The Corrosion Department performs testing and evaluation of the corrosion performance of functional surfaces to support the clients in new developments, current product/process improvements or products quality assurance. The corrosion mechanism associated with functional surface behavior during testing or service is studied and the critical to corrosion quality characteristics of the products are determined. Corrosion behavior of bare metals or various surface treatments including cleaning and chemical, electro-chemical or polymer-based coatings is examined following international standards or customers specifications. Various testing methods based on samples immersion or exposure in special chambers at artificial corrosive environments are used.
Typical evaluation methods include:
Macro/micro-scopic appearance (Stereo/LOM/SEM),
Creep corrosion; ΙSO 4628-8,
Blistering; ΙSO 4628-2,
Pitting Corrosion; ASTM G46:94,
Corrosion Rate; ASTM G1-03,
Chalking; EN 13523-14,
Gloss; EN 13523-2,
Colour difference; EN 13523-3.
