Two approaches to reception surface nano-structured metals: solid-state hydride synthesis and adsorptive modifying

Article preview

In this work the technique of nano-structured surface modification of metal based on sequential and mixed treatment aluminum powder with steams of different cationic tensides was experimentally proved. Also possibilities of solid-state hydride synthesis nano-structured metals with using at the first stage of restoration steams of hydrophobizing silicon-organic liquid were studied.

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.

Influence of nanostructured metal additives on antifriction properties of industrial oil

Article preview

Measurements of integrated parameters of friction and their comparative analysis by method of acoustic emission in a ultrasonic range of frequencies (20-300 kHz) for pair friction metal – metal with lubricant in the form of the industrial oil filled by traditional additives (coal) and nanostructured powders on the basis of aluminium are carried out. Influence of firm additives on displacement of a region of dry friction on curve dependences of a parameter of friction from pressure in a zone of contact is estimated. Nanostructured sample on the base of the aluminium powder PAP-2 containing on a surface two-component nanofilm active cationic tensides, which improve antifrictional characteristics of industrial oil I-20 in 4-7 times is revealed. Representations about the mechanism of action of additives on antifrictional properties of oil are developed.

Nanostructural modification and regulation of metal surface properties based on the effect of low molecular weight surfactant sublayer

Article preview

Data on reactivity of different powders of aluminium depending on the program of nanostructure modification are analysed. Rows of increase of reactivity modified aluminium powders are obtained. Samples, exceeeding the initial aluminium powder on activity, are exposed. The effect of passivation of steel in coating containing a «triamon» under-layer is established.

Application of press filters at the stage of copper-nickel concentrates dehydration

Article preview

The paper describes the operation and control system of modern press filters on the example of LaroxPF filters installed in the roasting shop of Pechenganickel Combine. The main problems of improving and optimizing the operation of press filters are identified and a method of their solution is proposed by drawing up regression dependencies for the main characteristics of filter operation based on experimental data.
