Application of acoustic emission sensorisation to plasma spray deposition (TDMS)

<p dir="ltr">TDMS files containing the acoustic emission data collected as part of the experiments for "Application of acoustic emission sensorisation to plasma spray deposition" paper</p><p dir="ltr">Each file contains 2 MHz data from four acoustic emission sensors recorded using a PXI system. The four sensors were positioned on the four corners of a rectangular stainless steel plate being coated with powdered titanium.</p><p dir="ltr">The data can be opened either in Python with the <a href="https://nptdms.readthedocs.io/en/stable/" rel="noreferrer" target="_blank">nptdms</a> package or just with MATLAB</p><p dir="ltr"><b>WARNING: The files have been compressed to between 5-15% of their original size. Combined the total size of the uncompressed files is 100+GB. Ensure you have enough space before uncompressing</b></p><h2>Experiments</h2><p dir="ltr">The files were recorded as part of a series of experiments where a metal plate was sensorised and the data recorded as it was being coated. Two plates were coated in total with different process parameters being used for each. Each plate had 6 designated sites organised as two rows of three that were coated with a specific set of parameters. The file names are organised by plate number and then site so for e.g. plate-1-1 refers to plate 1 and site 1.</p><p dir="ltr">For Plate 1, the gas pressure was varied. Sites 1-3 were coated with 50 mBar at 550A. Sites 4-6 were coated at 150 mBar at 550A. For plate 2, the gun current was varies. Site 1 was coated at 535A and each subsequent site had the gun current raised by 5A (i.e. 540, 545, 550 etc.). The gas pressure for Plate 2 was 50 mBar. For all the robot speed was 34%.</p><p dir="ltr">Each coating run is composed of several behaviour sections designed to capture specific dynamics in isolation for further study.</p><ol><li>Few seconds of just sensor noise</li><li>Equipment is turned on</li><li>A single coating pass is made using only the plasma, no powder</li><li>Four coating passes are made applying metal powder</li><li>Equipment is turned off</li><li>Few seconds of just sensor noise</li></ol><p dir="ltr">Refer to the paper for graphs and more in depth information about the experiment setup.</p>
