VIM and VAR Processing
VIM and VAR Processing
VIM provides accurate alloying and melt control, while VAR supports secondary remelting and refinement for critical ingot applications.
The combined process route is relevant for producing cast-alloy ingots and feedstock for:
Relevant Materials
- Turbine blades
- Turbine vanes
- Rotor components
- Stator components
- Investment casting
- Forging and hot-working operations
VIGA-Produced MCrAlY Powders
VIGA-Produced MCrAlY Powders
MCrAlY and related nickel/cobalt powders are used as protective coating materials for components exposed to oxidation and hot-corrosion environments.
The powders can support HVOF, plasma spray, flame spray and other surface-engineering processes.
