Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The article deals with results of investigation of properties of nickel and cobalt alloys, deposited on copper or its alloys. Investigations of corrosion resistance of these alloys at different types of corrosion (solid, contact, crevice, cavitation-erosion fracture), as well as their antifriction properties and adhesion strength showed that the most acceptable as to the combination of properties are alloys NKh16SR2 and KKh30N6VSR. The technology of automatic plasma-powder surfacing of these alloys on aluminum bronze Br.AZhNMts9-4-4-1 was developed providing a quality joining of the deposited metal and the base one. The technology and equipment found application in surfacing of parts of ship pipeline fittings. 4 Ref., 1 Table, 6 Figures.
Keywords: plasma-powder surfacing, surfacing on copper, surfacing technology, cobalt- and nickel-based alloys, corrosion, antifriction properties
