摘要: Metal-containing amorphous hydrogenated carbon films are of high interest for industrial applications because their excellent frictional properties, abrasive wear resistance and electrical conductivity, which can be adjusted in a range 10–12 orders magnitude. In order to get insight into the mechanical properties it is necessary study nanostructure films. The structure consists small nanometer sized metallic or carbidic particles, embedded three dimensional hydrogen-carbon matrix. Anomalous angle X-ray scattering (ASAXS) scanning tunneling microscopy (STM) have been used determine size- distance-distributions particles as function metal content. Problems restrictions both methods will discussed. Furthermore capabilities probe techniques distinguish different materials on scale (material contrast) studied employing barrier height imaging (dI/dz) friction force microscopy.
