ABOUT POSSIBILITY OF ELIMINATION MICRODROPLETS OF VACUUM ARC OF INPUT ENERGY INTO THE ZONE OF THEIR TRANSPORTATION

Abstract

Briefly reviewed the known methods of reducing the amount of microdroplets in a vacuum arc coatings. It has been shown that they do not allow to completely eliminate the microdroplets of the plasma stream. The possibility of removing the drip phase vacuum arc discharge by evaporation it when entering the microwave energy in its transportation zone was considered. Vacuum arc apparatus for implementing this method was proposed. The estimation of microwave energy required to evaporate droplets of titanium at a current of arc 100 A was done. Unaccounted the factors that can lead to lower of obtained value were considered.
