Selected Properties And Tribological Wear Alloys Co-Cr-Mo And Co-Cr-Mo-W Used In Dental Prosthetics

Abstract

The presented work provides the results of the abrasive wear resistance tests performed on Co-Cr-Mo and Co-Cr-Mo-W alloys with the use of the Miller’s apparatus. The analyzed alloys underwent microstructure observations as well as hardness measurements, and the abraded surfaces of the examined materials were observed by means of electron scanning microscopy. The performed examinations made it possible to state that the Co-Cr alloys characterized in a high hardness, whereas the changes in the mass decrement were minimal, which proved a high abrasive wear resistance.

THE EFFECT OF HEAT TREATMENT ON THE MICROSTRUCTURE AND PROPERTIES OF THE CORROSION RESISTANCE OF THE PROSTHETIC ALLOY WIRONIT EXTRAHART (Co-Cr-Mo)

“…Co-Cr-Mo alloys, belonging to the group of biomaterials, are extensively applied in prosthetics and stomatology, owing to their desired mechanical properties, high corrosion resistance and good biotolerance in the environment of tissues and body fluids [1]. The microstructure and properties of Co-Cr-Mo alloys are largely dependent on the technique of their production [2]. Prosthetic elements are usually produced through casting [1,3] due to the complexity of the shapes and the necessity of adjusting the element to the anatomy of the patient.…”

“…All of the properties of a material are inherently related with its chemical composition and structure. Meanwhile the structure of a material is dependent on the type of manufacturing technology [1][2][3][4][5][6][7][8]. Currently, modern CAD/CAM systems based on 3D printing are increasingly used in dental applications and thus they become alternatives to the traditional method of casting.…”
