Opis:
Computer 3D modelling allows designing or mapping objects and then their photorealistic visualization. In the programs for creating 3D graphics a user often loses judgement as to which technique to use during the process. It is also a major problem in teaching graphics, because the final result can be obtained by various methods using tools available in the programs. This paper presents and discusses the examples of the usage of computer visualization in teaching technical subjects on science faculties. For this purpose CAD programs, such as Inventor and AutoCAD were used. The advantages of 3D over 2D design were described and the analysis and evaluation of the available tools for 3D modelling and computer visualization were conducted. In the final part of the work selected examples of computer visualization are presented, in the context of supporting teaching the students of science fields of studies.

Opis:
Tribological behaviour of coatings obtained from eutectic alloy Fe-Mn-C-B-Si-Ni-Cr was studied. The coatings were obtained by the method of gas metal arc welding (GMA) with use of powder wire. GMA welding method is widely used for the regeneration of machine parts. Eutectic Fe-Mn-C-B-Si-Ni-Cr alloys can be used to obtain high quality coatings resistant to wear and corrosion. Pin-on-disk dry sliding wear tests at sliding speeds 0.4 m/s and under load 10 MPa were conducted for pin specimens. During friction a typical tribological behavior was observed. The mechanism of wear was mechanical-chemical.

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:
Computer animation has a positive effect on memorizing knowledge by students. Used in the process of teaching of technical subjects, it is conductive to the development of mind. Animation allows to familiarize the students with the schemes of solving technical problems and shows the mode of operation of machinery and equipment. In the technique, animations are used, inter alia, in the processes of designing, engineering calculations, visualisation and monitoring technological processes and visualisation of assembly processes. The article discusses the role of computer animation in the teaching process and the examples of applications using computer animation and supporting the teaching process of technical subjects. Selected examples of technical processes in both computer-aided design and manufacturing programs as well as in graphics and animation programs are presented.

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.
