ABSTRACT:
A method for applying a highly porous alumina material that is useful in the hot section of a jet aircraft engine. In order to apply the porous alumina, an aluminum-based metal/alumina material known in the art is first placed onto an aircraft engine component substrate. The aluminum-based metal is then dissolved using a solution that will not affect the alumina or the underlying substrate. The alumina is then washed with deionized water and dried. The aircraft engine component may be first masked by applying a non-porous metal oxide material to the component or by oxidizing the surface of the component. The resulting alumina has a porosity in the range of about 20% to about 45%. The alumina has globular interconnected surface features in the range of about 0.5 μm to about 20 μm.
