Mechanism of vertical crack formation in Yb2SiO5 coatings deposited via plasma spray-physical vapor deposition

Journal of Materiomics, 2020
Plasma spray-physical vapor deposition (i.e., PS-PVD) is a promising method for obtaining advanced environmental barrier coatings (EBCs). The EBCs must meet some requirements in the application, in which the thermal cycle performance affects the service ...

Crack-Resistance Behavior of an Encapsulated, Healing Agent Embedded Buffer Layer on Self-Healing Thermal Barrier Coatings [PDF]

, 2019
In this work, a novel thermal barrier coating (TBC) system is proposed that embeds silicon particles in coating as a crack-healing agent. The healing agent is encapsulated to avoid unintended reactions and premature oxidation.

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...
