Research of the melting zone of the relit – cupronicel composite alloy when surfacing metallurgical equipment parts using the furnace method

Abstract
With the furnace surfacing method, a composite alloy is obtained, consisting of reinforcing particles of tungsten and cupronickel carbides, which, after exposure to the melting temperature of the binder alloy, form a wear-resistant layer on the surface being hardened. It has been established that in the zone of connection of the composite alloy relit – cupronickel with the steel surface of the part, in the absence of conditions that guarantee auto-vacuum cleaning of the surface from oxides, an interlayer with an imperfect crystal structure is formed, which leads to delamination of the deposited alloy. It has been experimentally shown that the use of additional control for the gas tightness of the surfacing space makes it possible to improve the quality of the deposited surface when furnace hardening of metallurgical equipment parts with the composite alloy relit – cupronickel.
