Hydrogen embrittlement is a common, dangerous, and poorly understood cause of failure in many metal alloys. This article presents a model based on the correlation of mechanical properties to scanning electron microscopy fractography analysis of fracture surfaces in the presence of simultaneously active hydrogen embrittlement micro-mechanisms.

Microbial reduction of Cr(VI) in the presence of chromate conversion coating constituents – Publication
This article shows how biological electrochemical reactions can be used to bioremediate hexavalent chromate, i.e., Cr6+ or Cr(VI), waste waters in the presence of other potentially toxic species used in chromate conversion coatings.
Aluminum alloy corrosion inhibition by vanadates – Publication
This article solved the puzzle of vanadate speciation in aqueous solutions and its effect on aluminum alloy corrosion inhibition.
Use of the critical acidification model to estimate critical localized corrosion potentials of duplex stainless steels – Publication
Can we use Galvele’s critical acidification model to estimate the localized corrosion resistance of engineering stainless steels?
Short answer: yes; long answer: it is complicated.

Effect of Tungsten on the Pitting and Crevice Corrosion Resistance of Type 25Cr Super Duplex Stainless Steels – Publication
Are all super duplex stainless steels alike? Does tungsten additions have an influence on localized corrosion resistance?
Spoiler: it does, and it is remarkable.
Tribute to Professor José Rodolfo Galvele
The year 2016 marked the 40th anniversary of Prof. Galvele, critical acidification model. CORROSION Journal dedicated January’s issue (CORROSION Vol. 73 Issue no. 1) to honor Galvele’s legacy.
