MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611052794 A) filed by Delhi Technological University, New Delhi, on April 25, for 'green thermochemical processing of ti64 alloy for advanced biomedical surface engineering.'
Inventor(s) include Dr. Fadia Ahmed Naji; Dr. Qasim Murtaza; Mr. Gulam Fareed; Dr. Ali Nawaz; and Dr. Md Dilshad Alam.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a green thermochemical processing method for Ti64 alloy aimed at enhancing biomedical surface performance through environmentally friendly chemical treatment. The methodology utilizes a combination of citric acid and hydrogen peroxide under controlled pH conditions followed by heat treatment and simulated mineralization to modify the alloy surface. The process enables formation of a uniform oxide layer and bioactive coating that improves mechanical properties, corrosion resistance, and surface wettability. Experimental evaluation demonstrates increased microhardness, reduced wear rate, improved hydrophilicity, and enhanced hemocompatibility with minimal red blood cell damage. The treated surface further promotes hydroxyapatite formation with a calcium to phosphorus ratio comparable to natural bone, supporting superior bioactivity. The invention offers a sustainable, safe, and efficient alternative to conventional hazardous chemical treatments, making it highly suitable for long term biomedical implant applications requiring improved durability, compatibility, and biological integration while ensuring consistent processing outcomes across varied operating conditions reliably."
