TRDTRD (Thermo-Reactive Diffusion)

Our TRD process uses a vanadium carbide layer measuring .0001 to .0008 inches thick with a hardness of 3,200 to 3,800 Vickers that greatly increases the life of forming and shearing tools.

Applications for TRD include the following:

  •  metal stamping (particularly high strength materials)
  •  tube forming
  •  roll forming 
  •  cutting 
  • TRD die casting 
  •  extrusion 
  •  molding 
  •  shearing 
  •  forging
  •  machine components

TRD is a high temperature, thermal-diffusion process. The carbide layer is formed, or diffused, while the details/tools are immersed in a salt bath furnace that is heated to approximately 1,925 degrees. What results is a very thin, very hard surface treatment that is ideal for severe working conditions.

TRDBenefits of using TRD treatment include:

  •  hardness
  •  wear resistance
  •  friction resistance
  •  spalling resistance
