Effects of Process Parameters on Microstructure and Properties of In-situ synthesized WC-reinforced Ni-based Cladding Layer

open access: yesMaterials Research
A novel tungsten carbide (WC)-reinforced nickel (Ni)-based laser cladding layer was prepared through an in-situ synthesis process. The mechanism of the effect of scanning rates and laser power on the microstructures, wear and corrosion resistance of in ...

Influence of laser shock peening on the joint surface strength of laser cladding repair of GH4169 superalloy component [PDF]

open access: yesMATEC Web of Conferences
Laser cladding is an effective method to repair damaged aeroengine blades. However, the heat affected zone of laser cladding reduces the strength of the repaired component.

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Passive Mode-Locking of Monolithic InGaAs/AlGaAs Double Quantum Well Lasers at 42GHz Repetition Rate [PDF]

open access: yes, 1990
Pulse trains with a 42GHz repetition rate were generated by monolithic InGaAs/AlGaAs double quantum well lasers at a wavelength of 985 [angstroms]. The cavity was electrically divided into three regions, one providing gain and the other two providing ...

Magnetic Textiles: A Review of Materials, Fabrication, Properties, and Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Magnetic textiles (M‐textiles) are emerging as a programmable materials platform that merges magnetic matter with hierarchical textile structures. This article consolidates magnetic material classes, textile architectures, and fabrication and magnetization strategies, revealing structure–property–function relationships that govern magneto‐mechanical ...

Photochromic Diarylethene‐doped SU‐8 for Rewritable Optics and Integrated Photonic Switching

open access: yesAdvanced Optical Materials, EarlyView.
A CMOS‐compatible photochromic host–guest material platform is realized by incorporating diarylethene molecules into SU‐8 photoresist. Reversible photoisomerization enables light‐programmable optical absorption, allowing rewritable optical patterning and port‐selective attenuation in integrated waveguides.
