“…In addition to the focus on designing appropriate curing agent, also proposed the use of nano-silica (NS) to improve the weakness of organic materials. According to the previous report, the NS particles uniformly distributed in the epoxy resin can improve the mechanical, thermal stability, and abrasion resistance of the polymer matrix which probably enhances the anti-sliding durability of AS layer [23][24][25]. Thus, our results show that the combination of these design concepts leads to form a new epoxy-based composite material with a strong potential to serve the application of anti-sliding.…”

The anti-slip (AS) layer of the cement concrete pavement (CCP) can probability decrease traffic accidents and extend the service life of the road. Epoxy resin has excellent adhesion and mechanical strength, making it possible in this field. Herein, a flexible waterborne epoxy resin (WER) without a small molecule emulsifier was synthesized by bisphenol A epoxy resin, poly (propylene glycol) diglycidyl ether (PDE), diethylenetriamine (DETA). The mechanism of the group reaction was characterized by fourier transform infrared (FTIR), and dynamic scanning calorimetry (DSC) determined the heat of curing of WER. Then, the physical properties of WER were enhanced by the silane coupling agent modified nano-silica (SCA-NS) and the composite's water absorption rate and mechanical propriety were evaluated. Finally, the pavement performance of the AS layer was prepared and tested as well as compared with the commercial waterborne epoxy resin (CWER) and emulsified asphalt (EA). The result shows EA has low durability and adhesion strength than epoxy resin. The small molecule emulsifier and low-flexible resistance of CWER decrease water stability and antisliding durability of the AS layer. Due to applied nanomaterial reinforced and without small molecule emulsifiers, the WER base AS layer shows extremely high adhesion strength, water stability, and skidresistance durability at addition 3 wt% of SCA-NS, which have a great potential for CCP.

The focus of this work was to analyze the effect of weight percentage (wt%) of Polyalthia longigolia seed filler (PLSF) on the wear responses (wear loss and coefficient of friction) of the vinyl ester (VE) matrix composites, using signal‐to‐noise (SN) ratio and analysis of variance (ANOVA) methods. The Polyalthia longigolia seed filler/vinyl ester (PLSF‐VE) composites were produced by compression molding (CM) technique. Scanning electron microscopy (SEM) analysis showed that the PLSF content was homogeneously distributed in the matrix. Pin on disc (POD) wear tester was employed to carry out the experiments. Both SN ratio and ANOVA were performed to determine the process parameters that exhibited lower wear responses. The wear of the composite was minimized by optimizing the four diverse process factors: load, P (N), sliding speed, N (rpm) and filler content (wt%), based on Taguchi's L9 orthogonal array. The process parameters at which minimum wear loss (WL) occurred were identified with 25 wt% sample at 10 N and 300 rpm. Also, the process parameters for minimum coefficient of friction (COF) were observed with 25 wt% sample at 5 N and 700 rpm. From the ANOVA results obtained, it was evident that P mostly influenced the WL and COF of the PLSF‐VE composites during POD wear testing. This kind of lightweight composite can be a suitable alternative for small scales loading conditions, such as brake bad and clutch plates in the automobile industry.

“…Nano-SiO 2 has low costs, excellent wear resistance and chemical inertia, and is also often used as an additive for MAO and other coatings. For example, when nano-SiO 2 is added to a MAO coating on the surface of a 7A52 Aluminum alloy, experimental results show that it can improve the wear resistance and corrosion resistance of the MAO coating [ 14 ]. At present, there are relatively few studies on the effects of nano-SiO 2 on the corrosion resistance of magnesium alloy MAO coatings.…”

In order to improve the corrosion resistance of the automotive AM60B-Mg alloy, a nano-SiO2/MAO composite coating was prepared on the surface of the alloy. The electrochemical properties were studied in an 80 °C corrosion environment using potentiodynamic polarization tests. Local Electrochemical Impedance Spectroscopy (LEIS) was used to study the corrosion mechanisms of coating defect zone. The microstructure and phase of the samples were observed by confocal laser microscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD). Macroscopic electrochemical test results showed that the impedance of the nano-SiO2/MAO coating was much higher than that of the MAO coating, by about 433 times. Local electrochemical test results showed that the minimum impedance of the nano-SiO2/MAO coating was 1–2 orders of magnitude higher than the maximum impedance of the MAO coating. The defective SiO2/MAO coating still had high corrosion resistance compared to the defective MAO coating. A physical model of local corrosion mechanisms was proposed.
