| Summary: | Parts subject to intense abrasive wear have a short service
life. In the manufacture or restoration of such parts by
electroslag surfacing, strengthening of the deposited
metal is required. The use of ready-made alloying powders
in surfacing increases the cost of the finished part, which
necessitates the search for cheaper materials for alloying
the parts being welded. The study of the efficiency of
alloying the deposited metal through the melted insert,
as well as by direct introduction of alloying powders into
the slag bath has been carried out. Mixtures based on
enriched mineral scheelite concentrate and graphite are
used as alloying powders. |
