Purpose: The aim of this work was to define the influence of manufacturing technology on the chemical composition, surface topography, physicochemical and electrochemical properties of CoCr alloys obtained by casting technology and Direct Metal Laser Sintering. Design/methodology/approach: This work presents microstructural and chemical compositions obtained by scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDS). Additionally, corrosion pitting analysis and roughness measurement were conducted on the samples. Findings: On the basis of the investigations, it can be stated that the prosthetic restorations are different depending on the type manufacturing technology. Based on the obtained results it was found that the structures of both materials are chemically inhomogeneous. The investigated alloy exhibited similar polarization curve character. Practical implications: The rapid prototyping methods are a new technology used for getting details e.g. by CAD/CAM procedure. Using Direct Metal Laser Sintering (DMLS) method can simplify the technology of producing prosthetics restrictions and is an alternate way for standard casting technology. Originality/value: The paper presents comparative research of two Co-Cr alloys, from which the samples were obtained in conventional casting and DMLS technology.
