The Tribological Investigations of Multicomponent Multilayered Ion-Plasma Coatings Avinit
Abstract
The friction and wear characteristics of sliding friction in conditions of boundary lubrication for coatings, received by ion-plasma method on the heat resistant deformed alloy of АК4-1 type are investigated. Conducted tribological studies of improved designs of multi-component multilayer coatings Avinit in fuel TS-1 media selecting coating materials for precision friction pairsof hydraulical units. Coatings are very effective in increasing the stability of the pair to bores cuffing teasers. Improved coatings have low friction coefficients (0.075 - 0.095) at loads up to 2.0 kN and showed high resistance to wear. More over relative stability increasing achieve 20-80 times, and contrabody wear decrease of 4-5 times.
