Název v původním jazyce

Non-destructive method for detecting damage of thermally sprayed samples under high-cycle loading

Popis výsledku v původním jazyce

The aim of the work was to design and validate a method of non-destructive testing of 3D printed thermal sprayed steel specimens subjected to vibration loading with a number of cycles greater than106. PCRT method was used as a starting point (Process Compensated Resonance Testing), which is used to test large sets of identical samples. PCRT is an advanced testing technique that uses acoustic resonance to determine variations in properties without destroying the sample. Due to its ability to provide accurate and repeatable results, this method is increasingly preferred in multiple industries, including aerospace, automotive, and composites manufacturing.In this report, we focus on evaluating the performance and reliability of the Process Compensated Resonance Testing (PCRT) method in testing 3D printed samples with and without thermal sprayed layer.The validation of the method was carried out in the following steps:I. Determination of the initial state of the sample (eigenfrequency distribution, Chapter 1),II. Cyclic bending loading of the specimen (Chapter 3),III. Determination of the sample state after loading (natural frequency distribution, Chapter 1). If the data comparison (Chapter 2) of Steps I and III does not indicate sample damage, proceed to Step II, otherwise the sample is sent to the materials laboratory for confirmation of sample condition.
