durability of steel

Дослідження фретинг-корозії зміцнених поверхнових шарів, отриманих фрикційною обробкою

It’s show, that the friction hardening essentially increases durability of steel in the fretting- corrosion. So, the wear resistence increases in 1.7 times after research without lubrication pares steel 40H — BrA10G4N4 and steel 40H — steel 30HGSA and in 3.3 and 4.6 times respectively after research with oil MS-20. Only the first specimen of pare had hardened, the second specimen had grinded.
