Nickel based high temperature alloy turbine

These blades utilize superalloys with nickel as the matrix, incorporating rare elements such as chromium, cobalt, and tantalum. They exhibit exceptional high-temperature strength, creep resistance, and corrosion resistance, presenting extremely high manufacturing barriers.

Recycling Value: Discarded turbine blades represent valuable “urban mines,” rich in strategic metals like nickel, cobalt, chromium, and tantalum, making them highly valuable for recycling. Recycling and reuse can conserve 40%-90% of energy, significantly reduce production costs, and safeguard critical mineral resources, delivering both economic and environmental benefits.

Recycling Technology: The high temperature alloy recycling process is technology-intensive. First, strict grade classification and removal of surface coatings are required. The core involves advanced techniques like Vacuum Induction Melting (VIM) or Electron Beam Cold Bed Refining (EBCHR) for remelting and refining. Conducted under vacuum or controlled atmospheres, these processes effectively eliminate impurity gases and inclusions while precisely controlling composition. This yields high-quality master alloy ingots suitable for manufacturing new components, achieving closed-loop resource utilization.
