CONSIDERATIONS REGARDING CORROSION BEHAVIOR OF ALUMINUM ALLOYS PROCESSED BY FRICTION STIR PROCESSING (FSP) OR SUBMERGED FRICTION STIR PROCESSING (SFSP)

Nonconventional Technologies Review
Microstructural stability and submerged properties of aluminium alloys are critical to their integrity and service life in corrosive environments. Submerged friction stir processing (SFSP) and friction stir processing (FSP) have become effective methods

RESEARCH ON SUBMERGED FRICTION STIR PROCESSING OF EN AW 6082 ALUMINUM ALLOY

Nonconventional Technologies Review
Submerged friction stir processing (SFSP) is a variant of processing the surfaces of metallic materials that uses the liquid medium to ensure a process temperature that does not thermally overload the materials to be processed or the processing tool ...

Ductility Improvement of an AZ61 Magnesium Alloy through Two-Pass Submerged Friction Stir Processing. [PDF]

Materials (Basel), 2017
Friction stir processing (FSP) has been considered as a novel technique to refine the grain size and homogenize the microstructure of metallic materials. In this study, two-pass FSP was conducted under water to enhance the cooling rate during processing, and an AZ61 magnesium alloy with fine-grained and homogeneous microstructure was prepared through ...

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

Advanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

Root‐Inspired Microneedle Patch With Interlocked Rigid‐Soft Architecture for High Tissue‐Adaptiveness

Advanced Science, EarlyView.
A root‐inspired microneedle array patch uses lattice‐based mechanical interlocking to unite rigid microneedles with a flexible substrate. The interlocked rigid–soft architecture improves interfacial bonding, supports stable adhesion on curved and wet tissues under dynamic motion, and provides a versatile platform for robust biointerfacing and future ...

Self‐Responsive Plastron Maintenance on a Superhydrophobic Mesh via Locally Integrated Electrolysis

Advanced Science, EarlyView.
This work presents a self‐switchable SHM‐E surface that enables rapid, autonomous plastron self‐repair and long‐term stability. Plastron loss triggers circuit closure and localized electrolysis, while capillary spreading rapidly restores a continuous plastron and self‐terminates the current.

Effect of Submerged Multi-pass Friction Stir Process on the Mechanical and Microstructural Properties of Al7075 Alloy

Journal of Stress Analysis, 2017
The friction stir process (FSP) is a solid-state process which is used for severe plastic deformation of materials and modification in microstructure. The microstructure evolution, which iscaused by dynamic recrystallization, changes the mechanical properties of the material. In this study, the FSP of the surface of Al7075 alloy is carried out using 0%

Next Generation Antimicrobial Coatings for High Touch Surfaces: Application, Benefits, Risks, Environmental Impacts and Sustainability Aspects

Advanced Science, EarlyView.
Antimicrobial coatings for high touch surfaces promise infection control but are too often validated only in the lab. This review shows that active‐agent release governs both human toxicity and environmental impact and argues that durability and real‐world performance must be primary design criteria, placing a safe‐and‐sustainable‐by‐design framework ...
