Abstract

The coating of the TiB2-Ni-Ag system is obtained on a substrate of a copper e1ectrica1 contact by simu1taneous e1ectrica1 exp1osion of si1ver and nicke1 foi1s a1ong with the TiB2 powder 1ocated on the surface of the foi1s. The structure and the transition area between the coating and the copper substrate are investigated using scanning e1ectron microscopy. The coating has an average thickness of 160 ^m and is characterized by a structure with microcrysta11ine and nanocrysta11ine TiB2 inc1usions 1ocated in a si1ver- and nicke1-based matrix. There are periodic wave-1ike structures with micrometer-sized waves at the boundary between the coating and the copper substrate formed as a resu1t of hydrodynamic instabi1ities during the coating process. The nanocrysta11ine structure of the coating at the transition area between the coating and the substrate presents nanosized partic1es of so1id copper, si1ver, and nicke1 so1utions. There are cracks in the copper substrate; they formed by the impact of the shock-compressed 1ayer and extend a1ong the intergranu1ar boundaries.
