Abstract
The purpose of this study is to compare the characteristics of hydroxyapatite sol-gel coating of stainless steel in two different solutions named hank’s solution and sodium chloride solution media with the same mol and volume used. Besides that, the corrosion rate of uncoated and coated stainless steel samples immersed in hank’s solution and sodium chloride solution are evaluated in order to declare the better one in revealing corrosion resistance properties as this is the main point of coating process is done on the metallic substrate like stainless steel. The measured stainless steel plates are coated by controlling few parameters during the process such as withdrawal speed, number of coating layer and immersion time. The formation of coating layer, the surface morphology and cross-sectional study on the substrate along with the corrosion rate of both uncoated and coated substrate are investigated by Potentiodynamic Polarization method, Scanning Electron Microscope (SEM), and Energy Dispersive X-Ray (EDX). Throughout this project, the comparison is done between uncoated and coated stainless steel as well as the characteristics of coated stainless steel in two different solutions which are hank’s solution and sodium chloride solution. The results show hydroxyapatite sol gel coating samples possess better corrosion polarization resistance in hank’s solution compared to in sodium chloride due to wider passive region.
