Additional methods of surface modification for hardening and aloying, such as laser treatment (LT) and electric spark alloying (ESA), which result in the hardness increase and to increase in probability of formation of nanostrucutres and operational properties goods, were chosen. Technological condiotions were determined for UIT and for the sequence of use of LT and UIT (on X12MF steel specimens) and ESA and UIT (on 20GL steel specimens).5481 Product Description popup.authors Запорожець Олег Іванович Прокопенко Георгій Іванович popup.nrat_date 2020-04-02 Close
