PROPERTIES OF CARBIDE COATINGS OBTAINED IN THE PROCESS OF CASTING PRODUCTS ON GASIFICATION MODEL
Keywords:
carbide coating, high carbon steel, gasification casting model, heat treatment, bending resistance and durability, internal structure.Abstract
The article presents materials for studying the structure and properties of products obtained
with hard-alloy coatings. The composition and properties of steel were studied, the hardness and
microhardness of the surface and underground layers of the casting were studied. The deviations of
experimental and full-scale tests were analyzed. Two-phase recrystallization is the final heat
treatment method for castings. It has been shown that two-phase recrystallization heat treatment
increases the durability of carbide coatings and finished products by 3-4 times.
