Sealing of leaks by gas-dynamic spraying – addition and alternative to welding

Abstract

Possibility analysis data of application gas-dynamic sputtering technique to eliminate defects in complex metal objects are covered. It is shown that usage of zinc addition in the powder composition allows for a hermetization problem efficient solution and for defects elimination with the help of DIMET portable equipment for metal coating sputtering.
