In harsh and corrosive industrial environments, steel parts and equipment can degrade rapidly,
leading to reduced performance, shorter lifespan, and increased repair or replacement costs
[1]. To address this issue, functional coatings can be applied to provide protection against
corrosion and fatigue [2-6], resulting in prolonged lifespan, reduced material waste, and
improved resource economy. In this study, the effectiveness of three types of functional
coatings applied via thermal spraying to carbon steel was evaluated. The first coating was a
nickel-based commercial corrosion-resistant metallic alloy powder called Diamalloy, the
second was WOKA powder, and the third was Alumina powder. The coated specimens were
sealed to reduce porosity and further functionalized through gas phase deposition of
trichloro(1H,1H,2H,2H-perfluorooctyl) silane as described previously [7]. Electrochemical
measurements, and contact angle studies were then conducted to assess the coatings'
effectiveness under harsh corrosive conditions with sulfates present.
