本文实验采用磁控溅射镀膜的原理先在玻璃基底上沉积CuZr薄膜，经探究后改用单晶硅进行实验，来系统研究组元成分、溅射气压和冷却时间对薄膜的非晶结构的影响，并且对用纳米压痕技术测定纳米薄膜的硬度和弹性模量进行了文献调研。
研究结果表明：在一定范围内，Cu含量越少，越容易形成非晶；溅射压强越低，越容易形成非晶；冷却时间越久，形成非晶效果越好。

Title Cu-Zr amorphous thin films was prepared by magnetron sputtering and researched mechanics Performance
Abstract
By trying the element composition, improving experimental parameters,the film preparation is more easily to get an amorphous structure than the BMG. Learning preparation of amorphous films is meaningful for research on BMG research and useful to understand the nature of law and crystallization of amorphous alloys.
In this paper,Cu-Zr binary amorphous alloy thin films were prepared on Si substrates by magnetron sputtering technique. After explore we switched to the single crystal silicon to do experiment, by this way to study the influence of component composition , sputtering pressure and cooling time to film amorphous structure systematically, and do some literature survey of nanoindentation by measuring the hardness and elastic modulus.
The results show that : in a certain range, the less the Cu ratio is, the more easy to form an amorphous; the lower the pressure is, the more easy to form an amorphous; the longer cooling time, the better the results.
Keywords Amorphous films magnetron sputtering CuZr alloy nanoindentation
