Comparative study on the corrosion of alloys in artificial saliva
Romanian Journal of Stomatology, 2018 Four types of dental alloys used in metal-ceramic technology, two NiCr-based and two CoCr-based, were studied for corrosion resistance. Of the 4 types of alloys, circular samples of 14 mm in diameter and 4 mm thickness were poured into the dental laboratory which were subsequently processed and subjected to corrosion in artificial saliva at the ...
