Dynamic Mechanical Strain-Induced Temperature Gradient Coating

Evaluating components for discontinuities without damaging the part or system remains a priority for diverse industries and research fields. Low-cost techniques such as fluorescent penetrant inspection (FPI) are used widely by major industries, such as aviation and aerospace, despite limited defect detection and the need for complex, multi-step operations in highly controlled conditions. Nondestructive methods such as sonic infrared (SIR) testing apply ultrasound waves to identify surface defects and cracks. These techniques hold promise for widespread use but stand to improve in the detection of false positives.
