Pushpak Aerospace India Pvt. Ltd. has signed a Transfer of Technology (ToT) agreement with IN-SPACe–ISRO for the advanced anodization of 3D-printed Al-10Si-Mg alloy components. The process, developed by the U R Rao Satellite Centre (URSC-ISRO), is designed to support thermal treatment and satellite manufacturing industries. Pushpak Aerospace will establish a dedicated facility to deploy the technology.
The anodization process enables surface treatment of 3D-printed Al-10Si-Mg alloy, a material intended for spacecraft thermal control applications. It uses a mixture of sulphuric acid and oxalic acid electrolytes and can be applied in potentiostatic and galvanostatic modes.
According to the specifications, the anodic oxide coating provides high infrared emittance of at least 0.85 and solar absorptance of at least 0.90, aiding in temperature regulation and performance of satellite components.
Pushpak Aerospace stated that the new facility will deliver specialised processing capabilities for aerospace components and address gaps in the supply chain for satellite manufacturers. This technology enables the production of lightweight, durable parts for satellites and spacecraft.
Pushpak Aerospace India Pvt. Ltd. is engaged in electrochemical processing and has prior collaborations with ISRO and defence establishments. The company operates certified facilities and focuses on providing solutions for aerospace and related sectors.
