This paper studies the structure, composition and morphology of the oxide phases on the surface of the samples St20 steel, passivated in nitrate solutions containing and not containing aluminum ions. It is shown that the passivation of carbon steel with a solution containing aluminum nitrate, surface corrosion and there is no ulcer "healed" the previously formed centers of local corrosion. At the same coatings formed in solutions containing aluminum nitrate, have the highest corrosion resistance as compared with those obtained by other methods of passivation.

Unlike most other brachiopods, craniiforms lack a prominent pedicle, cement to a hard substrate by their ventral valve, and thereby can be easily distinguished in paleontological materials. In this study, we describe a new genus and species from the Porkuni Regional Stage of Northeastern Estonia (Baltica), corresponding to the lower part of the Hirnantian Stage ...

Although Brachiopoda represent a relatively small phylum, they exhibit significant morphological diversity. One of the central issues in understanding the evolution of the ancestral brachiopod body plan pertains to the homologies among body compartments across the different brachiopod subphyla: Craniiformea, Linguliformea, and Rhynchonelliformea. In this context, the pedicle stands out as one of the most ...
