In order to estimate the erosion rates of some plasma facing component materials, the sputtering yields of Mo, W and deuterium-saturated Li bombarded by fusion charged particles are calculated by application of new sputtering physics description methods based on the bipartition model of ion transport theory. The comparisons with Monte Carlo calculation and experimental results are made. These data might be useful to estimate the lifetime of plasma facing components and to analyse the impurity level in core plasma of fusion reactors.
