Abstract
Ni-Cr-Mo alloys have been widely used as fixed dental prostheses and in this work different remelting behaviors which can change mechanical proprieties and corrosion resistance are used. This work aim is to analyze the electrochemical behavior, microstructures and two alloys hardness remelted through remelting process in open flame (oxyacetylene torch) and through induction in high frequency furnace. Superficial analysis for optical microscopy has revealed dendrite structures with wide and precipitate grains in their boundaries. Alloys recast by induction present larger hardness values.
