“…Typically, the lower the wettability of the coating, the higher the contact angle. [ 29,30 ] To explore the effect of AP as the binder on the surface wettability of the coating, contact angles of CBPCCs were measured. As shown in Figure 5, the contact angle of CBPCCs, ranked in descending order, is CBPCC3 > CBPCC4 > CBPCC2 > CBPCC1.…”

In this study, chemically bonded phosphate ceramic coatings (CBPCCs) with different contents of aluminum phosphate (AP) are prepared on stainless steel (AISI 304L). Differential scanning calorimetry, X‐ray diffraction, contact angle test, and a tribocorrosion experiment are carried out to clarify the role of AP in the tribocorrosion performance of CBPCCs. The results show that, with the increase in the AP content, the enthalpy of curing increases because of the greater formation of the bonding phase AlPO4. Both in static corrosion and in tribocorrosion, the corrosion current density of CBPCCs achieves the lowest value when the weight ratio of AP to polytetrafluoroethylene is about 0.78. Additionally, the influence mechanism of AP on tribocorrosion is clarified. AlPO4 from the reaction between AP and Al2O3 has excellent mechanical properties and can enhance the wear resistance of CBPCCs by reducing the mechanical wear and the increased wear due to corrosion. The alumina particles wrapped by AlPO4 can form a dense and smooth surface and change the direction of electrolyte propagation, which leads to the increase in the tribocorrosion resistance of CBPCCs.

“…Generally speaking, the larger the contact angle, the lower the wettability of the coating and the better the hydrophobicity, thus the contact angle can visually characterize the change of the coating surface energy. 34,35 The adhesion and impact resistance of the coating were tested by the BGD500 digital display adhesion tester and the BGD305 heavy impact tester provided by Biuged Precision Instrument (Guangzhou) Co., Ltd. The surface hardness of the coating was measured by HVS-1000ZCM-XY Vickers hardness tester (Suoyan Testing Instrument Co., Ltd.) with the hardness measurement conditions of loading load 100 g and holding time 10 s. The corrosion resistance of the coating was characterized by electrochemical workstation (CHI750E).…”

A method of preparing SiO2‐BNNSs hybrid material by surface modification of boron nitride nanosheets (BNNSs) with SiO2 was proposed to improve the dispersion of BNNSs in the coatings. Then, phosphate ceramic coatings with BNNSs and SiO2‐BNNSs were prepared on stainless steel (304) by spraying. Characterization of BNNSs and SiO2‐BNNSs by X‐ray diffraction, Fourier transform‐infrared, Raman, and scanning electron microscopy proved the success of hybridization. The surface morphology and mechanical properties were conducted to characterize the protective performance of the coating. Simultaneously, the phase composition and electrochemical properties of the coatings after high‐temperature oxidation were studied. The results showed that ceramic coatings had low surface energy with a contact angle of 102.41° when .4 wt.% SiO2‐BNNSs was added. Compared with BNNSs coating, the mechanical properties of SiO2‐BNNSs coating were significantly enhanced, the hardness of .4 wt.%SiO2‐BNNSs coating was as high as 170 HV, and the interface bonding strength was 12.24 MPa. For the oxidation corrosion resistance, .4 wt.% SiO2‐BNNSs coating under oxidation at 400°C for 50 h had the minimum corrosion current density and maximum impedance, which were .864 μA/cm2 and 177 kΩ/cm2, respectively, this indicated that SiO2‐BNNSs coating could still maintain excellent oxidation corrosion resistance under high‐temperature conditions for a long time.

[38][39][40][41] As-synthesized products were thus composed of amorphous graphite and Fe 3 O 4 . The magnetic behavior of as-synthesized porous-C/Fe 3 O 4 nanospheres was investigated by vibrating sample magnetometry (VSM) at room temperature.…”

One‐Step Synthesis and High‐Efficiency Decoloration of Multifunctional Porous‐C/Fe₃O₄ Nanospheres by Using a Sandwich‐Structured Precursor with Three Roles

A new strategy for the one‐step synthesis of multifunctional porous‐C/Fe3O4 nanospheres has been successfully developed by using ferrocenyl formic acid as a precursor. Based on its special structure, this sandwich structural precursor of ferrocenyl formic acid plays three roles in the synthesis process: it simultaneously serves as the carbon and iron source, templating agent, and pore‐forming agent. The proposed synthesis is corroborated by characterization through SEM, TEM, XRD, FTIR spectroscopy, Raman spectroscopy, BET surface area measurements, BJH distributions, and vibrating sample magnetometry. The average diameter of as‐synthesized porous‐C/Fe3O4 nanospheres is about 400 nm. Because of the porous structure of carbon nanospheres and its surface plasmon resonance with attached Fe3O4 nanoparticles, the as‐synthesized porous‐C/Fe3O4 nanospheres exhibit high activity toward the decoloration of rhodamine B. In addition, the resultant composites present ferromagnetic behavior with a magnetization saturation of 13.76 emu g−1, can be easily separated and recycled by an external magnet field for use in a variety of applications.
