The paper presents the results of tests of tribological wear of two Co-Cr-Mo alloys (Wironit LA) and Co-Cr-Mo-W (Colado CC) used to make skeletal prostheses, combined works, implants and metal frameworks for ceramics. The test samples were centrifugally cast using the lost wax method and subjected to hardness measurements, microscopic observations, and a quantitative description of the microstructure. SEM examinations and EDS analysis of micro-areas on dendritic arms and interdendritic areas were performed together. The abrasive wear resistance tests with the use of a T-05 tester in the friction system roller-block were conducted in a dry sliding contact under the conditions of a metal-metal contact with the load of 100 N and for two friction paths, 500 and 1000 m.

W pracy przedstawiono wyniki badań zużycia tribologicznego dwóch stopów Co-Cr-Mo (Wironit LA) i Co-Cr-Mo-W (Colado CC) stosowanych do wykonywania protez szkieletowych, prac kombinowanych, implantów i szkieletów metalowych pod ceramikę. Badane próbki odlewano odśrodkowo metodą wosku traconego i poddawano pomiarom twardości, obserwacjom mikroskopowym wraz z ilościowym opisem mikrostruktury. Wykonano badania SEM wraz z analizą EDS mikroobszarów na ramionach dendrytycznych oraz obszarów interdendrytycznych. Badania odporności na zużycie ścierne z wykorzystaniem testera T-05 w układzie ciernym wałek–blok przeprowadzono w suchym styku ślizgowym w warunkach kontaktu metal–metal z obciążeniem 100 N i dla dwóch dróg tarcia, 500 i 1000 m.
