Pyrographite Evaluation (IPG)

Laser-ultrasound monitoring of isotropic pyrographite (IPG) have been developed. Method allows to detect carbon black inclusions and anisotropic pyrographite inclusions (APG) in IPG.
 


Carbon black presence evidence in IPG:
  • Bottom echo delay
  • Dark lines on the optoacoustic image scan
  • Characteristic reflected pulses on optoacoustic track
 

 

APG Presence Evidence in IPG:
  • Light areas or light inclusions on the optoacoustic image scan
  • Characteristic positive reflected pulses on optoacoustic track
