我们提出了一个原子力显微镜研究纳米级的滑动摩擦金刚石，类金刚石碳，并在三个CrN薄膜具有不同的硬度通过不同的生长温度获得。对于氮化铬薄膜，我们表明，在摩擦系数的变化可以追溯到杨氏模量的变化。更一般地说，我们表明，所有的样品调查和无磨损制度，纳米级的摩擦系数是直接链接到杨氏模量。(C)2003年，美国物理学会。
We present an atomic force microscope study of nanoscopic sliding friction on diamond, diamond-like carbon, and on three CrN thin films with varying hardness obtained by different growth temperatures. For the CrN films, we show that the changes in the friction coefficient can be traced back to variations of the Young modulus. More generally, we show for all samples investigated and in wearless regime, that the nanoscopic friction coefficient is directly linked to the Young modulus. (C) 2003 American Institute of Physics.
