The influence of magnetic treatment on the mechanical properties of WC–Co hardmetal detonation spray coatings is studied. The type and size of internal stresses in coatings are determined. It is established that treatment in the magnetic field considerably decreases stresses (by 50–60%) but has no effect on the stressed state of the coating–substrate system. It is shown that magnetic properties of the substrate material have no influence on the results of magnetic treatment in our case.
