FIELD: machine building.
SUBSTANCE: invention relates to coating application method by thermal spraying, in particular, to coating application on cylinder sleeve internal surface by plasma-arc sputtering. Method involves coating application from alloy on cylinder inner surface by means of plasma sputtering device rotation around wire and device movement along cylinder longitudinal axis, so, that coating is applied on cylinder inner surface along circumference and along cylinder axial direction, wherein device comprises plasma torch nozzle, to which plasma gas is supplied, and auxiliary nozzles, to which carrier gas is supplied, carrier gas and/or plasma gas flow rate change is carried out with help of control element depending on device axial position inside cylinder, besides, first lower gas flow rate is carried out in upper dead point area and in lower dead point area, and second, higher gas flow rate, is in center area and upper area at engine cylinder sleeve cover, wherein upper dead point area is borders to upper area at cover and to center area, and cylinder lower dead point area is borders to center area.
EFFECT: coating application by thermal spraying.
