Biomimetic coating of calcium phosphate apatite on the alkali-thermal pretreated TI6AL4V / Nurul Hazwani Hanib

A biomimetic technique has been explored in the production of a high biocompatibihty titanium (Ti) apatite-coated. To form this coated material, a pre-treatment on the Ti surface are required to achieve an active surface either chemically or thermally treated. Usually, Simulated Body Fluid (SBF) sol...
