METHOD FOR PRODUCING COMPOSITION MATERIAL FROM COPPER, TITANIUM AND STEEL Russian patent published in 2019 - IPC B23K20/08 B32B15/01 

FIELD: technological processes.

SUBSTANCE: invention can be used to obtain wear-resistant materials using the energy of explosives (EX), in particular, in the manufacture of friction pairs for operation in non-corrosive environments. Produce five-layer blanks with alternating layers: copper – low carbon steel – titanium – low carbon steel – copper for subsequent explosion welding in a multilayer package of copper layers among themselves on regulated modes. After hot rolling, welded five-layer blanks are produced by explosion welding two multi-layer blanks, each consisting of 6–8 resulting five-layer blanks from copper, titanium and steel. Then a multilayer package is produced of the two obtained multilayer blanks of copper, titanium and steel, which are also connected by explosion welding. Annealing welded multilayer package is produced.

EFFECT: method provides for obtaining a multilayer composite material made of copper, titanium and steel with a low wear rate and ensuring a large amount of permissible wear while maintaining its service properties.
