The paper investigates the influence of magnetic treatment on the destruction mechanism of detonation coatings of WC-Co and Fe-Al systems on the steel substrate at bend test. We establish that magnetic treatment enhances mechanical properties of the system "coating--substrate". The plastic deformation of the system raises from 0,15 % to 0, 35 % in the cracking moment. Tensions developed at the destruction moment increases from 700 to 1300 MPa for VK-15 hard-alloy, while for Fe3Al alloy deformation increases from 0,06 % to 0, 2% and tensions raises from 214 to 582. The enhancement of properties is caused by improving of the adhesion quality on the "coating--substrate" boundary as a result of elements redistribution at magnetic treatment.
