Modern trends in tungsten alloys electrodeposition with iron group metals

Abstract: Theoretical and applied studies of tungsten alloys with iron group metals (Me-W) are being carried out worldwide, in the light of their versatile applications. The aim of this paper is to provide an overview of the works on electrodeposition of tungsten alloys with iron group metals, their properties and applications. There are 221 papers reviewing on the following theoretical and practical topics: chemistry of electrolytes used for electrodeposition, codeposition mechanisms, and properties of electrodeposited tungsten alloys. In addition, the formation of W(VI) and iron group metal (Me) complexes (polytungstates and complexes of Me(II) and W(VI)) with citrates and OH− is analysed based on the published data and the calculated distribution of species as a function of pH (ranged from 1 to 10) is provided for solutions with/without citrates. The adduced data are correlated with the compositions of electrodeposited alloys. Various codeposition models of tungsten with iron group metals described in the literature are critically discussed as well. The peculiarities of the structure of tungsten alloys and their thermal stability, mechanical, tribological, and magnetic properties, corrosion performance, their applications in hydrogen electrocatalysis, template-assisted deposition into recesses (aimed to obtain micro- and nanostructures) are also reviewed and mapped.

Microarc oxidation of magnesium alloys: A review

Abstract: This review summarizes the experience of using plasma electrolyte methods to improve the properties of magnesium alloys intended for designing components of various devices, medical equipment, etc. The emphasis is placed on the formation of coatings by both the “standard” microarc oxidation (MAO) method and its version using electrolytes containing suspended powders of different natures and degrees of dispersion. This modification can significantly expand the range of application of magnesium alloys in medicine, biology, the instrument-making industry, mechanical engineering, and living systems technology.

Corrosion behavior of severely plastic deformed magnesium based alloys: A review

Abstract: The purpose of this paper is to provide an overview of the impact of the microstructural modifications via severe plastic deformation on the corrosion behavior of magnesium and its alloys, especially when they are considered to be biodegradable materials. Mechanical processing involved in grain refinement modifies textures and residual stresses of materials which have their own impacts on corrosion behavior as reported in a large number of studies. However, the existing literature on the influence of microstructure on corrosion resistance is often contradictory, which discloses a lack of knowledge in this area. In this article the effects and contributions of critical factors such as the grain size, texture, residual stress and second phase distribution, affected by severe plastic deformation, on the magne-sium corrosion behavior is reviewed in order to find a relation between the microstructure and corrosion resistance.

Effect of heating on palygorskite and acid treated palygorskite properties

Abstract: The behavior of palygorskite as an adsorbent or catalyst support is governed mainly by the magnitude of its surface areas and degree of surface activity. Most heterogeneous catalytic reactions take place at elevated temperatures. It is important and necessary to known the possible changes in the physicochemical properties and hence the catalytic activity due to the thermal treatment. The present work investigates the effect of heat treatment on the surface and textural properties of palygorskite and acid activated palygorskite. Samples were heated at the required temperatures (150°C, 350°C, 550°C and 750°C) for four hours. The chemical analysis, X-ray diffraction, thermal analysis, and textural properties evaluated on the basis of the nitrogen adsorption have been reported for different samples. Acid-treated samples showed a shift of the DTA curves maxima to low temperatures with increasing acid treating time. The weight loss observed between 300–900°C was approximately half of the value observed for the untreated mineral over the same temperature range. On heating, water molecules are removed causing changes in the BET surface area and the porosity. The modification as a function of the temperature differs with the samples. However, at 750°C, a noticeable decrease of the surface area, which is attributed to closure of the mesoporosity, was observed for all the samples.

Stimulation of the germinability of seeds and germ growth under treatment with plasma-activated water

Abstract: The results of the effect of the gas discharge treatment of water on the initial growth stages of rye seeds and flowers of Zinnia annuals are presented. Gas discharge activation is shown to yield an increase in the degree of swelling (up to 50%) and germinability and to affect the length of the germs and roots.
