Abstract: Objective:To investigate the effect of porcelain bake cycles on oxide layer form ed on cobalt-chromium alloy surface.Methods:Fixed spot analysis of EPMA methods was adopted to measure the oxygen at o mic percentage inward from the edge of cross-section interface of alloy pieces. The adherent state of oxide layer on the surface of substrate alloy was observed .Results:The oxide layer on the surface of alloy had stable thickness and contain ed more and more oxide as porcelain firing times increased.In some area,oxide la yer fractured from the substrate metal.Conclusion:Cobalt-chromium alloy frame should be abrased and polished thoroughl y after porcelain bake cycles.
