摘要
We present a novel method for direct measurement of both internal and external friction and adhesion using the atomic force microscope (AFM). The background for the granule friction and adhesion measurements is given and we demonstrate the power of this novel technique on silicon nitride granules. The AFM measurements clearly illustrate the importance of humidity and binder concentration on both friction and adhesion, which is of direct relevance for the pressing performance.
