Abstract

Um Hartstoffe bei kurzen Reaktionszeiten (rd. 1 - 10 ms) insbesonders auf dem Flugweg der Spritzteilchen in kosten­ günstiger Weise während des Lichtbogenspritzens erzeugen zu können, werden exotherm reagierende pulverförmige Ausgangs­ stoffe mit Hartstoffen und/oder metallischen und nicht­ metallischen Elementen und/oder Vorlegierungen in Pulver­ form zunächst mit organischen bzw. anorganischen Binde­ mitteln versetzt und hieraus durch Sprühtrocknung bzw. Agglomeration Verbundpulver hergestellt und anschließend zur Füllung von Hohldrähten verwendet.
Infolge des hierdurch gegenüber einer losen Pulvermischung verringerten Reaktionsweges und dem gleichzeitigen Frei­ setzen von Energie aufgrund stattfindender exothermer Reaktionen, wird der Hartstoffanteil in den gespritzten Schichten signifikant erhöht. In order to be able to produce hard materials with short reaction times (approx. 1 - 10 ms), especially on the flight path of the spray particles in a cost-effective manner during arc spraying, exothermic powdery starting materials with hard materials and / or metallic and non-metallic elements and / or master alloys in powder form, first mixed with organic or inorganic binders and made of composite powder by spray drying or agglomeration and then used to fill hollow wires.
As a result of the reduced reaction path compared to a loose powder mixture and the simultaneous release of energy due to exothermic reactions taking place, the proportion of hard material in the sprayed layers is significantly increased.
