Indian scientists repaired Aero-engine components for the first time through a 3D printing technique called ‘Directed Energy Deposition’ process which can significantly reduce repair costs and overhaul time. For the additive manufacturing process, they indigenously prepared the powders.
For them, Ni-based superalloys are widely used but despite having exceptional properties which are prone to damage due to extreme functioning conditions.
A media release said, "The team of scientists from the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) indigenously developed powders suitable for additive manufacturing using inert gas atomiser available at the ARCI by melting unused scrap material. Utilising this, the ARCI is developing the Laser-DED process for the repair of aero-engine components made of Ni-based superalloy."
A journal named Transactions of The Indian Institute of Metals published the work. The technology developed by the ARCI can be the best realised in the aerospace sector due to expensive materials, manufacturing costs, and stringent quality checks.
