Method of Cryogenic Quenching in the Surface Treatment of Aluminum Alloys

  • Technology Readiness Level: 4 ( Technology validated in lab )
  • Technology Validation: This technology has been validated through laboratory validation.

Abstract
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.
