A green vanadium-based formulation for the conversion of steel Open
The electroless deposition of a novel vanadium-based conversion coating (VCC) on carbon steel was investigated varying parameters as vanadium salt concentration, immersion time, bath pH and temperature. The novelty resides on the depositio…
Investigating the activation of passive metals by a combined in-situ AFM and Raman spectroscopy system: a focus on titanium Open
Understanding the main steps involved in the activation of passive metals is an extremely important subject in the mechanical and energy industry and generally in surface science. The titanium-H 2 SO 4 system is particularly useful for thi…

A Comprehensive Investigation on the Effects of Surface Finishing on the Resistance of Stainless Steel to Localized Corrosion Open
The present research investigates the influence of surface roughness imparted by cold surface finishing processes on the localized corrosion resistance of stainless steel. Five different alloys were studied: ferritic AISI 430, martensitic …
Addition of Organic Acids during PEO of Titanium in Alkaline Solution Open
This research study describes recent advances in understanding the effects of the addition of organic acids, such as acetic, lactic, citric and phytic acids, on the process of plasma electrolytic oxidation (PEO) on Ti using an alkaline bat…
Sealing of porous titanium oxides produced by plasma electrolytic oxidation Open
Plasma electrolytic oxidation is a powerful technique allowing the formation of ceramic coatings with a high degree of functionalization. Plasma–chemical interactions, resulting from the application of a high voltage in a conductive electr…
Unipolar plasma electrolytic oxidation: Waveform optimisation for corrosion resistance of commercially pure titanium Open
This study deals with the anodisation of titanium grade 2 in 0.5‐M sulphuric acid using a pulsed signal in a unipolar regime. The electrical parameters investigated are voltage, frequency and duty cycle. The use of duty cycles with a high …
