-22- Porous Metal Abradable Seal Material Abstract Porous metal structures are especially useful as abradable seals in axial flow compressors. Care- fully defined oxide content and density provide a superior combination of abradability and particulate erosion resistance. The seals are comprised of 1-30 weight percent oxide and have 27-38 percent of the solid metal density. A preferred seal is made by plasma arc spraying a mixture of 80Ni-20Cr and polymethylmethacrylate powders and then heating the resultant deposit in air to about 315°C to cause the polymer to flee. The nichrome seal will have less than 15 percent oxide and a density of about 2.7 g/cm3, about 32 percent of the solid metal density.
