Specific Features of Interface Formation for Metal-Ceramic Coatings on a Steel Base

摘要

Mechanism of pearlite formation in the base metal in melting of coatings based on self-fluxing alloys was studied. A zone in the form of a complex carboboride (Fe, Ni, Cr, Si) (BC) in the multilayer coating-steel interface was found and studied. The effect of pore space filling by needles of carboboride phases of the solid interlayer was revealed. It was shown that the coating composition and characteristics of strengthening additives (composition and dispersity) affect the structuring of the transition zone.
