A toolmaker sends a 420 stainless plastic mold cavity for nitriding. The gas-nitride certificate documents a 540°C cycle at Kn 2.5. The plasma-nitride certificate documents 75% H₂ / 25% N₂, 500 V bias, 480°C, 18 hours, target compound layer ≤2 µm. Why is plasma the correct technical answer for this part?
