Frequently Asked Questions
How to choose appropriate characterization method?
Choose based on information needed: SEM for interface morphology, TEM for atomic structure, EDS for composition distribution, peel testing for bond strength, four-point probe for conductivity. Combining multiple methods provides comprehensive characterization.
What are the limitations of non-destructive testing?
Ultrasonic testing has difficulty detecting small defects (<0.5mm); eddy current testing is affected by material magnetism and surface condition; X-ray testing has low sensitivity for thin sections. Non-destructive testing needs to be combined with destructive testing.
How to ensure accuracy of test results?
Methods to ensure accuracy: use calibrated equipment, follow standard test methods, perform repeat testing, establish test uncertainty assessment, regularly conduct inter-laboratory comparison. Testing personnel need professional training.
