The paper is focused on modification of surfaces properties by laser cladding. To follow the corrosion behavior in different media of laser cladding layers made of nickel based alloy Ni - Cr - B - Fe - Al. It was studied ...

This paper aims to study bulk severe plastic deformation processes capable to produce ultrafine grain and also nanostructured 3D materials, interesting for processing in current industry. Samples of copper alloy were ...

Phosphate conversion coatings are used on the galvanized steel. By forming a thin protective film on the surface of the steels this treatment enhances corrosion resistance. This paper presents studies on phosphate ...

A promising way to use biomass for the production of heat, electricity and other biofuels is through biomass gasification. In the gasification process, the chemical energy of the solid fuel is converted into the chemical ...

In the paper the obtaining of nitinol by pressing and sintering of a mixture of nickel and titanium powders is presented. The fabrication of NiTi alloys by powder metallurgy allows avoiding the usual problems related to ...

The ferro-niobium composite layers in cobalt matrix were obtained by cathode depositing from electrolyte solutions on steel base. The electrolyte included in its composition cobalt sulphate and cobalt chloride, boric ...

The paper presents the results of the laboratory research on the chemical composition and crystallographic texture in 3% Si steels and their influence on the level of magnetic losses in the final sheet. The magnetic ...

The paper focuses on review investigations of electrodeposition processes of metallic coatings containing dispersed nanosized particles. The nanosized particles, suspended in the electrolyte by agitation and/or use of ...

Since the metals deposited in the teeth during formation and mineralization processes are to a large extent retained, human teeth receive a considerable attention as indicators of heavy metal exposure. The objective of ...

The HfO2 thin-film is a very promising gate dielectric material for last generation transistors. The paper presents the thermal decomposition of hafnium ethoxide used as molecular precursor for obtaining hafnia thin ...
