Description The paper focuses on the problem of low adhesion of plasma sprayed coatings to the
substrate. The subsequent laser treatment modes and their influence on the coatingsubstrate
interface were studied. This allows to decrease the level of met-stability of
the coating, thus decreasing its hardness down to 11–12 GPa on the surface and to
about 9 GPa on depth of 400 µm. The redistribution of alloying elements through
solid and liquid diffusion improves mechanical properties and rises the adhesion up
to 450 MPa after remelting and up to 90–110 MPa after laser-aided thermal cycling.
At the same time, remelting of coating helps to decrease its porosity down to 1%. The
obtained complex of properties also allows to improve wear resistance of coatings and
to decrease friction factor.
