Abstract

1456554 Sintered high temperature metal oxide seal UNITED AIRCRAFT CORP 23 Jan 1974 [28 March 1973] 03206/74 Headings C7A and D A homogeneous and porous abradable seal material of structure consisting principally of B and J phases consists of:- The material may be produced by blending a powder mixture of:- Mixing with cellulose nitrate binder, packing into a holding member (e.g. stainless steel, nickel or Ni-Co base alloy) coated with a brazing alloy and cellulose nitrate binder, evaporating the binder and liquid phase sintering in argon at 982‹C for 4 hours, 1066‹C for 2 hours, and 1107‹C for one hour than heating the sintered mixture in air at 982‹C to produce a protective oxide layer of Al 2 O 3 , Co Al 2 O 4 and Ni Al 2 O 4 . The abrasive seal material so formed may comprise 35-65% porosity and may be used as a rotor seal in gas turbine engines.
