Acquired Properties Comparison of Solid Nitriding, Gas Nitriding and Plasma Nitriding in Tool Steels
TL;DR: In this paper, the acquired properties were compared and evaluated on these three processes with the aim to verify the solid nitriding performance, and the wear tracks were analyzed using SEM (Scanning Electron Microscopy).
