Surface composition of the Co-Cr based alloys after different lab denture treatments using auger electron spectroscopy




surface treatment, Co-Cr based dental alloys, Auger Electron Spectroscopy, artificial saliva


The aim of this work is analysis of dental Co-Cr-based alloy surface chemical composition after several technological procedures adopted in the dental practice using Auger Electron Spectroscopy (AES). This analysis was performed after casting the alloy samples were subjected to the following sequential treatments: cutting on by the diamond wheel, electric-spark cutting and grinding, electropolishing, exposure in artificial saliva after 2 days after electropolishing
