CONDUCTING CORROSION RESISTANT COVERING ON THE BASIS OE NICICEL EOR CON¬TACTS OE SYSTEM OE ACOUSTIC PODVODY BEACONS OE AIRCRAETS

The microstructure, porosity, microhardness, the adhesion strength of a covering on the basis of Ni received by method of powder gasdynamic spraying are investigated. Tests of a voltage drop on an electrical link with the studied covering in a conducting medium on the basis of ocean water depending on a temporary factor are carried out It is revealed that the stable behavior of electric potential (no more than 0,5 V) at deposition on an effective area of contacts from VT-3-1 alloy provides their reliable electrochemical protection in the environment of ocean water
