Durch das Zentrifugalschleudergießen oder heißisostatische Pressen der genannten pulverförmigen Eisenbasishartlegierung werden auf der inneren Bohrungsfläche der Metallzylinder dichte Panzerschichten erzeugt, die mit dem Zylindergrundwerkstoff metallurgisch verbunden sind und überraschenderweise eine wesentlich gesteigerte Verschleißbeständigkeit aufweisen. Durch den hohen Gehalt an Vanadium und Kohlenstoff werden nämlich vanadiumhaltige arteigene Metallkarbide in so großer Menge ausgeschieden, dass gegenüber herkömmlichen bekannten Hartlegierungen zum Zylinderinnenpanzern eine wesentlich höhere Abrasivverschleißbeständigkeit erzielt wird. Durch die karbidbildenden Metalle Molybdän, Wolfram o. a. wird die Dichte der Metallkarbide so eingestellt, dass während des Aufbringens der Innenpanzerung keine Separation der Metallkarbide in der Restschmelze entsteht. Die Metallkarbide sind damit über die gesamte Dicke der Beschichtung gleichmäßig verteilt, d. h. es werden gleiche technologische Eigenschaften über die gesamte Panzerschichtdicke erreicht.By the centrifugal centrifugal casting or hot isostatic Pressing said powdery Iron base age alloys are used on the inner bore surface of the Metal cylinder produces dense armor layers, which coincide with the cylinder base material metallurgically connected and surprisingly essential increased wear resistance exhibit. Due to the high content of vanadium and carbon namely Vanadium-containing species-specific metal carbides in such a large amount excreted that compared to conventional known Hard alloys to the cylinder inner armor a much higher abrasive wear resistance is achieved. By the carbide-forming metals molybdenum, tungsten o. a. The density of the metal carbides is adjusted so that during the Applying the inner armor no separation of the metal carbides in the residual melt arises. The metal carbides are thus on the entire thickness of the coating evenly distributed, d. H. it will same technological properties over the entire armor layer thickness reached.
