Corrosion

• Corrosion rate (weight loss, electrochemical tests, LPR, potentiodynamic polarization curves, potentiostatic and galvanostatic tests, EIS)
• Evaluation of the resistance to localized corrosion by pitting e crevice, according to ASTM, ISO and NACE standards and by means of electrochemical tests
• Tests for evaluating resistance to Stress Corrosion Cracking (SCC) (constant load and strain and SSR tests)
• LEFM tests (CT, WOL, DCB)
• Tests for evaluating crack growth rate by corrosion-fatigue.

Mechanical tests

• Hardness tests and microhardness tests
• Tensile tests according to UNI, ISO and ASTM standards
• Fatigue tests (low and high frequency) under tensile/compressive or tensile loading with defined wave shape (sinusoidal, square wave, triangular, ...) under displacement, strain and load control
• LEFM tests (evaluation of KIC, da/dN)
• Elastoplastic Fracture Mechanics tests to study ductile materials (SENB, J/da curve, Jc and crack growth rate).
• Evaluation of thoughness by Charpy impact test
• Full scale tests on mechanical components
