THE INFLUENCE OF CURRENT DENSITY IN THE ELECTROPOLISHING PROCESS AT THE STEREOMETRIC SURFACE PROPERTIES OF THE Co-Cr DENTAL ALLOYS

摘要

Preparatory procedures, technology melting / casting and final treatment have a significant impact on the stereochemistry of the metal surface of prosthetic design. The study investigated the dependence of the rate of dissolution of metallic prosthetic structures subjected to the process electropolishing a function of current density (A/cm(2)). The study used Collado CC dental alloy and Magnum H75 alloy. It was found that the development of the surface of the material promotes its destruction, and the electropolishing process, over a range of technological parameters prevents this by surface smoothing.
