    Amorphous B4C films were prepared by magnetron sputtering of the hot-pressed B4C target in different regimes. Hardness, intrinsic stress and film structure were investigated in dependence on the annealing temperature in air.Changes in the film structure and composition were investigated by Raman spectroscopy,confocal microscopy, and electron probe microanalysis. It has been shown that an annealing at 500 °C for 1 h leads to stress reduction, slight thickness decrease and increase of film hardness. However already at 600 °C the film oxidation proceeds very intensively with formation of the phases of boron oxide and amorphous carbon in the surface layer. The thickness of the film decreases quickly.
