Bio-CAM 2017 Effect of AC-Anodizing parameters on AZ80 in alkaline solution Nur Suhaily Azmi a , Mohd Nazree Derman a *, Mohammad Amerul Azree Jamil a , Jasni Mohamed Ismail b a, School of Materials Engineering, Universiti Malaysia Perlis, 02600 Jejawi, Arau, Perlis, Malaysia b Institute of Nano Electronic Engineering, Universiti Malaysia Perlis, 01000, Kangar, Perlis, Malaysia. Abstract AC-anodizing is carried out on magnesium alloy AZ80 in sodium silicate solution (Na 2 SiO 3 ) with different parameters which are anodizing voltage (5 V, 10 V, 15 V, 20 V, and 25 V) and temperature (5 ℃, 15 ℃, 25 ℃, 35 ℃, and 45 ℃) of Na 2 SiO 3 . The effect of the parameters is studied on the AZ80 surface. The microstructure analysis of the AZ80 surface observed using optical microscope and scanning electron microscopy (SEM) determine porous AZ80 surface and flake-like magnesium silicate, Mg 2 SiO 4 . By using X-ray diffraction (XRD), the phase composition of AZ80 after AC-anodizing process indicated Mg 2 SiO 4 , SiO 2 and MgO. © 2019 Elsevier Ltd. All rights reserved.

Most commonly used alloys are steel, aluminium (Al) alloys and magnesium (Mg) alloys. Mg alloy is highly demanded in industrial field as the alloy is categorized in lighter materials. Some outstanding advantages of Mg alloys are high strength-to-weight ratio, high thermal conductivity, good electromagnetic shielding and facile recycling [1].Thus, Mg alloys have been widely used as construction on materials in automotive, aerospace computer and cell phone industries [2]. However, Mg alloys show poor corrosion and wear resistance which limits their spread usage. Therefore, surface treatment such as anodizing is essential to improve the properties in Mg alloys [3]. * Corresponding author. Tel.: +604-9798154; fax: +604-9798178.
