Abstract

A method for whisker formation on the surface of aluminum containing metallic 5 alloy fibers and substrates provides a support structure for many technical, medical and pharmaceutical applications. The novel surface modification of metallic alloy fibers and other metallic substrates involves heating the fiber or substrate in air at temperatures ranging from approximately 800°C to approximately 1000°C for a period of time ranging from approximately 10 hours to approximately 100 hours to form whiskers. The use of a 10 metal oxide coating with large ions, such as zirconium oxide, allows the formation of alumina whiskers while preserving the structural integrity of the metallic alloy substrate. Uses of the present invention include, but are not limited to an advanced catalyst support, a highly efficient filter medium, a support for implants and the like.
