| AUTOMATED COMPLEX OF TESTING OF THICKNESS OF TECHNOLOGICAL COATINGS OF LRE ELEMENTS
The problem of non-destructive testing (NDT) of thickness of technological coatings of liquid rocket engines (LRE) elements is considered. For its solution, it is proposed to use method of X-ray fluorescent analysis. Automated complex of testing of thickness of technological coating of elements, consisting of measuring X-ray emitter, digital spectrometric device and precision positioning system based on ball-screw drives with position check by laser triangulation sensors is developed. Results of approbation of complex for testing of thickness of technological coatings on real samples of LRE parts are presented.
Keywords: non-destructive testing, X-ray fluorescent analysis, thickness measurement, technological coating.
