Phase Changes in Base Metal Alloys Along Metal-porcelain Interfaces
George R. Baran
Department of Operative Dentistry, Temple University, Philadelphia, Pennsylvania 19140
Five commercial, base metal alloys used with porcelain were investigated. After oxidizing heat treatments and the porcelain bake, phase changes occurred in some alloys near the porcelain interface. These changes were due to the depletion of the matrix in alloying elements as a result of the oxidizing treatments.
