Corrosion Testing Laboratory – HF, Fluorine, Acid & Gaseous Tests
An expertise dedicated to demanding sectors: chemicals, energy, pharmaceuticals, aerospace…
SUDFLUOR supports manufacturers in the qualification and selection of materials subjected to severe chemical environments. In the laboratory, we reproduce extreme operating conditions in order to anticipate degradation phenomena and optimize the choice of materials in the design and operating phases.
Hydrofluoric Acid (HF) Corrosion Testing
Hydrofluoric acid (HF) is one of the most aggressive chemicals used in industry. Its combination of high acidity and fluoride reactivity can lead to rapid surface degradation, pitting, and formation of fluoride layers on metals, alloys, and fluoropolymers.
At SUDFLUOR, our HF corrosion tests are designed to replicate real industrial conditions, measuring corrosion rates, analyzing surface damage, and verifying post-exposure material integrity. Our laboratory evaluates metals, nickel-based alloys, high-performance fluoropolymers, and protective coatings to ensure reliability in critical applications. These HF corrosion tests allow manufacturers to select materials that maintain both performance and safety under harsh chemical exposure.
Beyond HF, many industrial processes expose materials to acidic environments that can dramatically reduce lifespan. Our laboratory evaluates materials in hydrochloric, sulfuric, nitric, and phosphoric acids, as well as in organic acid solutions when needed. By simulating process-specific conditions, we help clients anticipate corrosion phenomena, validate material selection, and ensure long-term operational safety.
Materials exposed to reactive gases require careful evaluation to guarantee durability and safety. At SUDFLUOR, we test materials in aggressive gaseous environments such as fluorine, chlorine, oxygen-rich atmospheres, and other reactive industrial gases. Each experiment is conducted under tightly controlled temperature, pressure, and exposure durations to closely replicate real operating conditions. These tests allow manufacturers to select materials capable of maintaining performance and integrity under severe chemical stress.
Our speciality
Fluorine Corrosion Testing: Evaluating Material Resistance to Fluorine Exposure
Fluorine corrosion testing is a critical method for assessing a material’s ability to withstand the highly aggressive effects of fluorine, one of the most reactive chemical elements. These tests are essential for industries in which materials are exposed to fluorine-rich and corrosive environments, including aerospace, nuclear, and microelectronics applications.
Why perform fluorine corrosion testing?
-
High-risk industries: Aerospace, nuclear, and microelectronics sectors require materials capable of maintaining performance and safety under severe fluorine exposure.
-
Development of new materials: Advanced alloys, composites, and engineered materials must undergo rigorous testing to validate their resistance to fluorine-induced degradation.
-
Protective coatings validation: As fluorinated and fluoride-based coatings become more widely used, evaluating their effectiveness in extreme chemical environments is crucial.
Key parameters evaluated
-
-
Corrosion rate: Quantifies material loss over time, providing insight into degradation speed in fluorine-rich conditions.
-
Formation of corrosion products: Identifies chemical compounds formed on the surface after exposure, which may affect material integrity.
-
Microstructural changes: Examines alterations in the material’s internal structure that can compromise mechanical and chemical durability.
-
Coating adhesion: Assesses the bonding strength of fluoride-based protective coatings to ensure long-term protective performance.
