Abstract

Vorgeschlagen wird ein Verfahren zur Herstellung von Komposit-Spritzschichten auf Zylinderlaufflächen von Zylinderkurbelgehäusen. Bei dem Verfahren wird ein inertes Gas (16) oder ein Gasgemisch, bei dem mindestens ein Bestandteil ein inertes Gas ist, zwischen einer Kathode (20) und einem als Anode dienenden Draht (30) mittels eines Lichtbogens gezündet und ionisiert, und das sich ausbildende Plasma aufrechterhalten, wobei der Draht (30) aufschmilzt. Um differenziertere technische Eigenschaften des durch thermisches Spritzen auf das Substrat aufgebrachten Materials zu erreichen, wird zusätzlich ein Transport- und Fokussiergas (18) auf den Plasmastrahl gerichtet, und es werden in mindestens zwei aufeinander folgenden Durchläufen Schichten (5.1, 5.2, 5.3) mit unterschiedlichen Zusammensetzungen und Eigenschaften auf dem Substrat (2) sich überdeckend abgelagert, wobei von Durchlauf zu Durchlauf die Zusammensetzung des Transport- und Fokussiergases (18) verändert und so die Ausbildung der einzelnen Schichten hinsichtlich ihrer Mikrostruktur und Porenbildung unterschiedlich beeinflusst wird.

It proposes a method for producing composite sprayed layers on cylinder surfaces of cylinder crankcases. In the method, an inert gas (16) or a gas mixture in which at least one component is an inert gas is ignited and ionized between a cathode (20) and an anode wire (30) by arc, and the forming one Maintain plasma, wherein the wire (30) melts. In order to achieve more differentiated technical properties of the material applied by thermal spraying onto the substrate, a transporting and focusing gas (18) is additionally directed to the plasma jet, and layers (5.1, 5.2, 5.3) with different thicknesses are formed in at least two successive passes Compositions and properties on the substrate (2) are deposited overlapping, whereby from one run to the next the composition of the transport and focusing gas (18) changes and thus the formation of the individual layers is differently influenced with regard to their microstructure and pore formation.
