Purpose: Presented researches aimed at evaluating the structure and corrosion properties of CoCr-base elements fabricated by means of soft material milling with later sinterization in a protective atmosphere in comparison to casted alloy. Design/methodology/approach: CoCr-base samples were fabricated by soft material milling followed by sinterization in neutral gas environment and casted by traditional casting techniques. EDS-SEM study was used to evaluate the microstructure and quantitative analysis of chemical composition. Corrosion resistance evaluation was based on examining corrosion parameters (Ecorr, jcorr, Rpol), corrosion behaviour of both kind of samples was also studied by using open circuit potential v/s time measurements to assess the protective nature of the applied manufacturing methods and by potentiodynamic polarisation technique. Findings: Differences in structure were found, sintered material was more homogenous in comparison to dendritic structure of the cast alloy. Corrosion parameters (corrosion potential - Ecorr, corrosion current density - jcorr, polarization resistance Rp , open circuit potential versus time - OCP) indicate higher corrosion resistance of sintered element. Course of the polarization curve proves, that the sintered alloy exhibits better self-passivating properties in comparison to casted material. Research limitations/implications: The research was carried out on samples, not on final restoration elements. As the technology based on soft CoCr-base alloy milling followed by sinterization in neutral gas environment has been developed last years, additional investigations are needed to obtain more precise results in corrosion properties evaluation. Originality/value: PM technology based on soft material milling with later sintering in a protective atmosphere is the new technology used for fabrication of metal prosthodontic dentures. This method seems to be promissing alternative to laser micro-sintering, and makes it possible to achieve a product with a far more homogenous structure in comparison to traditional casting and does not require as expensive instrumentation necessary for the SLM method. It is crucial to examine in details the corrosion resistance of elements obtained by this new technology.
