Thermal spraying process and thermally sprayed layer and coated connecting rod bearing

摘要

A method for electric arc - wire spraying for the deposition of layers of material, in particular a low-friction, wherein the spraying device at least an oxygen-containing sputtering gas and are fed to a fuel gas, which in a combustion chamber in the immediate vicinity of or behind the arc under the action of a part of the oxygen-containing atomizer gas is burned up and after the discharge from the nozzle generates a flame jet characterized in that, by oxidation of the metallic components of the spray wire at least on the surface of the spray droplets is formed a metal oxide layer.
