Description
Verfahren zum Erzeugen eines für Bauteile und Geräte hoher Festigkeit geeigneten Werkstoffes n Zusatz zum Patent 895 698 Nach dem im Patente 895 6o8 beschriebenen Verfahren wird zum Erzeugen aiines bei hohen Temperaturen gute Festigkeitseiigensehaften aufweisenden Werkstoffes durch Sintern; und Reduzieren eines. Ausgangspulvergemisches ein Gemisch aus 75 bis 95 % Eisen und a5 b,iis 5 °/o Oxyden der Leichtmetalle oder schwerer als Eisenoxyd reduzierbarer Oxyde- verwendet und die Reduktion der zugesetzten Oxyde nur bis. zu einer sauerstoffärmeren Oxydationsstufe durchgeführt. Werkstoffe von bei hoher Temperatur noch größerer Festigkeit b iii gleichzeiitiig sehr, geringer Verschweißneigung werden. erhaltien, wenn erfindungsgemäß das im Ausgangspulvergemis ch vorhandene Oxyd durch ein Sulfid ersetzt wird. Auch in diesem Falle muß wie beim Verfahren nach dem Hauptpatent die Sinterung so. durchgeführt werden, daß das im Ausgangsgemiiisch vorhandene Sulfid in eine schwefelärmere Verbindung übergeführt wird, wobei unter schwefelärmerer Verbindung auch eine solche zu versitehen i.-st, hon der durch den Sintervorgang nur an: den Oberflächenschichten der Sulfidkörner eine Entfernung der Schwefelatome stattgefunden hat, wie dies besonders dann: eintriltt, wenn; das Ausgangsgemisch nicht in reduzierender Atmosphäre, also etwa in Wassersitoff, sondern im Vakuum gesintert wird.Method for producing a material suitable for components and devices with high strength n Addition to patent 895 698 According to the method described in patent 895 608, a material with good strength properties at high temperatures is produced by sintering; and reduce one. Starting powder mixture a mixture of 75 to 95% iron and a5 b, iis 5% oxides of light metals or oxides more difficult to reducible than iron oxide - used and the reduction of the added oxides only up to. carried out to a lower oxygen oxidation stage. Materials of even greater strength at high temperature b iii at the same time very, low tendency to weld. obtained when, according to the invention, the oxide present in the starting powder mixture is replaced by a sulfide. In this case too, as in the process according to the main patent, the sintering must be the same. be carried out that the sulfide present in the starting mixture is converted into a low-sulfur compound, with a low-sulfur compound also being provided, if the sintering process has only removed the sulfur atoms from the surface layers of the sulfide grains, such as this especially then: occurs when; the starting mixture is not sintered in a reducing atmosphere, for example in hydrogen, but in a vacuum.
Da Eisensulfid und auch die Sulfide der anderen Metalle der Eiisengruppe, nämlich Nickel-, Kobaltu und Mangansulfid, gegenüber Wasiserstoff wesentlich beständiger als Eisenoxyd sind, können in diesem Falle auch Eisensulfid, Nickelsulfid, Kobaltr sulfid und Mangansulfid als: Zusätze zu Eisenmetall verwendet werden. Außerdem sind aber auch die Sulfide der Leichtmetalle, dar zweiwertigen. Metalle, wie etwa Zink, Kupfer und Blei., sowie Mo,lybdänsulfid als Zusätze zu Eisenmetall besonders gut geeignet. Die gemäß dem Verfahren erzeugten Werkstoffe sind mit besonderem Vorteil für auf Reibung hochbeanspruchte Einrichtungen, wie Lager und Führungen schnell laufender Maschinen, aber auch überall dort verwendbar, wo, bei hohen Temperaturen verlangt wird.Since iron sulphide and also the sulphides of the other metals of the iron group, namely nickel, cobalt and manganese sulfide, much more resistant to hydrogen as iron oxide, iron sulfide, nickel sulfide, cobalt can also be used in this case Additives to ferrous metal are used as: sulfide and manganese sulfide. Also are but also the sulphides of light metals, which are divalent. Metals such as zinc, Copper and lead, as well as Mo, lybdenum sulfide as additives to ferrous metal are particularly good suitable. The materials produced according to the method are particularly advantageous for facilities subject to high friction, such as bearings and guides running machines, but can also be used anywhere, at high temperatures is required.
