ABSTRACT
In this study, This study report the preparation of alumina matrix coated with hydroxyapatite and their evaluation as biomaterials. The first hydroxyapatite powder is made by Dry Method. And then hydroxyapatite sol is made by attrition mill due to decreasing the size of hydroxyapatite. the second prepared alumina was coated with HAp sol for 10–50 seconds. And then, the structures tested their mechanical and biological properties. First, Compressive strength and hardness evaluates as measuring the mechanical properties. According to adding the HAp, Compressive strength shows increased tendency and indicates up to a maximum value of 122 MPa in this study. However, hardness indicates low value which is that of Monolithic alumina, because this hardness value is measured HAp located on the surface of alumina. Second, measuring the biological properties is observed Calcium growth on the structure surface. When bathed in simulated body fluid (SBF), calcium growth was observed for both structures. Notably, MC3T3-E1 pre-osteoblastic cells grew on disks made up the alumina matrix coated with HAp and cell proliferation enhancements were similar to pure hydroxyapatite. These results suggest that structure is potentially useful as an artificial bone material.
