FIELD: metallurgy.
SUBSTANCE: coating for boroaluminising of steel products, which includes active and protective coating. Active coating includes the components at the following ratio, wt %: boron carbide 78-88, aluminium 8-18, and sodium fluoride 3-4. Water is used as bonding agent for preparation of active coating. Protective coating includes EVT-100 enamel and aluminium oxide in ratio of 1:1. Silicate glue and water in the ratio of 1:1 are used for preparation of protective coating.
EFFECT: improving microhardness and thickness of boroaluminising layer, as well as easier preparation of active coating.
