Surface Modification of Multilayer Coatings Ti-Al-Cr and Hydroxyapatite on Calcium Phosphate Cement with Sol-Gel Method

Implan gigis based on metal still has weaknesses. new development is currently developed with the surface modification of multilayer coatings ti-al-cr and hydroxyapatite on calcium phosphate cement (cpc) for implan gigi application. objective: to analize the thickness of multilayer coating alloy ti-al-cr and hydroxyapatite on cpc synthesis by sol-gel method. methods: scanning electron microscopy (sem) was conducted to analyze the thickness and morphology of microstructure layer formed on cpc. result: sem showed that coating ti-al-cr on cpc successfully formed 1лm of thickness and showed 10лm of hydroxyapatite. conclusion: the innovation of modification surface multilayer coatings ti-al-cr and hydroxyapatite on cpc was successfully done by sol-gel method with a variety thickness.
