Purpose: of this paper is to discuss a division of the surgical tools according to the different criteria and to indicate the dominant wear processes of the medical tools. Moreover, the paper gives some guidelines on improvement in wear resistance of the medical tools by the surface treatment. Design/methodology/approach: Objectives were achieved thanks to the frictional and wear tests carried out on the T05 test stand ("ring-block" tester). An influence of the different surface treatments carried out for Ti6Al4V titanium alloy on its wear resistance was examined. Moreover, "scratch test" was done. Findings: In the course of the work it was found that the application of nitrogen titanizing process can increase wear resistance of the titanium alloys several times. This can expand the application range of titanium alloys for elements, which are subjected to intensive wear. Research limitations/implications: Wear tests belong to the long-lasting tests, so it is the main research limitation. Practical implications: Surface treatment discussed in the paper is partially used for production of the titanium medical tools (some kinds of forceps). An application of the titanium surgical tools is advisable because of their high mechanical strength and low weight. Originality/value: A part of the tests was carried out for the frictional pair: "titanium alloy+surfacing - animal bone". Such tests allow for better determination of the wear resistance occurring during surgical operations, i.e. during the direct contact between the surgical tool and bone tissue.
