Development of research of low-dimension metal-containing systems from P.P. Weymarn to our days

Article preview

The article analyzes main laws discovered by P.P.Weymarn (1879-1935) during his work at the Saint-Petersburg Mining University, they are connected with obtaining metal-containing disperse substances with nanometer particle size. It enlists priority papers in this field (1906-1915) and describes peculiarities of P.P.Weymarn scientific school which has several connections to modern research being conducted at the Saint-Petersburg Mining University in the field of «nanotechnology» as well as by foreign scientists. The paper reveals continuity in the field of several objects (disperse metals) and the methodology of studying the properties and stoichiometry of substances depending on dispersity. It provides information on achievements in synthesis of surface nanostructured metals and low-dimension forms of substances in various porous matrixes. Among the studies of the XXI century developing Weymarn’s ideas there can be noted solid-state hydride synthesis of metals, layering of different-sized molecules of ammonium compounds on metals (Al, Cu, Ni, Fe), as well as synthesis of metal nanostructures (Ag, Cu, Bi) using porous glass as a particle size stabilizing matrix. In the latter case, the dispersity of the metal increases while its melting point decreases.

Research of antifrictional properties of industrial oil with additives of the nanostructured metals the acoustic method

Article preview

On data of acoustic method, it’s discovered that dependence of integral index of friction (D) from loading pressure (P) under using of best lubricant with addition of nanostructured aluminium powder after treatment by mixture of alcamon and triamon vapour, doesn’t consist a characteristic peak under small pressures. This dependence is smooth, plain curve and in pressure range (15-55 MPa) is correctly described by equation D=8,5e 0,082P . Alteration of D on exponent low takes place under using of analogous addition on copper powder base and powder copper, which is processed by alcamon, too. Those facts testify about liquid mode of friction.

On the interrelation of water repellent properties and reactivity during oxidation of nanostructured metals based on steel and aluminum

Article preview

It was examined the correlation between water-repellent properties and reactionary properties in the process of oxidation for nanostructured materials, based on steel and industry trademarks of aluminum powder. Analysis experimental data showed, that for samples, which have nanofilms on cationic tensides and silicon-organic compounds on steel there is the symbatic correlation between water-repellent properties of coatings and their protective properties. And samples, based on aluminum, have highest intensivity of oxidation with middle level of water-repellent properties.

Involvement of off-balance reserves of III potash horizon of Starobinsky deposit in mining

Article preview

The paper presents results of feasibility study into recovering non-commercial reserves of mined horizons at the Starobinskoe potassium deposit. Topicality of this task is explained by a rather intensive reserve depreciation at the RUP PO Belaruskaliy Company and the fact that developing new horizons is a capital-intensive task which requires additional geological prospecting activities.

Experience of development and implementation of nanostructured coatings for protection of metal structures at the enterprise of mining industry

Article preview

Symbate (and in some cases linear) correlation has been established between water-repelling and protective properties of currently known nanostructured and conventional paint steel coatings; the surface passivation effect in steel surface with triamon nano- undercoating has been revealed during long-term corrosion tests in industrial conditions. Nanostructured protective coatings have been developed and introduced at mining companies for the first time in the history.

Development and economic justification of the method of extraction of off-balance reserves of the Starobinskoe deposit

Article preview

This article presents an analysis of existing lava pillar excavation methods using selective mining implemented at the fourth potash horizon. A new method is proposed that ensures the recovery of not only economic resources but also non-commercial reserves of the fourth potash horizon. Non-commercial reserves are concentrated in the ninth sylvinite layer, which contains about 14% of the total resources of this horizon. The economic effect of the proposed mining method is up to $13 million for one mining pillar.

Nanostructural regulation and interrelation of water repellent and protective properties of coatings on steel

Article preview

The data on corrosion of Mk.3 steel with different coatings in atmospheric air containing potassium chloride, hydrogen chloride and sulfur dioxide impurities below the maximum permissible concentrations have been analyzed. A linear dependence between hydrophobic behavior and protective properties of coatings applied on steel was revealed both for standard compositions and for compositions with nanostructured filler (1 wt. %) obtained by hydride solid-phase synthesis.

Methods and effects of regulation of protective properties of coatings on steel surface using nanomaterials

Article preview

Corrosion of steel 3 and steel 3 with different coatings in air atmosphere containing impurities of HCl, SO2, KCl (0,04-0,20 mg/m3 , humidity 70-100%) in model conditions by gravimetric method has been investigated. The symbatic dependence between water-repellent properties of coatings and their protective properties has been established. The possibility of fine regulation and increase of protective properties of coatings by using nanofilms of oncationic tensides, base of silicone-organic compounds and nanostructured hydrophobic Si-C-containing fillers in the composition of coatings is shown.

Nanotribology: the effect of the relationship between the energy characteristics of the surface and the antifriction and insulating properties of adsorbed cationic surfactants

Article preview

Literature data on the relationship between the energy characteristics of the surface (surface tension, bonding energy of surface atoms) with antifriction and insulating (protective) properties of ionogenic surfactants (surfactants) have been analyzed. Experimentally the tendency of strengthening the lubricating effect has been revealed in process of increasing the bond energy of the N1S characteristic level of cationic surfactants adsorbed on the metal; the effect of essential increase (~ by 2 eV) in the N1S bond energy has been revealed in case of joint adsorption of cationic surfactants with different in value hydrocarbon radicals at the nitrogen atom. The bonding energy was determined from measured X-ray photoelectron spectra; the lubricating effect was evaluated in tests on a high-speed conveyor at low loads in dilute aqueous solutions (about 0.01 % surfactant).
