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

TDMS files containing the acoustic emission data collected as part of the experiments for "Application of acoustic emission sensorisation to plasma spray deposition" paperEach 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.The data can be opened either in Python with the nptdms package or just with MATLAB<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>ExperimentsThe 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.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%.Each coating run is composed of several behaviour sections designed to capture specific dynamics in isolation for further study.Few seconds of just sensor noiseEquipment is turned onA single coating pass is made using only the plasma, no powderFour coating passes are made applying metal powderEquipment is turned offFew seconds of just sensor noiseRefer to the paper for graphs and more in depth information about the experiment setup.
