Badania tribologiczne i biotribologiczne w Laboratorium Inżynierii Powierzchni i Tribologii Sieci Badawczej Łukasiewicz -- Instytutu Obróbki Plastycznej.

This paper presents the results of research, which are the effect of national and international projects carried out at the Łukasiewicz Research Network -- Metal Forming Institute, concerning both tribological and biotribological topics. The research results, the effect of which is the development of a new generation of forging tools (the design of cold forging tools with a properly prepared work surface and the development of new multilayered, nanostructured gradient coatings) and the solution to the problem of early wear of the parts working in difficult conditions are presented. For friction elements operating at high temperature, a solution has been developed that has found practical applications in the industry in the field of improving lubrication technology. The development of the technology of introducing solid lubricant particles onto the surfaces of tribologically cooperating parts operating at elevated temperatures has become extremely important for many industries that daily face problems with the early wear of cooperating elements. The second part of the work focuses on biotribological problems and the main challenge is to extend the durability of hip joint endoprostheses. In connection with this, work was carried out to thoroughly understand the process of endoprosthesis wear. Examination of the tribological properties of new materials intended for elements of endoprostheses is also a very important issue. The research was conducted on a specially designed and built hip joint simulator, which meets the requirements of the ISO standard. [ABSTRACT FROM AUTHOR]
