Experimental Researches of Co-Cr Alloys Powders Manufactured by Sintering Process DMLS and Ni-Cr Alloys Used in Dentistry

The purpose of this study was to evaluate the chemical and metallurgical aspects, mechanical properties and hardness of the Co-Cr alloy powders manufactured by sintering process DMLS and compared with Ni-Cr alloys used for personalized dental crowns.In dentistry are develop new methods to obtain personalized dental crowns quickly, the cost is not expensive and is identically with the dental scan realized by dentist. DMLS sintering manufacturing is a new method who permits to realize in the same day the dental crowns with the first control.Powders of Co-Cr alloys presents good sintered properties, good mechanical properties and the sintered probes don’t present tensile strength in the material after DMLS process.
