2024年11月19日 · A Non-Destructive technique (NDT) based on Active Thermography (AT) is proposed to correlate mechanical properties, process parameters and thermal response for High-Entropy Alloys (HEA) coatings. More in detail, the Pulsed technique is utilised to investigate thermal responses generated by different High-Entropy Alloys (HEA) coatings.

Active thermography is an advanced nondestructive testing procedure, which uses a thermographic measurement of a tested material thermal response after its external excitation. This principle can be used also for non-contact [ 1 ] infrared non-destructive testing (IRNDT) of …

2018年11月1日 · Active thermography (AT) integrates infrared imaging with external heating and has turned out to be an essential approach for non-destructive testing and evaluation (NDT&E) of structural integrity of materials due to its inherent merits such as non-contact, high speed, whole-field, qualitative and quantitative inspection capabilities [1], [2 ...

2015年7月1日 · We summarize the history, models and applications of Thermal NDT (TNDT). TNDT is an established technique in the aerospace and other high-tech industries. The evaluation of composites in aerospace is the most typical application of TNDT. IR thermography is a promising technique in determining anisotropic thermal properties.

voidsy is developing a novel system for non-destructive testing (NDT) based on active thermography. This next-generation quality control works 80% faster and more cost-effectively than current standard inspection methods.
