When preparing extrusion dies for nitriding, surface preparation is key.
Among the available methods (grinding, dry blasting, polishing), wet blasting stands out as the most effective technique. Here’s why:
✅ Produces a controlled, uniform roughness ideal for nitrogen diffusion
✅ Thoroughly cleans the surface, reducing contamination risks
✅ Gentle on the die - no micro-cracks or thermal stress
✅ Prevents abrasive embedment, unlike dry blasting
✅ Better nitriding results - improved hardness, wear resistance, and tool life
