性和导热性，同时具有高强度，还具有延展性、抗冲击性和可加工性。膜或涂层等MAX相的生产很少被研究，但此类涂层具有巨大的技术潜力。因此，本项目的主要目标是获得可靠的MAX相涂层和薄膜的生产方法和策略，例如通过脉冲激光沉积(PLD)。然后对所生产的MAX薄膜的性能和可能的工业适用性进行了研究。重点介绍了它们作为极端电气条件(最高电压、最大电流)涂料的应用。此外，还将调查它们的生产和用于电子应用的性能。

MAX phases are seen as an innovative material with interesting physical and chemical properties, which get into research focus only a few years ago. Based on their special nanolaminate structure, they are combining the usually contradicting properties of ceramics and metals in a single material. Thus, their technological use are functional ceramics is attracting much interest in them. Having a high oxidation resistance up to 1300 C, a good electrical and thermal conductivity and high strength at the same time, they are also ductile, shock resistant and machinable. The production of such MAX phases as films or coatings is only barely investigated, but such coatings have a tremendous technical potential. Thus, it is the main goal of this project to obtain methods and strategies for the reliable productions of MAX phase coatings and films, e.g. by pulsed laser deposition (PLD). The produced MAX films are then investigated for their properties and possible industrial applicability. A focus is put in their application as coatings for extreme electricity conditions (highest voltages, highest currents). In addition, their production and properties for electronic applications will be investigated.
