METHOD FOR PRODUCING MACHINE PARTS HAVING AT LEAST ONE SLIDING SURFACE Russian patent published in 2006 - IPC C23C4/12 C23C4/06 

FIELD: manufacture of machine parts such as piston rings and(or) pistons and(or) engine cylinder sleeves, preferably two-cycle Diesel engines with large working volume having at least one sliding surface.

SUBSTANCE: method comprises steps of applying coating on sliding zone by thermal deposition onto basic material; forming coating due to aggregation of aluminum bronze and at least one other material not alloyed with it; depositing coating inclusions more rigid in comparison with other coating materials in the form of powder non-melt during deposition together with other materials melt for deposition; in order to create stream for deposition, melting at least one hollow wire including in its cavity powders of carbides and(or) oxides forming inclusions non-melting at deposition. Stream created for deposition includes air and(or) nitrogen and(or), argon and(or) helium, and(or) hydrogen.

EFFECT: simplified process of coating deposition, reliable metering and uniform distribution of inclusions in coating.
