This study selected hard Al<sub>2</sub>O<sub>3</sub> and SiO<sub>2</sub> nanoparticles as strengthening phases and uniformly doped them into the Ni–P matrix using pulsed electrodeposition technology. The surface quality and mechanical properties of the composite coating were improved by optimizing the duty cycle parameters, and the effect of duty cycle on the deposition behaviour of the composite coating was revealed. The microstructure, composition, wear resistance and elastoplasticity of the composite coatings were characterized by scanning electron microscope, energy dispersive spectrometer, X-ray diffraction analyzer and nano-indentation instrument. The research results indicate that the reduction of pulse duty cycle has significant grain refinement and concentration polarization reduction effects, but this seriously sacrifices the deposition rate. Under direct current conditions, there are numerous defects such as pores and micro cracks on the surface of composite coatings. When the duty cycle is 40%, the surface of the composite coating is smooth and dense, and its micro hardness and elastic recovery ratio (<i>h</i><sub>e</sub>/<i>h</i><sub>max</sub>) reach their maximum values of 806 HV and 0.48, respectively, while the average friction coefficient reaches its minimum value of 0.27, which indicates that it has good mechanical properties. This study provides a theoretical basis for the efficient preparation of Ni–P–based composite coatings and improve its application value in surface engineering. </p></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"48 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, information on the effect of types of waveform on the quality of graphene nanoplatelets (NPs) is scanty. In this study, different types of waveform, namely direct current (DC), pulsed direct current (PDC) and bipolar waveform (BP) were used for the electrochemical exfoliation of graphite. All experiments were performed keeping other process parameters constant, such as electrolyte concentration (0.05 M KOH solution), temperature (303 K), distance between electrodes (6 cm) and stirring speed (200 rpm). It is observed that the type of waveform plays a significant effect on the defect concentration and size of the as-synthesized graphene NPs. The size of graphene NPs synthesized using PDC, BP and DC waveforms was in the range of 1–5, 60–220 and 250–450 nm, respectively. Raman spectroscopic analysis confirmed that multilayer graphene consisting of 4–5 layers of C atoms was successfully synthesized irrespective of the type of waveform.

The X-ray photoelectron spectroscopic (XPS) analysis showed that the highest C/O ratio (i.e., less oxygen) was noted in graphene synthesized using the PDC waveform.

In contrast to traditional synthesis methods, a single-step green method is demonstrated for reducing graphene oxide. A simple one-step hydrothermal method successfully synthesized reduced graphene oxide (rGO)-multi-walled carbon nanotube (MWCNT). The composite was characterized using X-ray diffraction (XRD), micro-Raman, scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX), fourier transform infrared spectroscopy (FTIR), UV-visible absorption spectroscopy (UV-Vis) and zeta potential measurements. The present work aims to investigate the feasibility of utilizing nonlinear optical properties of reduced graphene oxide-carbon nanotube (rGO-CNT) composite as an optical limiter. The Z-scan technique was used to study the composite nonlinear absorption properties at a laser intensity of 532 nm. The result displayed that the composite material exhibits strong nonlinear absorption properties, chiefly resulting from the synergistic impact of rGO and CNT. The optical limiting behaviour of the rGO-CNT composite was evaluated, and it demonstrated excellent performance with a limiting threshold of 0.70 × 10<sup>12</sup> W m<sup>–2</sup>. Combining MWCNT tubular shape, homogeneous decorating and strong visible absorption with rGO’s extensive conjugation for charge transfer leads to a highly improved nonlinear optical (NLO) response. The excellent optical limiting performance of rGO-CNT composite makes it an ideal candidate for laser safety and energy stabilizer devices operating in the 532 nm, 9 ns laser domain.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"48 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studies were carried out with a scanning electron microscope and X-ray photoelectron microscopy and indicated the occurrence of tribo-oxidative processes in the polymer/metal contact zone. The investigation of the elemental composition of the friction surface by energy dispersive analysis revealed the appearance of new peaks corresponding to Fe and Cr. This fact indicates the interaction of the counterbody metal with the polymer during friction. The occurrence of defluorination and hydroxylation reactions of PTFE macromolecules on the friction surface of PCM was recorded based on the results of X-ray photoelectron spectroscopy. A possible mechanism is proposed for the tribochemical processes that occur on the friction surface of composites, regardless of the composition of the fillers. It has been established that a protective layer is formed consisting of filler particles and tribodestruction products due to tribochemical reactions on the friction surface. The formation of a secondary layer is not observed in the case of a composite with phlogopite. Thus, the main factor in increasing the wear resistance of PTFE-based PCM is the formation of new secondary structures on the friction surface in the friction zone due to the occurrence of tribo-oxidative processes.
