Description

Hochverschleißfeste Teile, insbesondere für Misch- und MahlaggregateHighly wear-resistant parts, especially for mixing and grinding units

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung bezieht sich auf Keramikindustrie, Metallurgie und Maschinenbau. Objekte, in denen ihre Anwendung möglich und zweckmäßig ist, sind verschleißfeste Teile in Maschinen und Vorrichtungen, insbesondere Misch- und Mahlaggregate. Die Anwendung kann auch unter korrosiven Bedingungen erfolgen.The invention relates to the ceramic industry, metallurgy and mechanical engineering. Objects in which their application is possible and expedient are wear-resistant parts in machines and devices, in particular mixing and grinding units. The application can also be carried out under corrosive conditions.

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

Bekannt sind Mahlkörper und Mahltrommeln aus Hartmetall, Stahl, Porzellan, Plintsteinen, Achat, Plasten und Titanmetall. Sie gewährleisten durch ihren Abrieb keine verunreinigungsarme Aufbereitung des Mahlgutes, besitzen nur eine geringe Mahlwirkung und/oder sind durch aufwendige Herstellung teuer.Known grinding media and grinding drums made of carbide, steel, porcelain, Plintsteinen, agate, plastics and titanium metal. They ensure by their abrasion no low-contamination treatment of the ground material, have only a small grinding action and / or are expensive to manufacture.

Weiterhin sind bereits Mahlkugeln aus einem Werkstoff auf der Basis von Titan und Sauerstoff aus bis zu 97 Gew.-% Tit>2 und einem als Plastifikator und Bindemittel wirkenden Stoff, beispielsweise Bentonit oder Zelluloseäther, bekannt (A. Palatzky, Techn. Keramik, VSB Verlag Technik, Berlin 1954). Dieser Werkstoff hat den Mangel, daß wegen der geringen Abriebfestigkeit die daraus hergestellten Teile häufig ausgewechselt werden müssen und Zumahlungen zum Mahlgut die Verarbeitbarkeit des Mahlgutes und dieFurthermore, grinding balls made from a material based on titanium and oxygen of up to 97% by weight of titanium> 2 and a substance acting as plasticizer and binder, for example bentonite or cellulose ethers, are already known (A. Palatzky, Techn. Keramik, VSB Verlag Technik, Berlin 1954). This material has the defect that because of the low abrasion resistance, the parts produced therefrom must be replaced frequently and Zumahlungen the regrind the processability of the ground material and the

Gebrauchseigenschaften der aus dem Mahlgut hergestellten Gegenstände erheblich herabsetzen. Mahlkörper aus dem genannten Werkstoff bedingen durch ihre relativ geringe Dichte von etwa 4 gem" ^ eine relativ lange Mahldauer. Durch Zusatz von Bleiverbindungen in Höhe von 2 bis 1ü Gewichtsprozent zu gepulvertem TiOg ist es gelungen, die Abriebfestigkeit derartiger Mahlkugeln fast zu verdoppeln (DE-PS 1 07.2 179) ί der Verschleiß ist aber immer noch relativ hoch und das Auftauchen von Blei in der Zumahlung bringt weitere Probleme.Significantly reduce the performance characteristics of the objects produced from the regrind. Due to their relatively low density of about 4 μm, grinding bodies made of the mentioned material require a relatively long grinding time. By adding lead compounds in the amount of 2 to 1% by weight to powdered TiO 2 it has been possible to almost double the abrasion resistance of such grinding balls (DE). PS 1 07.2 179) ί the wear is still relatively high and the emergence of lead in the payment brings further problems.

Ziel der ErfindungObject of the invention

Ziel der Erfindung ist die Verlängerung der Einsatzdauer verschleißbeanspruchter Teile sowie die weitgehende Vermeidung schädlicher Zumahlungen und Herabsetzung der Mahldauer bei Mahlprozessen in der Keramikindustrie und Metallurgie .The aim of the invention is to extend the period of use of wear-stressed parts and to a large extent avoid harmful adulteration and reduce the grinding time in milling processes in the ceramics industry and metallurgy.

Darlegung des Wesens der ErfindungExplanation of the essence of the invention

Der Erfindung liegt die Aufgabe zugrunde, Teile mit Oberflächen hoher Abriebfestigkeit unter Beibehaltung der Eigenschaften des Grundkörpers anzugeben. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Teile aus einem Grundkörper, versehen mit einer Oberflächenschicht aus Titan oder einer Ti-3asis-Legierung, bestehen, die mit 0,5 - 15 Atomprozent Sauerstoff und 0,03 - 7,5 Atomprozent Stickstoff in gelöster Form legiert ist. Zweckmäßig ist ein Gehalt von 2-10 Atomprozent Sauerstoff und 1-6 Atomprozent Stickstoff, günstig ein Verhältnis zwischen Sauerstoff und Stickstoff von 2 : 1. Es kann zweckmäßig sein, nicht die gesamte Oberfläche, sondern nur hochbeanspruchte Stellen davon zu legieren. Der Grundkörper, der die erfindungsgemäß zusammengesetzte Schicht trägt, bleibt als Schichtträger in seinen Eigenschaften unbeeinflußt. Zweckmäßigerweise kann der Grundkörper auch aus Titan oder einer Titan-Basis-Legierung bestehen.The invention has for its object to provide parts with surfaces high abrasion resistance while maintaining the properties of the body. According to the invention the object is achieved in that the parts of a body provided with a surface layer of titanium or a Ti-3asis alloy, consisting of 0.5 to 15 atomic percent oxygen and 0.03 to 7.5 atomic percent nitrogen in dissolved form is alloyed. Suitably, a content of 2-10 atomic percent oxygen and 1-6 atomic percent nitrogen, favorably a ratio between oxygen and nitrogen of 2: 1 It may be appropriate not to alloy the entire surface, but only highly stressed sites thereof. The base body which carries the composite layer according to the invention remains unaffected as a substrate in its properties. Appropriately, the base body may also consist of titanium or a titanium-based alloy.

Ausführungsbeispielembodiment

Als hochverschleißfester Werkstoff für zylindrische Mahlkörper dient Titan mit 6 Atomprozent gelöstem Sauerstoff und 3 Atomprozent gelöstem Stickstoff. Gegenüber bekannten Mahlkörpern auf der Basis von TiOp verlängert sich die Einsatzdauer um das 20-fache und die erforderliche Mahldauer verkürzt sich um etwa 20 %, Gegenüber Kugeln aus Achat wird bei gleicher Verschleißfestigkeit eine Verkürzung der Mahldauer um das 5- bis 8-fache erzielt und der Preis ist erheblich niedriger.As a highly wear-resistant material for cylindrical grinding media titanium is used with 6 atomic percent dissolved oxygen and 3 atomic percent dissolved nitrogen. Compared to known grinding bodies based on TiOp, the service life is increased by 20 times and the required grinding time is reduced by about 20 %, compared to spheres of agate with the same wear resistance shortening the milling time by 5 to 8 times achieved and the price is considerably lower.
