CA 2216068

Thermally sprayable powders for the formation of abradable seals, and abradable seals formed by thermally spraying the powders, suitable for use with Ti alloy blades at temperatures up to 700°C are disclosed. The powder includes an alloyed metal phase material and a solid lubricant type ceramic phase material. The alloyed metal phase material includes a major amount of at least one matrix metals selected from the group consisting of Ag and Cu, at least one melting point depressing metal selected from the group consisting of Si, B, Mn, and Al, and at least one oxidation resistant metal selected from the group consisting of Al, Cr, and Si. The solid lubricant-type ceramic phase material is preferably selected from hexagonal boron nitride, molybdenum sulphide, graphite, talc, bentonite or mica.

Poudres thermopulvérisables pour la formation de joints abradables; joints ainsi formés, utiles pour des éléments en alliage au titane, à des températures allant jusqu'à 700 degrés C. La poudre comprend une matière dans une phase métallique alliée et une matière dans une phase céramique de type lubrifiant. La matière dans la phase métallique alliée renferme une importante quantité d'au moins un métal matriciel, choisi parmi Ag et Cu, au moins un métal abaissant le point de fusion, choisi parmi Si, B, Mn et Al, et au moins un métal résistant à l'oxydation, choisi parmi Al, Cr et Si. La matière dans la phase céramique de type lubrifiant est choisie de préférence parmi le nitrure de bore hexagonal, le sulfure de molybdène, le graphite, le talc, la bentonite ou le mica.
