RESEARCH OF POSSIBILITY OF CLEANING OF STEEL OF 40Х FROM SUPERFICIAL TAPES AT SOLDERING IN SALT BATHS

V.V. Kosenko, A.S. Kobzev
Annotations languages:

As a result of the conducted researches compositions and temperature-temporal modes are certain in the processes of fluxing became 40Х fusions of borax technical, to the gumboil of PV 200 and chlorine barium. On the degree of growth of activity gumboils are disposed in the following order: chlorine barium, a borax is technical, PV 200. It is shown that with the increase of time of флюсування intensity and degree of cleaning of surface became 40Х from tapes increased.
Keywords: high temperature soldering, composition of gumboil, cleaning degree, superficial tapes, temperature-sentinel mode of fluxing, macrophotography, photomicrograph
