Publikováno v: Materials Science. 53:789-795

We study the influence of its microstructure of an Al–Cu–Mg alloy sprayed by the electric-arc method in the intact state and with oxide-ceramic coating on its corrosion resistance in synthetic weakly acid media. It is shown that the increase in t

Influence of the Size of Drops and the Velocity of Flow on the Structure and Properties of Electric-Arc Coatings

Autor: Ya. Ya. Sirak, Kh. R. Zadorozhna, V. М. Hvozdets’kyi, Ya. М. Dem’yanchuk

Publikováno v: Materials Science. 53:702-708

We show that, as the pressure of a metal–air jet increases from 0.6 to 1.2 МРа, its velocity increases from 300 to 600 m/sec. It is established that with increase in the velocity of the flow of particles, the time of transportation of drops from
