Knee Implant Parts By MIM Process
Jan 30, 2019

The slow progress of MIM technology in the field of human body implantation is mainly due to the long cycle of product certification and acceptance.

At present, the use of MIM technology can produce replacement part of bone and joint parts. The main metal material used is Ti alloy.

In terms of biocompatibility, Chen Liangjian prepared porous titanium with 60% porosity by MIM technology, and prepared gelatin sustained-release microspheres by improved condensation polymerization crosslinking method and coated on the surface of porous titanium.

The results showed that porous titanium coated with gelatin sustained-release microspheres had no cytotoxicity and could be used as a good material for medical implants.
