4. Alliage selon l'une des revendications 1 à 3, sous la forme d'une poudre pour la projection thermique.
5. Electrode de soudure pour la formation d'un dépôt constitué d'un alliage selon l'une des revendications précitées, caractérisée en ce qu'elle contient, dans son ensemble, les éléments énumérés dans l'une des revendications 1, 2 ou 3 dans les proportions indiquées dans ces revendications, soit sous forme élémentaire, soit sous forme d'alliage ou de préalliage.
6. Electrode selon la revendication 5, caractérisée en ce qu'elle se présente sous la forme d'une électrode enrobée ou d'une électrode en forme de tube ou fil fourré.
7. Outil de coupe, de transformation ou de guidage constitué au moins en partie d'un alliage selon l'une des revendications 1 à 3.
La présente invention concerne un alliage résistant à l'usure pouvant notamment constituer tout ou partie d'un outil de coupe, de transformation ou de guidage, une couche de protection ou une partie renforcée d'une pièce, sinon la pièce entière.
Il existe déjà des alliages spéciaux résistant à l'usure, en particulier des alliages à base de cobalt tels que l'alliage Stellite 6.
L'invention vise à fournir un alliage à grande résistance à l'usure et dont la teneur en cobalt, métal relativement rare, ne dépasse pas 30% en poids de l'alliage.
L'alliage selon l'invention contient, en pour-cent en poids, jus qu'à 0,3% de C, 10 à 30% de Cr, jusqu'à 4% de Ni, 10 à 30% de
Co, jusqu'à 5% de Mn, jusqu'à 3% de Si, jusqu'à 10% de Mo, jus qu'à 5% de W, le reste étant du fer.
Des résultats particulièrement avantageux ont été atteints avec un alliage contenant, en pour-cent en poids, jusqu'à 0,2% et de pré férence jusqu'à 0,1% de C, 12 à 25% et de préférence 15 à 20% de
Cr, jusqu'à 1% et de préférence jusqu'à 0,6% de Ni, 10 à 20% et de préférence 12 à 16% de Co, jusqu'à 2% et de préférence jusqu'à 1% de Mn, jusqu'à 1,5% et de préférence jusqu'à 1,2% de Si, jusqu'à 5% et de préférence jusqu'à 3% de Mo, jusqu'à3% et de préférence jusqu'à 2% de W, le reste étant du fer.
Cet alliage peut servir à la fabrication d'outils tels que des outils de coupe ou des outils pour la mise en forme de pièces sans copeaux comme pliage ou étirage. L'alliage peut également servir à la fabrication de rouleaux de coulée continue, de pièces soumises à la chaleur ou à la corrosion telles que vannes, clapets, etc. De préférence, pour des raisons économiques, on recouvre de cet alliage seulement les surfaces soumises à l'usure. Cela peut se faire par un procédé de soudage tel que TIG ou MIG, la préférence étant souvent donnée à des procédés utilisant des électrodes enrobées, des électrodes continues ou des poudres.
L'invention a également pour objet une électrode de soudure pour la formation d'un dépôt constituée par l'alliage selon l'invention, cette électrode contenant dans son ensemble les éléments de l'alliage dans les proportions indiquées, et cela soit sous forme élémentaire, soit sous forme d'alliage ou de préalliage.
L'alliage selon l'invention peut également constituer une poudre de projection thermique permettant de réaliser, par exemple au moyen d'une installation de projection à plasma ou à flamme chimique, un revêtement de protection contre l'usure.
Exemple
On a réalisé, au moyen d'un procédé de soudage utilisant une électrode, un dépôt comprenant 0,04% de C, 17% de Cr, 0,3% de
Ni, 14,1% de Co, 0,2% de Mn, 1,05% de Si, 2,1% de Mo, 0,5% de
W, reste fer. L'alliage ainsi obtenu s'est révélé présenter une résistance à l'usure meilleure que celle des alliages à base de cobalt utilisés précédemment et a permis de prolonger nettement la durée de service de l'outil formé.

4. Alloy according to one of claims 1 to 3, in the form of a powder for thermal spraying.
5. Welding electrode for the formation of a deposit made of an alloy according to one of the aforementioned claims, characterized in that it contains, as a whole, the elements listed in one of claims 1, 2 or 3 in the proportions indicated in these claims, either in elementary form or in the form of an alloy or a pre-alloy.
6. An electrode according to claim 5, characterized in that it is in the form of a coated electrode or an electrode in the form of a tube or cored wire.
7. Cutting, processing or guiding tool consisting at least in part of an alloy according to one of claims 1 to 3.
The present invention relates to a wear-resistant alloy which can in particular constitute all or part of a cutting, transforming or guiding tool, a protective layer or a reinforced part of a part, if not the whole part.
There are already special wear-resistant alloys, in particular cobalt-based alloys such as the Stellite 6 alloy.
The invention aims to provide an alloy with high wear resistance and whose content of cobalt, a relatively rare metal, does not exceed 30% by weight of the alloy.
The alloy according to the invention contains, in weight percent, up to 0.3% of C, 10 to 30% of Cr, up to 4% of Ni, 10 to 30% of
Co, up to 5% Mn, up to 3% Si, up to 10% Mo, up to 5% W, the rest being iron.
Particularly advantageous results have been achieved with an alloy containing, in weight percent, up to 0.2% and preferably up to 0.1% C, 12 to 25% and preferably 15 to 20 % of
Cr, up to 1% and preferably up to 0.6% of Ni, 10 to 20% and preferably 12 to 16% of Co, up to 2% and preferably up to 1% of Mn, up to 1.5% and preferably up to 1.2% Si, up to 5% and preferably up to 3% Mo, up to 3% and preferably up to 2% W , the rest being iron.
This alloy can be used to manufacture tools such as cutting tools or tools for shaping parts without shavings such as bending or drawing. The alloy can also be used to manufacture continuous casting rollers, parts subjected to heat or corrosion such as valves, valves, etc. Preferably, for economic reasons, only the surfaces subjected to wear are covered with this alloy. This can be done by a welding process such as TIG or MIG, preference is often given to processes using coated electrodes, continuous electrodes or powders.
The invention also relates to a welding electrode for the formation of a deposit formed by the alloy according to the invention, this electrode as a whole containing the elements of the alloy in the indicated proportions, and this is in the form elementary, either in the form of an alloy or a pre-alloy.
The alloy according to the invention can also constitute a thermal spraying powder making it possible, for example by means of a plasma or chemical flame spraying installation, to provide a protective coating against wear.
Example
Was carried out, by means of a welding process using an electrode, a deposit comprising 0.04% of C, 17% of Cr, 0.3% of
Ni, 14.1% Co, 0.2% Mn, 1.05% Si, 2.1% Mo, 0.5%
W, stay iron. The alloy thus obtained was found to have a better wear resistance than that of the cobalt-based alloys used previously and made it possible to significantly extend the service life of the tool formed.
