MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133487 A) filed by Dr. Mahalingam College Of Engineering And Technology, Coimbatore, Tamil Nadu, on Dec. 30, 2025, for 'laser based metal deposition over titanium for implant structures.'
Inventor(s) include R. Vishnu Rameshkumar; Dr. K. Sakthivadivel; and Dr. D. Shanmugam.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a laser-based metal deposition technique for forming functional surface layers on titanium implant structures. Referring to, the system employs a focused laser beam to generate a localized molten pool on a titanium substrate, into which metallic or alloy powder is delivered in a controlled manner to produce a dense and metallurgically bonded coating. The laser-based deposition process enables precise control over coating thickness, composition, and microstructure, resulting in enhanced surface properties such as wear resistance, corrosion resistance, surface hardness, and biocompatibility, while preserving the bulk mechanical integrity of the titanium substrate. Using protective gas shielding cuts down on oxidation and makes sure that the deposition is free of defects. The proposed technique allows the development of consistent surface layers, which include compositionally graded as well as multi-layer coatings and able to be effectively applied to implants having intricate shapes and contours. The technique offers a robust as well scalable manufacturing process for fabricating the titanium implant components with the improved surface integrity, long term reliability and superior functional performance."
