Abstract: The purpose of this study is to compare the dissimilar joints of pure titanium to stainless steel achieved by different intermediate materials like aluminum, copper and nickel. Due to the metallurgical incompatibility between those base materials, it has been very difficult to produce reliable joints due to the formation of FeTi and Fe2Ti intermetallic compounds.

Abstract: The paper solves the cause and character of the damages of tubes, or evaporator tubes made of refractory carbon steel L290NB, used for the evaporators of combustion chambers of steam boilers used for production of steam, and necessary for subsequent production of electricity. Based on the evaluation of steel samples defected by perforation with incrustation deposit, the mechanism degrading the material of evaporator boiler tubes was discovered. [..] Read more

Abstract: The influence of surface preparation of steel 41Cr4 on the structure and corrosion resistance of the zinc coating has been presented in the paper.

Abstract: Zn and Zn-based alloys attract interest due to an ability to protect steel surface against corrosion. Thin surface layer of a protective zinc alloy is usually prepared by hot dip galvanizing and acts as a barrier against corrosive environment or as a sacrificial anode in case the bare steel surface is exposed.

Abstract: Research in the field of magnetic materials based on Nd-Fe-B is focused on the improvement of certain magnetic characteristics by alloying of suitable elements (Co, Dy, Pr, Cu), extending the thermal stability of these permanent magnets, improving their corrosion resistance and the creation of nano-structure modifications. Magnets based on Nd-Fe-B are susceptible to corrosion, especially in humid atmospheres. [..] Read more
