Title: Method and apparatus for production of graded ceramic-metal microstructures

Patent Application ·
OSTI ID:140605

A method and apparatus that produces a graded microcomposite is disclosed that controls the residual stresses developed at dissimilar material interfaces due to differences in material properties. The feasibility of fabricating graded Al{sub 2}O{sub 3}-metal materials by two techniques, physical vapor deposition and powder metallurgy, is demonstrated. Results from microstructural characterization of these materials are presented.
