Effect of Contact Melting Regime on Structure and Properties of Coatings of the Copper–Titanium System

Abstract

The effect of temperature and duration of contact melting on composition, structure, and properties of coating of the Cu–Ti system is studied. It is shown that an increase in temperature with short exposures facilitates preparation of a finer structure and an increase in coating hardness. An increase in contact melting duration leads to structural component coagulation and a reduction in coating average hardness values. Equations are obtained for determining processing parameters for explosive welding and hightemperature heating regimes for forming a coating of required thickness and phase composition.
