Comparison of Intergranular Corrosion Resistance and Hardness between Nitrogen and Carbon Martensites in Stainless Steels

steel research international, Volume 97, Issue 3, Page 1538-1546, March 2026.
By applying solution heat treatment after plasma nitriding, followed by requenching and tempering, researchers successfully obtained nitrogen‐rich martensite on AISI 409. This study compares the intergranular corrosion resistance and hardness of nitrogen‐rich martensite in AISI 409 with carbon‐rich martensite in AISI 420.

In Vivo Corrosion of Acetabular Modular Tapers Reduces Local Corrosion Resistance: Near‐Field Electrochemical Impedance Spectroscopy as an Indicator of the Type and Severity of Corrosion in Retrieved Hip Implants

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 1, January 2026.
ABSTRACT Retrieved hip implant components experience a range of corrosion types and severity, often on small surface areas of the taper region. Tribocorrosion‐related damage within modular taper regions and resulting changes of the oxide‐covered surface can alter the local impedance of the interface.

Advancements in Modelling the Tribocorrosion Current

ChemElectroChem
AbstractTribocorrosion in passive metals involves a complex and interactive mechanism between mechanical and electrochemical actions at a rubbing contact in a corrosive environment. The mechanical wear mechanism disrupts the passive film on the metal surface; and instantly, the metal repassivates and dissolves in the corrosive environment. This surface
