Structure of coatings formed by electroexplosive spraying after electron beam processing
Analyzed are dislocation substructures of electroexplosive composite coatings formed on copper surface and modified high intensity electron beam. Formation of multiphase high defect structure on the coating surface layer is revealed. It is established that in Cu and Mo - W - Cu coatings second phases are nanosize particles of molybdenum and tungsten. In coatings of Mo - Cu - C, W - C - Cu and TiB 2 - Cu formation of the second phases particles of Mo 2C and WC carbides, and Ti 2B 5 boride of titanium are detected.
