IMPROVEMENT OF THE PERFORMANCE PARAMETERS OF PRECISION FRICTION COUPLES IN THE MAGNETIC FIELD

摘要

The paper considers the possibility to control the restoration and wear processes during friction depending on the location of magnetic poles using electromagnetic techniques. It is shown that both the steel piston and copper cylinder can be restored in the magnetic field separately (without disassembling the mechanism). A method is developed for restoring the friction surfaces in oil modified with different magnetic powders in a pulsed magnetic field. The influence of a pulsed magnetic field on the tribological characteristics of the friction couple in oil with different magnetic nanopowders is analyzed to reveal that the surfaces are the most functional in S/N pulsed magnetic field.
