Opis:: Grinding is still an important method for surface finishing. At FPTM JEPU research, which deals with this issue is conducted. Experiments are carried out with grinding various materials under different conditions and then selected components of the surface integrity are evaluated. They include roughness Ra, Rm and Rz, Material ratio curve (Abbott Firestone curve) and also the obtained roundness. This article deals with grinding nickel Inconel 718 alloy, when selected cutting grinding conditions were used and subsequently the surface profile and the material ratio curve were measured and evaluated.

Opis:: The paper presents an analysis of the surface layer of Fe-Mn-C-B-Si-Ni-Cr alloy coating after friction with C45 steel. The coatings were obtained by arc welding (GMA). Flux-cored wires were used as a welding material. The flux-cored wires had a diameter of 2.4 mm. The tribological assessment was performed with the Amsler tribotester under dry friction conditions at unit pressures 10 MPa. The use of XPS spectroscopy allowed deep profile analysis of the surface layer. Based on the obtained results developed model of the surface layer for friction couple, hardfaced coating obtained from Fe-Mn-C-B-Si-Ni-Cr alloy – C45 steel. It was observed that the operational surface layer (OSL) of hardfaced coatings contained oxides (B2O3, SiO2, NiO, Cr2O3, FeO, Fe3O4, Fe2O3), carbides (Fe3C, Cr7C3) and borides (FeB, Fe2B).

Opis:: Dental practice today used a lot of different materials. This paper evaluates tribological and mechanical properties of two dental materials CeramX and I-Light. Tribological analysisad of samples was conducted at temperature 37°C and in the environment of artificial saliva. The wear rate was evaluated with a ball-on-disc tribotester, in accordance to ASTM G-133 norm. The counterbodies were 6-mm-in-diameter Al2 O3 steel balls. The load of 2, 10 and 20 N was applied. The tests were conducted at 0.15 m/s sliding velocity over a sliding stroke of 1000 m. The changes in the value of the following parameters were measured during the trials: friction coefficient, friction force, temperature and wear depth. After completing the tribological tests the surface of samples was carried out.
