Porosity reduction model in titanium hydroxyapatite FGM composites using shrinkage measurement

A multilayered titanium (Ti)-hydroxyapatite (HA) functionally graded material was produced via pressureless sintering at 1100 degrees C. The initial and final porosities were determined via shrinkage measurements. The final porosity verification was carried out by the Archimedes method. The experime...
