Researchers at Purdue University have developed a method of cryogenic quenching in the surface treatment of aluminum alloys. This technique uses high cooling rates to allow for a surface hardness similar to that of a T6 temper without the need to heat the workpiece in a high temperature furnace. In addition to heat treatment, this method can also be used to cool the alloy following laser material deposition. This technology represents a step forward for the surface treatment of high hardness aluminum alloys.

Advantages:
- Similar hardness to a T6 temper
- Does not require a high temperature furnace
- Can be used for surface buildup via material deposition

Applications:
- Tempering aluminum alloys
- Laser cladding of aluminum alloys

Technology Validation:
This technology has been validated through laboratory validation.
