METHOD OF APPLYING MULTICOMPONENT COATING BY ELECTRIC ARC METALIZATION Russian patent published in 2018 - IPC B05B7/22 C23C4/131 C23C4/06 

FIELD: technological processes.

SUBSTANCE: at least, two metallizers with two wires in each metallizer are used. Metallizers are positioned at an angle α1 in the range of 35 to 45° between their axes and at an angle α2 in the range of 18 to 22° to the normal to the machined surface so that the zone of the electric arc is located at a distance of 130 to 150 mm from the surface to be treated. In the metallization process, the flows of a dispersed mixture of metals converge to a point on the surface to be treated. Wires of Cu and Sn composition are used with a diameter of 1.5-2.5 mm, while choosing wires with a component ratio, which allows to obtain an optimal composition coating as a result of mixing components of all wires.

EFFECT: regulating the physico-chemical composition of the applied metal antifriction coating and obtaining a heterogeneous complex composition with improved properties using a common type of the metallizer.
