【摘要】

：

以镍铝青铜为基体,运用冷喷涂技术制备镍铝青铜涂层.运用扫描电子显微镜、能谱分析仪、摩擦磨损试验机、自动显微硬度计分别研究了涂层的微观形貌、摩擦磨损性能和显微硬度分布,利用铁试剂法计算涂层孔隙率.研究表明：镍铝青铜颗粒可以较为致密地沉积在基体表面,并且颗粒大多以机械咬合方式与基体结合；由于加工硬化,接近界面的基体硬度明显提高,涂层硬度高于基体的硬度；涂层的平均摩擦系数为0.130,基体的平均耐磨系数

纳米复合结构硬质涂层的变形行为及其致硬机制研究

nc-ZrN/a-Si3N4纳米复合涂层的界面结构随复合相a-Si3N4含量的变化具有较为复杂的演变规律。在nc-ZrN/a-Si3N4纳米复合涂层中,随着复合相a-Si3N4含量的增加,ZrN与a-Si3N4界面结构将发生由柱状到无规形状的转变。上述变化导致传统材料强化机制(细晶强化、固溶强化、应力强化以及取向强化等)均难以合理解释纳米复合涂层硬度发生演变的本直。本文系统研究了nc-ZrN/a-

基于真空冷喷涂制备功能陶瓷薄膜

真空冷喷涂是一种在室温及真空条件下通过加速气体(He,N2,O2等)加速超细粉末粒子,使粒子以一定的速度撞击基体以及已沉积涂层,进而实现涂层制备的方法。作为一种新兴的陶瓷薄膜制备工艺,其具有沉积温度低,材料无相变,以及较高的沉积效率(通常可达几百纳米至几微米每分钟)等优点,可用于10μm以下陶瓷薄膜的高效率制备。真空冷喷涂已广泛应用于各个领域,在微电子领域,已用于制备高性能的铁电薄膜(PZT,Ba
