COMPOSITE POWDERS SPRAYABLE TO FORM ABRADABLE SEAL COATINGS |
摘要 |
A composite powder sprayable by thermal spraying onto a substrate to form an abradable seal coating with suitable strength and erosion resistance. Each powder particle has a core of non-metallic solid material surrounded by a layer of metallic material selected from the group consisting of nickel and nickel alloys. At least about 95% of the particles have a size less than about 150 microns, at least about 50 to about 90% of the particles have a size greater than about 75 microns, and less than about 10% of the particles have a size less than about 45 microns. |
