The availability of suitable materials is a driver of new technologies. We will develop a new class of ternary and quaternary alloys with nanolaminate structures at the atomic scale using a combination of theoretical modeling, novel thin film synthesis and advanced characterization methods. The nanostructure of these materials is expected to promote a rare combination of metallic and ceramic like properties, such as low friction, high mechanical strength, resistance to heat shock, fracture, corrosion and oxidation, up to very high temperatures. Careful characterisation of the growth process and structure-property relationships will allow us to develop methods of tailoring the property mix for operation in harsh environments.

合适材料的可获得性是新技术的驱动力。我们将结合理论建模、新颖的薄膜合成和先进的表征方法，在原子尺度上开发一类新的具有纳米层状结构的三元和四元合金。这些材料的纳米结构有望促进罕见的金属和陶瓷性质的结合，如低摩擦、高机械强度、耐热震、断裂、腐蚀和氧化，直到非常高的温度。对增长过程和结构-财产关系的仔细描述将使我们能够开发出适合在恶劣环境下运营的财产组合的方法。
