Adding transition metals into the TiN films by arc ion plating (1) The hardnesses of theN films are higher that that of the TiN films, proving that the alloy hardening effect is a common phenomenon;(2) The structures of the alloyed films are determined by the added element properties such as covalent radius, electro negativity, free energy and lattice parameters of the MN compound;(3) theN film consists of a mixture of multi phases with high hardness but quite brittle, while the other MN films are composed of single phase with the fcc TiN structure and their hardesses, functions of the added amounts of the elements, manifest always a maximum at a certain M percentage.

一、将过渡金属M用电弧离子镀方法添加于TiN薄膜中：1。N薄膜硬度均高于TiN薄膜硬度，合金强化效应普遍存在；2。薄膜相结构决定于添加元素M的周期律信息，包括M的共价半径、电负性，及MN化合物的自由能、晶格常数等；3。N为多相混合结构，薄膜硬度高，但韧性差；其它N的相结构为TiN类型的单一fcc结构，薄膜硬度随M添加量变化并出现峰值；4。
