Fabrication and Microstructure of Diffusion Alloyed Layers on Pure Magnesium Substrate/ Wytwarzanie I Struktura Dyfuzyjnych Stopowych Warstw Na Magnezie

Abstract: Alloyed layers on pure magnesium were created by means of the heating of the magnesium sample covered with Al+Zn powders mixture containing 20 wt.% Zn and 40 wt.% Zn in vacuum furnace. The microstructure and related composition of the alloyed layers were investigated using optical microscopy and scanning electron microscopy equipped with an energy dispersive X-ray system (EDS). The results revealed that the microstructure, thickness and microhardness of the obtained layers depended on the Zn content in the pow… Show more

“…The experimental results presented in this paper show that the zinc-enriched layer can be formed on magnesium or AZ91 by thermochemical treatment using a medium containing the zinc chloride and potassium chloride mixture. It is noteworthy to mention that the use of zinc chloride as the source of zinc atoms during heat treatment is a less costly method than the use of metallic powders as a source of diffusion elements [27][28][29][30][31][32][33][34][35][36]. Zinc chloride is cheaper and more easily available than metallic powders.…”

“…During heating, active atoms from the outside source diffuse into and react with magnesium, which results in the formation of intermetallic phases in the surface layer. The solid media used in thermochemical treatment include pure alu-minium powder or aluminium and zinc powder mixtures [27][28][29][30][31][32][33][34][35][36]. An alloyed layer fabricated in pure aluminium contains Mg-Al intermetallic phases.…”

“…Large numbers of strategies have been developed to prepare Mg-Al alloyed diffusion coatings, which can be divided into two categories: one-step processes and multi-step processes. One-step processes include packed powder cementation [14,[16][17][18][19][20][21][22][23], chemical vapor deposition (CVD) [24,25], vacuum aluminizing [26][27][28][29], laser cladding [30][31][32], etc. Among them, packed powder cementation has been widely used due to its simplicity, low equipment requirement and good applicability for complex-shaped components.…”
