The Indian Institute of Technology-Madras (IIT-M) incubated deep-tech start-up Kapindra Precision Engineering has developed diamond coatings that could aid Indian scientists working on heat dissipation (thermal management), a major issue for hypersonic missiles during their re-entry into earth’s atmosphere where they experience destructive high temperatures (more than 2,400 Deg C).
The start-up came from technology developed at IIT Madras’ Nano Functional Materials Technology Centre (NFMTC) and Materials Science Research Center (MSRC) led by Prof M S Ramachandra Rao, Department of Physics, IIT-M. Kapindra Precision Engineering works on development and application of specialized coatings for components used in strategic products that demand extreme tribological performances to reduce friction, wear and promote heat dissipation at contacting surfaces, a release from IIT-M said on Monday.
High quality thin film coatings were required for UV and IR detection/sensing, underwater SONAR devices, surface acoustic wave devices, pressure sensors and actuators, among others.
Prof Ramachandra Rao said, “Stronger adhesion to tools and components is required to transmit larger loads and enhance coating/tool life. Currently this comes at a cost of functional performance in the form of higher friction and wear. So how can the coating adhesion to the substrate be improved, while ensuring required tribological performance of low friction and wear?--this is the problem we are trying to solve.”
