Plasma Sprayed Ceramic Thermal Barrier Coating For Nial-Based Intermetallic Alloys

View page
US Patent:
53024656, Apr 12, 1994
Filed:
Oct 26, 1992
Appl. No.:
7/970669
Inventors:
Robert A. Miller - Brecksville OH
Joseph Doychak - Westlake OH
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
B22F 700
US Classification:
428552
Abstract:
A thermal barrier coating system consists of two layers of a zirconia-yttria ceramic. The first layer is applied by low pressure plasma spraying. The second layer is applied by conventional atmospheric pressure plasma spraying. This facilitates the attachment of a durable thermally insulating ceramic coating directly t the surface of a highly oxidation resistant NiAl-based intermetallic alloy after the alloy has been preoxidized to promote the formation of a desirable Al. sub. 2 O. sub. 3 scale.

Consecutive Plate Acoustic Suppressor Apparatus And Methods

View page
US Patent:
52507645, Oct 5, 1993
Filed:
Oct 16, 1992
Appl. No.:
7/961943
Inventors:
Joseph Doychak - Westlake OH
Tony L. Parrott - Williamsburg VA
Assignee:
The United States of America as represented by the Administrator of the
National Aeroneutics and Space Administration - Washington DC
International Classification:
E04F 1704
US Classification:
181224
Abstract:
An apparatus and method for suppressing acoustic noise utilizes consecutive plates, closely spaced to each other so as to exploit dissipation associated with sound propagation in narrow channels to optimize the acoustic resistance at a liner surface. The closely spaced plates can be utilized as high temperature structural materials for jet engines by constructing the plates from composite materials. Geometries of the plates, such as plate depth, shape, thickness, inter-plate spacing, arrangement, etc. , can be selected to achieve bulk material-like behavior.
