WORKING PRINCIPLE OF 

PHONON INSPECTION

The industrial facilities (such as pipelines, pressure vessels, etc.), rather the materials from which they are made, are influenced by effects of different types such as mechanical, thermal, magnetic, i.e. energy effects them from outside. 


The materials themselves have internal energy, including the energy of the crystal lattice bonds — phonon emission.


There is an interaction of material and energy going in a component under operating conditions, i.e. the energy ( E) supplied from the outside interacts with material ( M). 


As a result of this energy interaction, there are processes of redistribution, concentration and release (emission) of energy by the material i.e. phonon emission PhE is formed in the material and around it.


The universal reaction of interaction in terms of "material (structure) – energy" can be written as follows:  E + M = PhE


As a result of interaction between energy and material is various physical processes - corrosion damage, thinning, fatigue damage, and destruction. 


Phonon emissionis most intense and concentrated in places where corrosion, damage, defect formation and destruction are occurring.


Distribution, intensity, concentration and other parameters of phonon emission directly characterise the processes occurring in the structure, determine the state of the material, characterise the technical condition of the structure.


The most important part of Phonon Diagnostics Technique are the advanced software technologies. 


Among other things, detection of defects by Phonon Diagnostics Technology is based on the component topology in the process of data collection and processing.
