Abstract

It is a survey-analytical article, which describes a number of criteria of limit states (LS) of complex objects and identifies methods to measure all the parameters necessary for it practical use. It presents the energy theory of LS of tribo-fatigue and mechanothermodynamical (MTD) systems, taking into account the interaction dialectics of efficient energies and therefore irreversible damages under fatigue loading, friction and temperature influence. The fundamental laws of the LS at the combined effects of multiparameter power factors and the environment are analysed. The experimentally grounded (over 600 experimental results) fundamental MTD function of forecast evaluation of different LS (static, fatigue, contact fracture) for pure metals, non-ferrous alloys, constructional steels and polymer materials is presented.

Keywords

LS, tribo-fatigue system, MTD system, theory of strength, criteria of LS, effective energy of potential deformation, Λ-interaction of effective energies (damages), MTD function of critical states, multicriteria diagram of LS of tribo-fatigue systems

Abstract

The method of correcting software hysteresis piezoscanner atomic force microscope was proposed. The algorithm for correction was used for the samples of silicon, mica, polysulfone, and human erythrocytes, and platelets. It is shown that the proposed method can effectively eliminate the difference between the curves of supply and discharge of the working area due to piezo hysteresis and is valid for different delay times between measurements at neighboring points of these curves.

Keywords

piezo hysteresis, static force spectroscopy, the point of contact

Abstract

New parameter for assessment of structural quality - the measure of structural quality μσPms by the residual mechanical stability Pms is offered. It exhibits their residual possibility to resist embrittlement under the stress concentration. The analysis of changes in structural quality of a number of alloys under the effect of two types of stress raisers at uniaxial tension and static bending is executed.

Keywords

brittle strength, stress raisers, mechanical stability, tendency to embrittlement, structural quality

Abstract

The main idea of the article is to generalize the results of studies of the formation of the steel coatings produced by Hypersonic metallization, defining rational modes of recovery and hardening of transport machinery and technological equipment technologies. To achieve this goals the installation of hypersonic metallization model ADM-10 was used, sprayed materials - steel wire 95H18SH (AISI 440-C) and 40H13 (AISI 420). To increase the adhesive strength of coatings with the substrate an intermediate layer of an alloy H20N80 was coated. The studies revealed that increasing of initial temperature of spraying gas enhances the aerodynamic forces acting on a particle of the molten metal. Increasing of the nozzle radius enhances the maximum speed of the particles by extending the distance of dispersing. Activation process of the electric arc metallization by heating of the
atomizing gas allows to increase the speed of the particles smaller than 40 microns, essentially without effect on the speed of the larger particles. Studying of density and adhesion of deposited coatings showed that if the spraying distance increases more than on 200 mm and over, the porosity increases sharply, and the bonding
strength decreases. Therefore advisable to limit spraying gas temperature and pressure at combustion chamber of the Hypersonic metallization installation to the size of 2 300-2 500 K and 0,6-0,8 MPa respectively. Amount of oxygen in the coating at hypersonic metallization is 1,5-2,0 times less in comparison with the traditional method of electric metallizing. parameters of the hypersonic metallization process and displacement speed of the metalizer which provide quality coatings spray wires of steel alloys were defined.
