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

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.
