Abstract
A porous titanium coating on titanium is fabricated by cold spraying "Mg + Ti" powders followed by vacuum sintering. The porous coating is interconnected, possesses the porosity of 48.6% with pore sizes in the range of 70-150 μm, and firmly bonds to titanium substrate with a bond strength higher than 42 MPa. The bending Young's modulus and bending strength of the porous coating are 14.47 ± 1.21 GPa and 106.93 ± 10.79 MPa, respectively. The compressive Young's modulus and compressive yield strength of the porous coating are 3.99 ± 0.12 GPa and 178.66 ± 13.20 MPa, respectively. The porous titanium coating has sufficient strength and matched Young's modulus with nature natural bone for clinical use under load bearing conditions.
