Formation of Aluminium Surface Layers’ Structure during Laser Alloying with Copper and Cobalt Powders

摘要

Possibility of quasi-crystal decagonal phase formation in the surface layers of aluminium during laser alloying is demonstrated. Alloying is carried out by mixture of copper and cobalt powders with atomic ratio 1:1. The phase state of laser alloying zone is thermally stable up to the temperatures close to the matrix melting point.
