  5. Methods of Non-Destructive Testing • X-Ray Testing • Costly • Exposure • Limited Area • Limited Material • Time Consuming • Not Practical for 100% • CAT Scan Testing (Computerized Axial Tomagraphy) • Costly • Exposure • Limited Area • Limited Material • Time Consuming • Not Practical for 100%

  6. Methods of Non-Destructive Testing (Cont.) • Ultrasonic Testing • Ultra High Frequency • Highly Directional Sound Waves • Measures Thickness • Measures Substantial Internal Flaws • Analyzes Reflected Sound Wave Patterns • Eddy Current Testing • Electromagnetic Induction Principle • Measures Near Surface Cracks • Measures Thickness • Measures Metals and Composites

  7. Methods of Non-Destructive Testing (Cont.) • Phased Array Testing • Specialized Ultrasonic Testing • Sophisticated Multi-Element Transducer Array • Requires Powerful Software • Similar to Medical Ultrasound Images • Good Off-Line Testing

  8. Methods of Non-Destructive Testing (Cont.) • Corona Beam Testing (ERAT: Electron Resonance Analysis Technology) • Drawn Through Material • Frequency Imposed Electron Beam • Open Atmosphere • Safe Non-Harmful to Material or Operator • Accuracy to 0.5 Nanometer • Measures Molecular Structure • Measures Permeability and Porosity • Identifies Fissures • Tortuous Path Holes • Non-Catalyzed Material • 100% Testing Capability

  9. Laser Beam vs. Corona Beam Technology • ConverTec • Problem • Discovery • Technology • Funding • Awards • Publications • Patents

  10. Schematic of One Corona Beam Gun • Frequency Charge Beam • Beam is Drawn Through Test Material • Signal Frequency Changes are Digitized and Processed • 100% Real-Time Testing • Non-Destructive • Non-Contact
