Summary: The feasibility of friction stir processing (FSP) on 1.5-mm-thick austenitic stainless steel cold spray coating deposited on 304L stainless steel substrate was tested using a tungsten carbide tool. The study showed that FSP treatment was able to achieve a greater depth than the coating thickness, resulting in material mixing at the coating-substrate interface and a modified microstructure in the stir zone. Further optimization of FSP parameters is needed to enhance process reliability and prevent coating failure.

Summary: An electro-Fenton system with magnetite coated stainless steel mesh as cathode was developed and tested for removing methylene blue in wastewater. By coating magnetite particles on the surface of the mesh, catalytic activation of in situ produced H2O2 was enhanced, leading to better degradation efficiency of methylene blue in neutral conditions compared to acidic conditions.

Summary: Additive manufacturing allows for the design of thermoplastic components with structural support, electrical conductivity, and heat generation modulated by mechanical deformation. However, the mechanisms and interplays governing material response at the microstructural level are still uncertain. In this study, we develop an experimental method to characterize conductive filaments from mechanical, electrical, and thermal perspectives, and propose a homogenization framework to analyze the microstructure. The framework considers viscoplasticity, electrical and thermal conduction, convection, heat generation through the Joule effect, and their interdependencies. After validation, the framework is applied to optimize fabrication requirements for desired properties in final products, such as stiffness, conductivity, and sensing capabilities of filaments.

Summary: The present study investigated the microstructure, oxidation behavior, and thermal stability of ER310 and ER446 weld overlay claddings deposited on AISI 316 stainless steel using the gas tungsten arc welding (GTAW) process. The results showed that ER310 produced a completely austenitic microstructure, while ER446 exhibited a ferritic-martensitic two-phase structure. Both weld overlay claddings exhibited good bonding and improved oxidation behavior on AISI 316.

Summary: The YSZ coating has excellent electrochemical and tribological properties in 3.5 wt% NaCl solution when applied to a 304 stainless steel substrate, exhibiting low corrosion current density and friction coefficient. The friction coefficient only changes under high potential, and the material volume loss increases linearly with potential.

Summary: This study investigated the performance of polymer-derived ceramic (PDC) coatings under different testing conditions. The results showed that the microstructural modifications induced by differential sintering of the glass filler particles had a significant influence on the coating's performance. The existence of internal porosity also improved the coating's thermal shock resistance.

Summary: Reclaiming kinetic energy from vibrating machines holds great promise for sustainable energy harvesting technologies. This research develops a conductive hydrogel with an electro-responsive polymeric network, which can be used for lightweight, miniaturized, and integrated high-frequency electrochemical devices. The hydrogel can quickly form a localized electrolyte layer under the influence of an applied voltage, allowing for rapid charge transport with an exceedingly high local charge density. The micro-capacitor based on this gel exhibits a record-high capacitance when the frequency of energy input reaches up to 104 Hz. Additionally, a prototype battery charger that harvests energy from a running car engine is demonstrated in this study. This research presents a feasible strategy for waste energy recycling using integrated electrochemical devices, opening a new avenue for ambient energy management.

Summary: This paper investigates the microstructure, composition, and properties of an Al0.25CoCrFeNiV high entropy alloy coating deposited on austenitic-grade stainless steel by laser cladding. The study reveals changes in the microstructure and hardness of the coating after laser cladding, with a decrease in the size of vanadium precipitates and a variation in hardness across the coating thickness. However, the coating adheres tightly to the substrate without any cracks or defects, indicating the potential of laser cladding for creating high entropy alloy coatings.
