Formation of Ti-Cu-Based Intermetallic Coatings on the Surface of Copper During Contact Melting

摘要

An explanation is proposed for the phenomenon of contact melting in the Cu-Ti system and is substantiated experimentally. The phase composition and relative wear resistance of a coating created by contact melting at the boundary of a compound formed by the explosion welding of a copper-titanium composite are determined. It is shown that the main structural components of the coating are the intermetallides beta TiCu4 and TiCu2.
