SURFACE ANALYSIS LABORATORY

The surface analysis laboratory ensures the characterization of processes and structures obtained through Surface Electrochemical Engineering Methods under different experimental conditions, by correlating the results obtained through ESCA, EIS, DRX and LAXRD analysis,metallographic microscopy, ellipsometry, SEM, AFM.


Activities

  • Microphysical characterization of surfaces and thin surfaces (XPS analysis, XPS Microscopy, „depth profiling”);
  • Electrochemical surface engineering experiments (treatments on plasma electrolysis, electrodeposition from ionic liquids) for the development of materials for extreme conditions use - pressure, temperature and high neutron fluxes;

Certifications

  • The laboratory is designated as  Notified testing laboratory,  for SAXPS techniques (Small Area XPS), Microscopie XPS (fast Paralell imaging XPS) and „depth profiling”, according to Notification LI 02/2011 issued by the National Commission for Nuclear Activities Control (CNCAN);
