KW (Standard Nitriding)
Technical Analysis: Hardness, Composition, and Structure
KW Nitriding Treatment Data
Hardness Distribution Analysis
The graph demonstrates the hardness profile relative to the distance from the surface.
Surface Hardness: Achieves up to Hv 900–1000 (approx. HRC 67-70) depending on the steel grade.
* Effective Depth: Shows a gradual transition from the hard surface layer to the core material (Target HRC 48), ensuring excellent adhesion and toughness without peeling.
Surface Organization (EDS Analysis)
Energy Dispersive X-ray Spectroscopy (EDS) results confirm the precise chemical composition of the nitrided layer.
The analysis verifies the controlled diffusion of Nitrogen (N) into the ferrous matrix. * Treatment Condition: 350°C x 1Hr + 520°C x 8Hr.
Surface Structure Analysis (XRD)
X-Ray Diffraction (XRD) analysis reveals the crystalline phases present in the surface layer.
Identify the formation of beneficial nitrides such as Fe₃N and CrN.
These stable phases are responsible for the superior wear resistance and thermal stability of KW-treated molds.
