Corrosion and materials for industry

Area bacheca: 290&

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
