Strength properties of porous permeable stomatological materials based on titanium

Passivation and oxygen ion implantation double surface treatment on porous NiTi shape memory alloys and its Ni suppression performance

“…The Young's modulus and strength of the porous NiTi SMAs can be adjusted by changing the characteristic pore parameters. Therefore, the porous NiTi SMAs exhibit better biocompatibility and biomechanical compatibility than the dense NiTi alloys [7,8], and these can make the patients heal up faster and avoid osteoporosis after implantation. However, the NiTi alloy contains a large portion of Ni element (more than 50 at.% Ni), which is harmful to the human body.…”
