  Verfahren zur partiellen Materialveredelung der Oberfläche von Metallgegenständen. 



   Bei Ausübung des Verfahrens nach dem Stammpatente Nr. 80064 kann bei der Veredelung von Grundmetallen, deren Schmelzpunkt wesentlich unter dem des aufzutragenden Metalles liegt, wie z. B. bei Gusseisen und Bronze, durch Unachtsamkeit des Schweissers pine Verbrennung bzw. Oxydation dieser Grundmetalle eintreten. Man kann nun die kohlenstoffärmeren Eisen, wie Schmiedeeisen oder Stahl, bei welchen diese Gefahr infolge ihrer höheren Schmelzpunkte nicht besteht, benützen, um die Unabhängigkeit von der manuellen Geschicklichkeit des Schweissers, insbesondere bei der Veredelung von Gusseisen, zu erreichen. indem man dieselben als Hilfsschicht mittels der in der Technik gebräuchlichen elektrischen oder autogenen Schvreissmethoden zuerst auf das Gusseisen in dünner Schicht aufschweisst und dann erst hierauf die Veredelung nach dem Verfahren des Stammpatentes ausführt. 



   Bei Bronzen oder ähnlichen Legierungen eignen sich schmiedbare Eisen oder Stahl als 
 EMI1.1 
 seits derartige Grundmetalle vielfach Eisen nur in geringerem Masse aufnehmen, wodurch ein untrennbares Anhaften der Hilfsschicht auf der Unterlage gefährdet werden könnte. 



  Hier können Nickel uud Kobalt oder Legierungen, die diese Metalle in entsprechenden Verhältnissen enthalten, mit vollkommenem Erfolge als Hilfsschicht verwendet werden. Diese Metalle oder deren Legierungen werden, im Gegensatze zu Eisen, von allen gebräuchlichen Bronzen gut aufgenommen und gewährleisten dadurch eine verlässliche Vereinigung mit der Unterlage.

  Process for partial material refinement of the surface of metal objects.



   When exercising the process according to the parent patent no. 80064, when refining base metals whose melting point is significantly below that of the metal to be applied, such as B. in cast iron and bronze, if the welder is inattentive, combustion or oxidation of these base metals occurs. You can now use the lower-carbon irons, such as wrought iron or steel, for which this risk does not exist due to their higher melting points, in order to achieve independence from the manual dexterity of the welder, especially when refining cast iron. by first welding the same as an auxiliary layer onto the cast iron in a thin layer by means of the electrical or autogenous welding methods customary in technology and only then performing the finishing according to the method of the parent patent.



   For bronzes or similar alloys, malleable iron or steel are suitable as
 EMI1.1
 On the other hand, such base metals often only absorb iron to a lesser extent, which could jeopardize the inseparable adhesion of the auxiliary layer to the substrate.



  Here nickel and cobalt or alloys containing these metals in appropriate proportions can be used as an auxiliary layer with complete success. In contrast to iron, these metals or their alloys are well absorbed by all common bronzes and thus guarantee a reliable bond with the substrate.

PATENT-ANSPRUCH : Verfahren zur partiellen Materialveredelung der Oberfläche von Metallgegenständen nach dem Stammpatente Nr. 80064, dadurch gekennzeichnet, dass Gegenstände aus Gusseisen vor der Veredelung mit einer Hilfsschicht aus schmiedbarem Eisen oder Stahl oder Stahllegierungen in bekannter Weise elektrisch oder autogen überschweisst werden und ferner auf Gegenstände aus Bronze oder ähnlichen Legierungen vor der Veredelung auf die gleiche Art eine Hilfsschicht aus Nickel oder Kobalt oder deren Legierungen aufgebracht wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the partial material refinement of the surface of metal objects according to the parent patent No. 80064, characterized in that objects made of cast iron are electrically or autogenously welded in a known manner with an auxiliary layer of forgeable iron or steel or steel alloys before refining and furthermore onto objects made of bronze or Similar alloys, an auxiliary layer of nickel or cobalt or their alloys is applied in the same way before refining. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
