Abstract

Abstract The present study for the first time demonstrates that friction surfacing can be applied as a process of mechanical alloying. The Zn powder was added to the coating through insertion of the hole in the consumable AA5083 rod. Zn dissolution and production of a solid solution during friction surfacing confirmed by X-ray diffraction. The results showed a solid solution, which was formed during friction surfacing and decomposed due to artificial aging, resulting in the formation of AlMg4Zn11 precipitates. Moreover, abnormal grain growth was observed in the coating after solid solution and aging treatment.
