This article attempts to understand better the origin of low friction and zero solid-solid adhesion observed on quasicrystals placed in vacuum. We present an ensemble of experimental data that allows us on the one hand to estimate the true surface energy of naked quasicrystals and approximants and on the other hand to point out a correlation with electronic densities of states.
