PROCESS OF PRECIPITATION OF COAT ON SUBSTRATE ( VERSIONS ) Russian patent published in 1999 - IPC

FIELD: electrolytic precipitation of coats. SUBSTANCE: process of precipitation of coat on substrate includes deposition of coat by way of electrolytic precipitation of metal matrix M₁ under current density less than 3.0 mA/sq.cm from bath containing particles of CrAlM₂ for coprecipitation of particles with matrix, where M₁ presents at least one element chosen from group composed of Ni, Co and Fe and M₂ - at least one element chosen from group composed of Y, Si, Ti, Hf, Ta, Nb, Mn, Pt and rare- earth elements. Precipitation forms layer with thickness 50 μ with bath load less than 40 g particles/l. EFFECT: enhanced resistance to oxidation and thermal fatigue. 24 cl, 4 dwg
