Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Detecting Criticality by Exploring the Acoustic Activity in Terms of the “Natural-Time” Concept
Applied Sciences, 2021 The acoustic activity developed in marble specimens under various loading schemes is explored in terms of the recently introduced F-function. The novelty of the study is that instead of describing the temporal evolution of the F-function in terms of ...

Acoustic Emission Characteristics of Galling Behavior from Dry Scratch Tests at Slow Sliding Speed
AcousticsGalling wear, a severe form of wear, is a known problem in sheet metal forming. As the wear state is not directly observable in closed tribosystems, such as in industrial sheet metal forming processes, indirect tool wear monitoring techniques for ...

Deformation processes and emissions of acoustic impulses at the uniaxial loading of selected rocks from the Czech part of the Upper Silesian Basin [PDF]
Acta Montanistica Slovaca, 1998 The deformation and induced acoustic emission during uniaxial loading were studied. Three main phases were distinguished during the whole deformation process: the initial one, in which the adjustment of rock specimen to the loading frame occurred, the ...

Advanced Engineering Materials, EarlyView.Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.
