Description
Uribe Cruz and four co-authors studied corrosion in a nickel alloy after plasma nitriding in twenty twenty-five. Inconel 718 serves in salty settings where resistance to localized corrosion matters. Nitriding hardens its surface, but the team asked whether the treatment also weakens corrosion defenses.
They treated the alloy at low temperature for two hours. The surface grew up to three times harder, with a thin hardened layer. Analysis confirmed chromium nitride particles formed in the layer. Standard corrosion tests showed little change in most measures, yet the corrosion rate doubled. The temperature at which pitting begins fell by over thirty degrees, dropping below ten degrees. The authors conclude the hardening gain comes at a real cost in chloride-rich settings.
