Two boride layers based on the FeB and Fe 2 B compounds are formed at the interface between an Fe-15Cr alloy and boron at 850-950uC and reaction times up to 12 h, with the average chromium content being around 8 at-% in the former and 12 at-% in the latter. Both boride layers reveal a pronounced texture. Diffusional growth kinetics of the layers are close to parabolic and can alternatively be described by a system of two non-linear differential equations. Microhardness values are 17?4 GPa for the FeB layer, 14?4 GPa for the Fe 2 B layer and 0?95 GPa for the Fe-15Cr alloy base. The dry abrasive wear resistance of borided alloy samples is around 45 times greater than that of non-borided ones.
