Abstract

The components are made of Ti contg. (atomic %) 0.5-15(2-10)% dissolved oxygen, and 0.03-7.5 (1-6)% dissolved nitrogen. The ratio of oxygen:nitrogen in the components is pref. 2:1; and a Ti alloy may be used instead of Ti. The components are used esp. as milling- balls or -rollers in the ceramics- or metal-industries, or in machine construction; and also resist corrosive environments. The components are very easy to mfr. and possess a very high resistance to abrasion and wear.

Description

L'invention concerne des pièces ayant une résistance élevée à l'usure, pour machines et dispositifs, en particulier pour des mélangeurs et des broyeurs dans lesquels leur application est possible et utile. les domaines d'application de l'invention sont l'industrie de la céramique, la métallurgie et la construction mécanique. L'application de l'invention peut également avoir lieu en milieu corrosif. The invention relates to parts having a high wear resistance, for machines and devices, in particular for mixers and mills in which their application is possible and useful. the fields of application of the invention are the ceramic industry, metallurgy and mechanical construction. The application of the invention can also take place in a corrosive medium.

On connaît des éléments broyeurs et des tambours de broyage en métal dur, acier, porcelaine, silex, agate, matière plastique et titane. En raison de leur usure, ils n'assurent pas un traitement exempt de pollution des matières à broyer, ne présentent qu'une faible capacité de broyage, et/ou leur mode de préparation les rend coûteux. Grinding elements and grinding drums are known in hard metal, steel, porcelain, flint, agate, plastic and titanium. Due to their wear, they do not provide a pollution-free treatment of the materials to be ground, have only a low grinding capacity, and / or their method of preparation makes them expensive.

On connaît également des billes de broyeur en un matériau à base de titane et oxygène, soit jusqu'à 97 % en poids de TiO2 et une matière jouant le rôle de plastifiant et de liant, par exemple des bentonites ou de l'éther de cellulose (A. Palatzky, Techn. Eeramik, VEB Verlage Technique, Berlin, 1954). There are also known grinder balls made of a material based on titanium and oxygen, that is to say up to 97% by weight of TiO2 and a material playing the role of plasticizer and binder, for example bentonites or cellulose ether. (A. Palatzky, Techn. Eeramik, VEB Verlage Technique, Berlin, 1954).

le défaut de ce zen matériau, ctest qu'en raison de sa faible résis- tance à l'usure, les pièces que l'on en fabrique doivent être souvent échangées et le supplément de broyage abaisse considérablement l'aptitude à l'usinage du matériau broyé, et restreint le domaine d'application des objets qui en sont fabriqués. Les éléments broyeurs constitués par le matériau mentionné, imposent en raison de leur densité relativement faible de 4g/cm3, une durée de broyage relativement élevée. Par addition de composés du plomb en proportions allant de 2 à 10 ffi en poids, au TiO2 en poudre, on a réussi à doubler pratiquement la résistance à l'abrasion de billes de broyage de ce type (DE PS 1 072 179) mais l'usure reste encore relativement élevée, et le passage du plomb dans la matière broyée pose d'autres problèmes. the defect of this zen material is that due to its low resistance to wear, the parts which are manufactured from it must be often replaced and the grinding supplement considerably lowers the machinability of the crushed material, and restricts the field of application of the objects produced from it. Due to their relatively low density of 4g / cm3, the grinding elements made up of the mentioned material require a relatively high grinding time. By adding lead compounds in proportions ranging from 2 to 10 ffi by weight, to powdered TiO2, it has been possible to practically double the abrasion resistance of grinding balls of this type (DE PS 1 072 179) but l wear is still relatively high, and the passage of lead into the ground material poses other problems.

l'invention a pour objectif de prolonger la durée d'action de pièces soumises à l'usure, ainsi que 11 élimination dans une grande mesure des suppléments de broyage nuisibles? et l'abaissement de la durée de broyage dans l'industrie de la céramique et la métallurgie. the object of the invention is to extend the duration of action of parts subject to wear, as well as the elimination to a large extent of harmful grinding supplements? and lowering the grinding time in the ceramic industry and metallurgy.

L'invention s'est fixée pour but de proposer des éléments hautement résistants à l'usure, avec une meilleure tenue à l'abrasion, une densité relativement élevée, et un faible court de production. The invention has set itself the aim of providing elements which are highly resistant to wear, with better abrasion resistance, a relatively high density, and a short production run.

A cet effet, l'invention propose des éléments constitués de titane, avec 0,5 à 15 k atomique d'oxygène dissous et 0,03 à 7,5 % atomique d'azote dissous. Des teneurs en oxygène de 2 à 10 % atomique, et en azote de 1 à 6 fiv atomique, sont recommandées.Unrapport de l'oxygène à l'azote de 2 pour 1 est favorable. A la place de titane on peut également utiliser, pour des applications déterminées, des alliages de titane. To this end, the invention provides elements made of titanium, with 0.5 to 15 atomic k of dissolved oxygen and 0.03 to 7.5 atomic% of dissolved nitrogen. Oxygen levels of 2 to 10 atomic% and nitrogen of 1 to 6 atomic fiv are recommended. A ratio of oxygen to nitrogen of 2 to 1 is favorable. Instead of titanium, titanium alloys can also be used for specific applications.

Comme matériau hautement résistant à l'usure pour éléments broyeurs cylindriques, on prend du titane avec 6 % atomique d'oxygène dissous et 3 % atomique d'azote dissous. Comparée8 à des éléments broyeurs connus, à base de Ti02, la durée d'action des éléments proposés est 20 fois plus longue, et la période de broyage nécessaire est raccourcie de 20. Par rapport à des billes en agate, pour une même résistance à l'usure, on obtient une période de brcyage de 5 à 6 plus courte, et le cott en est nettement plus faible.  As highly wear-resistant material for cylindrical grinding elements, titanium is used with 6 atomic% of dissolved oxygen and 3 atomic% of dissolved nitrogen. Compared8 to known grinding elements, based on TiO 2, the duration of action of the proposed elements is 20 times longer, and the grinding period required is shortened by 20. Compared to agate balls, for the same resistance to wear, we obtain a shorter brciation period of 5 to 6, and the cost is much lower.
