Low-temperature Boriding of Lightweight Engine Materials

National Laboratory: 
Argonne National Laboratory
Characterization Class: 
Extreme Environment Testing
Mechanical Behavior of Materials
Processing/Manufacturing Class: 
Fabrication and synthesis
Description: 

ANL offers a breakthrough technology that enables boriding of aluminum, magnesium, and titanium alloys that are very thick and operates fast at temperatures of ~200°C using a proprietary molten salt electrolyte. This option affords the possibility of broadening lightweight materials uses to applications that involve actual engine components, such as pistons, cylinders, etc. Borided surfaces will resist wear, scuffing, corrosion, and high-temperature oxidation, as well as provide low friction. ANL has the most extensive expertise, facilities, and characterization tools that should quickly lead to substantial advances in new product/process development and implementation.

Capability Bounds: 

None

Unique Aspects: 

Argonne is the only national laboratory that offers boriding, infrastructures, expertise, and characterization/tribotesting capabilities.

Availability: 

Capabilities are readily available. Note: updates/upgrades to the boriding furnaces are made as needed.
