MODERN FUNCTIONAL MATERIALS FROM NANOSTRUCTURED BAINITE MATRIX AND INCREASED TRIBOLOGIE PROPERTIES
Journal Title: Проблеми тертя та зношування - Year 2016, Vol 70, Issue
Abstract
Conformities to law of forming of nanostructure matrix was investigate in wearproof high-chromium cast-irons, mechanical, physical and chemical, tribology properties are conditioned the presence of elements of nanostructure. Disintegration oversaturated by carbon and alloying elements of metastable austenite in intermediate area of temperatures results lead to forming of nanosize bainite matrix and provides the high complex of mechanical properties (high indexes of durability, to hardness, at the maintenance of impact toughness), increase of abrasive and shock-abrasive wearproofness of removable details of metallurgical equipment from high-chromium cast-irons, allows to decrease content of chrome and other expensive and scarce alloying elements, increases the term of service.

INVESTIGATION OF FRICTION SURFACES OF WORKING ORGAN SOIL-CULTIVATING AGRICULTURAL MACHINES
The research was done of friction surface and composition of secondary structures, which formed during the abrasive wear of structural materials.
SKIN SURFACE EXTRUSION/INTRUSION STRUCTURE AS AN INDICATOR OF AGING AIRCRAFT FATIGUE
A new method for fatigue damage detection is proposed. The new method extends earlier proposed and verified approach for fatigue damage assessment based on the quantitative analysis of surface deformation relief on alumi...
ТО THE QUESTION OF THE EVALUATION OF THERMAL BALANCE OF SOLID DISCS OF BRAKES IN THE SUBCATEGORY OF VEHICLES
The tribological system, to which the disk-and-shoe brake relates, is a complex system with its hierarchical ordering. This system consists of a set of subsystems that interact with each other in a single field. The latt...
ENERGYLOADING OF VARIOUS TYPES OF DISCS IN BRAKE DEVICES OF LIFTING AND TRANSPORTING MACHINES (PART TWO)
The accident-free and safe operation of lifting and transporting machines largely depends on the reliable operation of the friction pairs of brake devices. The experience of operating has showed that the wear-friction ch...
STATUS OF TRIBOLOGICAL SYSTEM «VCH50 - MOTOR OIL - AO20-1» IN THE CONDITIONS OF INSUFFICIENT LUBRICATION
The results of tribotechnical tests of the tribological system of materials "VCH50 - motor oil - AO20-1", which was investigated in tribo-conjugation "neck-insert" using full-scale specimens of the details of the crank-a...
