“…Therefore, various factors contributed to the wear of Ni-W/TiN nanocomposites. First, the amount of TiN in the coatings had a significant impact on the wear resistance of Ni-W/TiN nanocomposites [27]. Dense TiN nanoparticles were incorporated into the metal matrix in Ni-W/TiN nanocomposites, resulting in nanocomposites with robust and stable structure.…”

This paper describes the pulse current electrodeposition (PCE) mediated preparation of Ni-W/TiN nanocomposites. Pulse current electrodeposition (PCE) was used to make Ni-W/TiN nanocomposites. The nanoindentation, wear, and corrosion of deposited Ni-W/TiN nanocomposites were studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The influence of pulse frequency (PF) and duty ratio on the shape, structure, phase structure, wear, and corrosion resistance of Ni-W/TiN nanocomposites was studied. When the duty cycle (DC) was 10%, the results demonstrated that a considerable number of fine grains were present on the deposited Ni-W/TiN nanocomposites, forming smooth, uniform, and fine organization. Increasing DC decreased the content of TiN nanoparticles in Ni-W/TiN nanocomposites. The content of TiN nanoparticles reduced from 11.3 wt % to 7.3 wt % by increasing the DC from 10% to 50%. In contrast, as the PF was increased, the TiN content in Ni-W/TiN nanocomposites increased. When the PF was increased from 50 Hz to 150 Hz, the TiN content increased from 6.4 wt % to 9.6 wt %, respectively. Furthermore, with a PF of 150 Hz and a DC of 10%, the produced Ni-W/TiN nanocomposites had an average hardness of 934.3 HV with ~39.8 µm of an average thickness. The weight loss of the Ni-W/TiN nanocomposites was just 17.2 mg at a PF of 150 Hz, demonstrating the excellent wear resistance potential. Meanwhile, the greatest impedance was found in Ni-W/TiN nanocomposites made with a DC of 10% and a PF of 150 Hz, indicating the best corrosion resistance.

“…The plating solution was adjusted to a pH of 4.7 by adding either sodium hydroxide (12 wt.%) or hydrochloric acid (15 vol.%), and the plating time was set to 40 min. The plating time was determined based on our previous study [7]. Scanning electron microscopy (SEM, S3400, Hitachi High-Tech Co., LTD., Tokyo, Japan) and IE-300X type energy dispersive spectroscopy (EDS) were used to study the morphological structures and cross-sections of the prepared Ni/TiN-SiC nanocomposites.…”

“…Hence, an excellent coating material can be used to cover the surface of sports equipment to prevent sports injuries and improve the durability of the equipment [4][5][6]. Nickel-based ceramic nanoparticle coating (NBCNC), a nanomaterial for enhancing the wear and corrosion resistance of sports equipment, is one of the most suitable and protective composite coatings for this equipment [7]. NBCNC also exhibited a high level of slip resistance, which is advantageous in decreasing sports injuries caused by hand slipping.…”

Sports are becoming an important part of everyday life. In this study, an excellent Ni-SiC nanocomposite was prepared on the dumbbell surface using the pulse electrodeposition (PE) method to improve the durability of sports equipment and prevent sports injuries. Transmission electron microscopy (TEM), scanning electron microscopy (SEM), abrasion testing, triboindentry, and X-ray diffraction (XRD) were used to evaluate the impact of plating conditions upon the microhardness, microstructure, morphology, and wear behavior of the fabricated coatings. The obtained results showed that several SiC and TiN nanoparticles were incorporated into Ni/TiN-SiC nanocomposites obtained at 4 A/dm2. SiC and TiN nanoparticles had mean diameters of 37.5 and 45.6 nm, respectively. The Ni/TiN-SiC nanocomposite produced at 4 A/dm2 showed an excellent mean microhardness value of 848.5 HV, compared to the nanocomposites produced at 2 and 6 A/dm2. The rate of wear for Ni/TiN-SiC nanocomposite produced at 4 A/dm2 was 13.8 mg/min, demonstrating outstanding wearing resistance. Hence, it has been suggested that the Ni/TiN-SiC nanocomposite can effectively reduce sports injuries.

“…Electrostatic spray deposition (ESD) uses high pressure to crack the polymer solution into fine droplets that adsorb to the substrate surface using a strong electric field to obtain uniform and smooth coatings. This method sees broad utilization in machinery, chemical industry, electronic information, micro medical devices, medical information, and others [13][14][15]. Olga et al [16] applied PLGA to drug-eluting stent coatings and found that PLGA effectively inhibited the growth of granulation tissue.…”

PLGA (Poly lactic-co-glycolic acid) and PLGA drug-loading coatings were prepared on 316 L stainless steel by electrostatic spray deposition (ESD). The surface morphology, three-dimensional morphology, and crystal structures of the coatings were observed by scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray diffraction (XRD). Thermal properties, molecular weight, and coating composition were studied by differential scanning calorimetry (DSC), gel permeation chromatography (GPC), and NMR. The degradation behaviors of the coatings were studied by mass changes, relative molecular mass and distributions, polymer compositions, thermal properties, and surface morphologies. The blood compatibilities of the coatings were investigated by platelet adhesion testing and dynamic coagulation times. SEM results indicated the drug-loading coating with 33% RAPA had the smoothest and most compact morphology. Addition of RAPA decreased the Tg of the PLGA coating, accompanied by partial crystallization that slowed the degradation rate of the drug-loaded coating. Microscopically, the morphology of the PLGA drug-loaded coating was coarser than the PLGA coating. The average surface roughness values of line and surface scannings were 16.232 nm and 39.538 nm, respectively. The surface of the drug-loading coating was micro uneven, and the macro smooth and micro multiphase separation structure helped improve its blood compatibility.
