The parameters for conventional powder-metallurgical production of a CoCrMo alloy for dental implants were determined. With the application of these parameters an alloy with sufficient green density, low porosity after sintering, considerable hardness and spontaneously passive behavior in the Ringer solution can be achieved. The comparison of samples with different sintering temperatures revealed that a slight variation of the sintering temperature can have a considerable effect on the physical, mechanical and electrochemical properties of the alloy.
