“…The anodized samples also exhibited higher E pit values than the plain sample, indicating that the former samples are less likely to experience localized corrosion than the latter. The passive stability region (E pit -E corr ) was also expectedly larger for the anodized samples than the plain sample, demonstrating that anodization enhances passivation behavior [ 32 ]. Interestingly, the case of the heat-treated anodized sample showed a lower E pit than that of anodized welded SS, which can be attributed to the fact that a small amount of carbides was generated because the heat treatment temperature slightly spans the carbide formation temperature range.…”

“…Recently, a few studies were carried out to enhance the corrosion resistance of SS without utilizing the aforementioned methods. In one study [ 31 ], polypyrrole (PPA)-based coating containing polydapamine functionalized carbon powder (C-PDA) was applied, while, in another study [ 32 ], graphene oxide (GO) coating was applied. These studies provided great insight into how coating could be used to enhance the corrosion resistance of SS.…”

In this study, we fabricated a nanoporous oxide layer by anodization to improve corrosion resistance of type 304 stainless steel (SS) gas tungsten arc weld (GTAW). Subsequent heat treatment was performed to eliminate any existing fluorine in the nanoporous oxide layer. Uniform structures and compositions were analyzed with field emission scanning electron microscope (FESEM) and X-ray diffractometer (XRD) measurements. The corrosion resistance of the treated SS was evaluated by applying a potentiodynamic polarization (PDP) technique and electrochemical impedance spectroscopy (EIS). Surface morphologies of welded SS with and without treatment were examined to compare their corrosion behaviors. All results indicate that corrosion resistance was enhanced, making the treatment process highly promising.

Flexible transparent portable electronic products provide substantial support for the rapid development of the intelligent era. Flexible transparent supercapacitors (FTSCs) are considered the most promising energy storage devices due to their exceptional electrochemical performance, outstanding mechanical flexibility, and high optical transmittance. However, it is difficult to balance their mechanical flexibility and optical transmittance. The key to reconciling the contradiction is to fabricate flexible transparent conductive electrodes (FTCEs) with excellent mechanical flexibility and optical transmittance by combining the characteristics of manufacturing technologies and electrode materials. In this review, the characteristics of advanced FTCEs manufacturing technologies and their applications in FTSCs are systematically summarized. First, the device structure, working mechanism, and basic performance of FTSCs are briefly introduced. Second, the manufacturing characteristic and principle of different FTCEs preparation technologies are mainly described, including vacuum filtration, coating, deposition, printing, and layer‐by‐layer assembly. Next, the device structure and design principle of multifunctional FTSCs are demonstrated in detail. Finally, the challenges and prospects of applying FTCEs manufacturing technology to construct FTSCs are proposed.

“…The characteristic peaks of bioglass in the 1BG/GE/PCL composite were negligible in the XRD patterns due to the low amount of bioglass in the structure and it probably being in the amorphous state. Some additional peaks were observed at around 2θ equal to 43.5 • , 50.7 • and 74.7 • due to the presence of 316L SS substrate (JCPDS card number 33-0397) [41]. By increasing the bioglass content in the coating, the intensity of the SS XRD peaks decreased due to the formation of a thicker coating on the substrate.…”

In this study, various composites of bioglass/gelatin/polycaprolactone (BG/GE/PCL) were produced and coated on the surface of 316L stainless steel (SS) to improve its bioactivity. X-ray diffractometry (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) were utilized to characterize the specimens. The results showed that bioglass particles were distributed uniformly in the coating. By increasing the wt.% of bioglass in the nanocomposite coatings, the surface roughness and adhesion strength increased. The corrosion behavior of GE/PCL (PCL-10 wt.% gelatin coated on 316L SS) and 3BG/GE/PCL (GE/PCL including 3 wt.% bioglass coated on 316L SS) samples were studied in PBS solution. The results demonstrated that 3BG/GE/PCL sample improved the corrosion resistance drastically compared to the GE/PCL specimen. In vitro bioactivity of samples was examined after soaking the specimens for 7, 14 and 28 days in simulated body fluid (SBF). The results showed a significant apatite formation on the surface of 3BG/GE/PCL samples. The cell viability evaluation was performed using 3- (4, 5-dimethylthiazol-2-yl)-2,5 diphenyltetrazoliumbromide (MTT) tests which confirmed the enhanced cell viability on the surface of 3BG/GE/PCL samples. The in vivo behavior of specimens illustrated no toxicity and inflammatory response and was in a good agreement with the results obtained from the in vitro test.
