Abstract
The advantages of friction stir welding (FSW) are well known from numerous publications. In this work it was proposed to apply FSW in restoration of sizes of copper plates of machines for continuous casting of billets (MCCB) moulds and for the further surface hardening with nickel or nickel alloys. The microstructure of characteristic zones of joints was studied. Application of FSW provides quality joints with sufficiently high mechanical properties of deposited layer. The structure of copper-copper and copper-nickel joints was studied. It was established that in formation of joints the mechanical stirring of metals plays a leading role, and their mutual diffusion affects them to a much lesser extent. Experimental investigations were laid as the basis for development of restoration technology of copper plates with nickel coating. 14 Ref., 10 Figures.
