The radiation stability of AlN polycrystals with wurzite structure and BN polycrystals with hexagonal and rhombohedral structure irradiated with Ar⁺ and Kr⁺ ions was studied experimentally and by computer simulation for normal and oblique incidence. Absolute values of the sputtering yield from AlN were measured for the first time and used to choose the binding energy in the simulation model. Radiation strength of BN to ion irradiation is much higher than that of AlN. The effect of low-energy electron irradiation on surface structure was studied. It was found that, in contrast with BN, the surface of AlN is not modified by electrons.
