Enhanced corrosion resistance of waterborne polyurethane

Jul 1, 2019 · The optimal corrosion resistance can be obtained by adding 0.5 wt% sulfonated graphene/zinc phosphate fillers characterized by Potentiodynamic polarization curves and EIS analysis The corrosion current density (i corr) was 0.4252 μA/cm 2 and the charged transfer resistance (R ct) was up to 10.937 × 10 3 Ω cm 2, which show a good potential as

Fabricating an epoxy composite coating with enhanced

Dec 1, 2017 · The influence of nanoclay particles modified by polyester-amide hyperbranched on the corrosion resistance increment of epoxy coating has been shown in our previous study [29]. Behzadnasab et al. showed beneficial role of using combination of clay and zirconia nanoparticles on the improvement of the epoxy coating corrosion resistance [36].

Enhanced corrosion performance by controlling grain boundary

Feb 1, 2024 · The corrosion resistance is closely related to the composition, in particular the content and ratio of the main alloying elements Cu, Mg, and Zn. Mo et al. [ 19 ] reported that trace amounts of Zn (0.67 wt%) widened the PFZ of the 2024 Al alloys, and increased the sensitivity and corrosion depth of IGC.

Enhanced corrosion resistance by engineering crystallography

Feb 7, 2022 · Here we show, by engineering crystallographic configurations upon metal matrices adjacent to their passive films, we obtain great enhancement of corrosion resistance of FeCr15Ni15 single

Superhydrophobic composite coatings in bacterial culture

Oct 1, 2021 · After 21 days of immersion in Pseudomonas aeruginosa (P. aeruginosa) inoculated media, the results of antibacterial testing and electrochemical characterization in an erosive environment showed that superhydrophobicity significantly inhibited the adhesion of the P. aeruginosa cells and enhanced the corrosion resistance of the composite coating.

Enhanced Bio-corrosion Resistance by Cu Alloying in a Micro

Feb 27, 2022 · On the composition base of commercial X65 grade pipeline steels, a Cu modified pipeline steel was designed to show improved resistance to microbially induced corrosion (MIC). The mechanical properties of the Cu-added steel and its corrosion behavior in a soil solution inoculated with sulfate-reducing bacteria (SRB) were investigated in this work. The results demonstrated that Cu-added steel

Application of layered double hydroxides (LDHs) in corrosion

Nov 8, 2021 · The corrosion inhibition effect of INT-LDHs on steel bars is statistically shown in Table 2, where R ct /R p is the charge transfer resistance/polarization resistance; η is the corrosion inhibition efficiency. It can be seen that INT-LDHs can effectively enhance the charge transfer resistance of carbon steel, the corrosion inhibition

Enhanced antibacterial efficacies, corrosion resistance, and

Oct 30, 2023 · Coatings enhanced the hydrophilicity and corrosion resistance of Ti substrate. Multi-mechanisms made the antibacterial rate reach 99.99% within 0.5 h contact. Composite coatings promoted the proliferation and adhesion of MC3T3-E1 cells.

Enhanced corrosion resistance, antibacterial activity and

Jun 1, 2022 · In the previous research of our group [38, 43], it is found that the MMT coating on the surface of AZ31 prepared via hydrothermal method has excellent corrosion resistance. Therefore, the corrosion resistance of GS/MMT coating was tested. Hereby the GS concentration used in the corrosion resistance tests is set at 2.5 mg/ml on the basis of our

Electro-brush plating Ni-Graphene oxide composite coating

Feb 19, 2021 · The addition of GO will enhance the corrosion resistance of the composite nickel coating, which the fluoride ion preferentially bonded with nickel and prevent corrosive medium entering the active area. And there is an optimum GO content amount in Ni-GO composite coatings for achieving the highest corrosion resistance(Ni-GO/0.75 composite coating).

Enhanced corrosion resistance of additively manufactured

Jan 20, 2022 · The absence of sulfur-containing oxide-inclusions in SLM-316L/CrN and refined cellular structure, and the change in chemical composition were attributed to corrosion resistance enhancement due to

Corrosion Resistance of Concrete - Cement

Corrosion of this rebar caused spalling on a concrete step. The corrosion of reinforcing steel can be a problem in concrete structures. Corrosion of steel produces hydrated iron oxide or rust, which is very expansive. This expansion builds up internal pressure until the concrete fails in the form of spalling. This is a leading cause of concrete

Compost Process and Organic Fertilizers Application in China

Jun 30, 2016 · Composting is an inexpensive and sustainable treatment for solid wastes. The composting industry has been growing rapidly because of a boom in the animal industry in China over the past decades. In this chapter, we introduce composting process and status in China, especially in Jiangsu Province. Meanwhile, the developed novel spectroscopy techniques are also introduced, which are more suitable

Enhanced corrosion resistance of CPC coatings modified with

Apr 18, 2023 · The significantly lower I corr value of 8.92e-08 μA (a order of magnitude less than reinforcements without coating) and the highest impedance value and polarization resistance, implied more corrosion resistance for OPR coated rebars than others. The characterization of the surfaces revealed the smooth morphology of the OPR coating.
