【摘要】 用离子束增强沉积法（IBED）在硅及铜基体上沉积了TiB2薄膜，研究了轰击离子束能量和束流对薄膜的微结构及力学性能的影响。用俄歇电子谱（AES）分析了膜的成分及其界面状况，用X射线衍射（XRD）研究了膜的微结构，并测定了膜的硬度及进行了膜的高温氧化试验。结果指出：（1）离子束轰击使薄膜晶化，从而影响到膜的硬度及抗高温氧化性能；（2）离子束增强沉积的二硼化钛薄膜是一种耐高温氧化的高硬膜。更多还原

【Abstract】 This paper introduces the ion beam enhancement deposition(IBED) of TiB2 thin films on Si and Cu, and the results of film properties and microstructure research. Effects of the energy and beam current of the bombardment ion beam on the microstructure and mechanic properties of films have been investigated. The composition and interface of the films were analyzed by AES. Microstructures of the films were analyzed by XRD. The microhardness of the flims was determined and the properties of high temperature oxidation were tested. The results show that ion beam bombardment during deposition can promote the crystallization of thin films and then has an effect on the microhardness and oxidation resistance. The TiB2 film deposited by IBED is a high-hardness film with good oxidation resistence against high temperature.更多还原
