Keywords:
Al-12Si Alloy, Nanocoating, Atomization, electrical and thermal conductivity, electrochemical behavior.Abstract
This work involves study the effect of Al2O3/SiC/ZrO2 nanoparticles coating on behavior of Al-12Si alloy. Electrical, thermal and electrochemical properties have been investigated before and after coating with Al2O3/SiC/ZrO2 by atomization process. Coated layer was identified by AFM and optical microscopy. Nanoparticles coating greatly decrease the electrical conductivity by acting a barrier to transport of electrons through the coated layer. While thermal conductivity was increased by nanoparticles coating due to filling the voids and then easily transport the phonon can occur. Electrochemical properties was estimated by corrosion test in seawater at room temperature and the data indicated that the corrosion resistance increased for coated alloy and get a protection efficiency equal to 85.17% with porosity percentage 8.685%.
