Determination of the friction coefficient of metal alloys used in dentistry as a reference to the wear of materials

Written by Markovics Emese, Bocskay István

Casted metal alloys are widely used for fixed prosthetic restorations in dentistry. Their physical and chemical properties determine the materials’ behavior in their ambience, in our case the oral cavity. In this study we tried to examine some differences of physical properties (like hardness, friction coefficient reported to a standard alloy), depending on the materials’ microstructure. We used the Vickers test method to appreciate the hardness of alloys, and the Falex type wear test machine for the measurement of friction coefficient. Our results highlight how the microstructural differences of the analyzed alloys can determine variations in deliberate properties.
