FIELD: metallurgy.
SUBSTANCE: metal surface is covered with cermet coating or insertion. Cermet coating or insertion contains from approximately 30 to approximately 95 vol % of a ceramic phase and a metal binding phase. Cermet coating or insertion has index of erosion resistance at least 5.0 and fracture strength K1C at least 7.0 MPa m1/2.
EFFECT: procedure facilitates high resistance to high temperature erosion and corrosion combined with high fracture strength.
