FIELD: machine building.
SUBSTANCE: on surface of top of turbine blade there are secured particles of silicon carbide (SiC) for forming abrading layer. On SiC-particles there is formed a self-recovering preventing layer out of metal or alloy facilitating formation of carbides, thermodynamically more stable, than SiC. Said metal or alloy is chosen from the group consisting of chromium (Cr), zirconium (Zr), titanium (Ti), tantalum (Ta), niobium (Nb), hafnium (Hf), yttrium (Y), scandium (Sc), thorium (Th), uranium (U), molybdenum (Mo), and also alloys of said elements. SiC-particles are fixed by their intrusion into a metal matrix or by high-temperature soldering with brasing metal or by laser weld.
EFFECT: produced self-recovering abrading layer possesses high resistance against destruction of SiC-particles at good cutting and grinding properties.
