Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced 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.

Assessing Damages in Pipes through Circular Distribution of Ultrasonic Guided Wave Reflections from Defects

open access: yesChemical Engineering Transactions, 2016
Damages in pipes such as cracks and corrosions may threaten the integrity of pipeline. Using ultrasonic guided waves to detect these defects is efficient. The waves propagate in the pipe wall and carry information of the entire structure.
