一、概述 碳和石墨由于能耐高温、耐腐蚀、导电、导热、耐磨等特性,已被广泛应用于许多重要工业部门,而使碳在一定条件下直接蒸发形成碳膜,则是碳在电镜研究试样时的一项重要应用。 众所周知,在使用电镜中对被观察的样品制作各种薄膜是必不可少的重要步骤,无 I. Overview Carbon and graphite have been widely used in many important industrial sectors because of their high temperature resistance, corrosion resistance, electrical conductivity, thermal conductivity, wear resistance and other characteristics, and carbon under certain conditions, the direct evaporation of the carbon film is carbon in the electron microscope An important application when studying specimens. It is well known that it is an essential and important step in the production of various films for the observed samples using electron microscopy.
