Enhanced Surface Properties and In Vitro Corrosion Tests of Ti─Nb─Sn Coating on CoCrMo Alloy for Biomedical Applications

Plasma Processes and Polymers, Volume 23, Issue 4, April 2026.
Ti–Nb–Sn thin films were deposited on CoCrMo alloy by DC magnetron sputtering to enhance surface performance for biomedical applications. The coating significantly improved corrosion resistance in PBS by reducing corrosion current density and increasing polarization resistance. Tribological tests under dry and PBS conditions revealed a marked reduction

Titanium migration and bone response in loaded osseointegrated implants: ESEM‐EDX analysis in Macaca fascicularis

Journal of Periodontology, Volume 97, Issue 3, Page 527-539, March 2026.
Abstract Background Titanium nanoparticle (TP) migration into peri‐implant bone may influence osseointegration. It remains unclear how loading protocols may affect TP distribution. This study aimed to detect TP in the bone around implants undergoing different loading protocols in Macaca fascicularis.

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.

Comparative study on dry wear and tribocorrosion behavior of boronized martensitic stainless steels

Fracture and Structural Integrity
The tribocorrosion behavior of boronized 13Cr4Ni and 16Cr5Ni martensitic stainless steels (MSS) in 3.5 weight percent NaCl is examined in this work. Samples were tempered at 600 °C for two hours and boronized at 950 and 1000°C for six hours.
