The characteristics of Magnesium-Lanthanum alloy obtained by an electrochemical process

Résumé

In this work, Magnesium-Lanthanum alloy was synthesized by an electrodeposition technique using an aqueous solution, based on Magnesium chloride hexahydrate and Lanthanum(III) Nitrate at a voltage of 4 Volts. A copper cathode plate is used for the deposition of the Mg-La alloy. The as-prepared powder was characterized by scanning electron microscope (SEM) to describe the morphology, energy dispersive spectroscopy (EDS) to determine the chemical composition, X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectra in order to define the chemical structure. Morphological description reveals the formation of heterogeneous chemical structures of very small size on the surface of the sample. EDS analysis indicates the presence of Mg, La and O as major elements and Cl as minor element in terms of weight percentages. X-ray results showed the existence of two distinct phases, Magnesium Hydroxide (Mg(OH)2) and Lanthanum hydroxide (La(OH)3), from the obtained deposit. FTIR analysis confirms the presence of the two phases identified in XRD diffractogram and it can be exhibited by clear peaks.
