The practical value of the work.

1. A new method for measuring the electrode potential of metals during

frictional interaction in corrosive media (Ukrainian patent №111429), which made

it possible to increase the accuracy of measuring the tribopotential, in particular in

low-conductivity media, and a method for determining wear intensity of passive

materials under polarization currents tribocorrosion (Ukrainian patent №120878).

2. The efficiency of using galvanic composite nickel coatings for protection

against tribocorrosion of aluminum alloy D16T in acidic solutions (wear is reduced

by ~ 7.0 times) and low-alloy steel 17Mn1Si (wear is reduced by ~ 5 times).

3. It was found that doping of the hard alloy of the WC – Ni system with

chromium carbides (1% Cr3C2) increases the resistance to corrosion by 1.4–3.7

times and tribocorrosion (by ~ 15%) depending on the acidity of the medium. The

research results were applied during the production of parts operating in conditions

of corrosion and mechanical wear, at the state research and production enterprise
"Alcon-Tverdosplav ".

4. The efficiency of plasma surfacing with Fe − Ni-based powders for
restoring and improving the performance of the surfaces of shut-off valve elements

in hydrogen sulfide and ammonium media has been established. Details with

applied coatings have passed experimental and industrial inspection at PAE

"Konotop Rebar Plant",

5. To increase the wear resistance of tribocouples, it is proposed to use

additives of silver and zinc and magnesium nanoparticles to lubricants operating in

drill bit assemblies. The obtained lubricating compositions passed the experimental

and industrial test at LLC "Universal Drilling Equipment".
