Projects

Stellite, a cobalt-chromium superalloy with applications in aerospace, automotive, and biomedical industries, presents machining hurdles due to its formidable hardness, toughness, work hardening, and limited thermal conductivity. Challenges include excessive tool wear, poor surface finish, and dimensional inaccuracies. Addressing these demands strategic solutions, including specialized tool materials, applying coolant flood in specific locations, speed and feed optimization, rigidity reinforcement, and automation. Conquering these challenges requires a nuanced grasp of Stellite's properties, ensuring the cost-effective manufacturing ...
In Metalaser Laboratory, we have pioneered a restoration process for damaged High-Pressure Turbine (HPT) blades in aero gas turbine engines. Leveraging Laser Directed Energy Deposition (L-DED), our method involves using a laser beam to forge a robust metallurgical bond between the machined surface of the damaged part and filler metal, adhering to on-the-shelf and new blade specifications. The process on the blades underwent rigorous testing through Finite Element Method (FEM), and the resulted microstructure of ...
