Corrosion

Corrosion testing services

Comprehensive testing expertise

We can give advice and provide the following tests.

Materials selection testing for resistance to environment assisted cracking

  • Proof rings testing (NACE Standard TM0177)
  • C-ring testing (NACE Standard TM0177)
  • Four-point bend testing (NACE Standard TM0316)
  • Slow strain rate testing (NACE Standard TM0198)
  • Drop-evaporation testing for stress corrosion cracking
  • Hydrogen induced cracking testing (HIC)
  • Hydrogen permeation measurement for hydrogen uptake and diffusion rate

Evaluation of corrosion inhibitors

  • Small-scale flow loop
  • Multi-electrode underdeposit corrosion test capability

Crack growth rate measurement

  • High resolution crack growth monitoring system (accessing growth rates < 10-12 m s-1)
  • Crack growth in small and long crack regimes
  • Crack growth measurements in environmentally-controlled atmospheric conditions as well as under full immersion
  • Precisely controlled water chemistry with on-line monitoring
  • Stress corrosion and corrosion fatigue cracks

Pitting, crevice and intergranular corrosion evaluation

  • Galvanic corrosion testing
  • Pit size distribution analysis and pit profile characterisation
  • Critical pitting temperature and threshold water chemistry for pit initiation
  • Pitting and repassivation potential measurement
  • Impact of surface condition and inclusions for pit initiation
  • Analysis of single pit development
  • Pit-to-crack transition studies
  • Crevice assemblies
  • Electrochemical potentiodynamic reactivation test (electro-potential reactivation) for intergranular corrosion in sensitized alloys and for depleted zones associated with particles (including σ-phase in duplex stainless steel)

Key electrochemical and surface measurements

  • Potentiodynamic tests
  • Scanning electrochemical microscopy (SECM)
  • Electrochemical impedance spectroscopy (EIS)
  • Raman spectroscopy: structural and chemical analysis
  • Scanning electron microscopy (SEM)
  • Electron back-scatter diffraction (EBSD)
  • Optical and confocal (3D) microscopy

We also carry out complementary electrochemical measurements as well as materials imaging and characterisation.
