Opis:: Purpose: Corrosion resistance of titanium used in metal-ceramic restorations in manufacturing is based on the presence of oxide layer on the metal surface. The procedures used during combining metallic material with porcelain may affect the changes in oxide layers structure, and thus anticorrosive properties of metallic material. The aim of the study was an evaluation of potential changes in the structure and selected corrosion properties of titanium after sandblasting and thermal treatment applicable to the processes of ceramics fusion. Methods: Milled titanium elements were subjected to a few variants of the processes typical of ceramics fusion and studied in terms of resistance to electrochemical corrosion. The study included the OCP changes over time, measurements of Icorr, Ecorr and Rp as well as potentiodynamic examinations. Surface microstructure and chemical composition were analyzed using SEM and EDS methods. Results: The results obtained allow us to conclude that the processes corresponding to ceramic oxidation and fusion on titanium in the variants used in the study do not cause deterioration of its anticorrosive properties, and partially enhance the resistance. This depends on the quality of oxide layers structure. Conclusions: Titanium elements treated by porcelain firing processes do not lose their corrosion resistance.

Opis:: The decomposition of mixtures of polystyrene, polyethylene, and motor oil was studied at 470 - 510°C in a flow-through setup supplied with a fluidized bed reactor and a cascade of receivers. The aim of the work was to determine the role of the fluidized bed in the reactor, in the process of degradation of plastics in the cases where it was only a carrier of heat for the endothermal process of pyrolysis or it was both a carrier of heat and a catalytic bed for the process. The effect of the catalyst granulation and of the method of the organization of work in the reactor on the yield of the process and on the composition of the products obtained, was also studied. In the cases where Al2O3 of granulation 0.2 mm was used as a fluidized bed catalyst the liquid products of the decomposition of the polymers contained mainly alkyl-aromatic derivatives of styrene, benzene and alkane hydrocarbons. If nano-Al2O3 was used as a catalyst and it was introduced into the reactor with a stream of raw materials, the obtained products were solids, composed mostly of styrene and alkene hydrocarbons.
