Simple low cost processing of metallic foam for diverse applications – Kausik Kapat, Indian Institute of Technology Kharagpur
Our innovation deals with a novel processing of metallic foam, which competes with the conventional techniques (melting, other powder metallurgical routes, additive manufacturing) in terms of simplicity, less energy consumption, reactive metal processing at reduced cost. This platform technology is useful for forming porous metallic structures and composites in defence, aerospace, automobile and biomedical application.
Using this technology, we have developed a highly open porous, light-weight titanium foam for healing critical bone fracture. The foam was further chemically modified for selective interaction with stem cells towards rapid bone formation. Rapid bone in-growth into the titanium foam eliminates requirements of bone cements for fixing of the implants to bone and resolves issues like post-implantation loosening via rigid and permanent fixation with bone. Finally, this reduces overall cost of therapy (20-40%) for the end users.
Low cost, rapid healing (2-3 months) of critical bone fracture through bioactive titanium foam without post-surgical complications
