“…runwhere e is the dielectric constant of the passive film (12 for Cr 2 O 3 (Ref 13,43)), e 0 is the vacuum permittivity constant (8.854910 À14 F/cm), e is the elementary charge (1.602910 À19 C), A is the electrode surface area, V is the applied potential, V FB is the flat band potential, k B is the Boltzmann constant (1.38910 À23 J/K), T is the absolute temperature, N D is the donor density, and N A is the donor density. Thus, a positive slope corresponds to n-type semiconductors, and a negative slope corresponds to p-type semiconductors.…”

The corrosion behavior of an Inconel 718 alloy fabricated using the selective laser melting (SLM) technique in a 3.5 wt.% NaCl solution is determined. The corrosive effect of the NaCl solution on the Inconel 718 alloy is investigated using potentiodynamic polarization curve measurements, Mott-Schottky plots, electrochemical impedance spectroscopy, atomic force microscopy, and x-ray photoelectron spectroscopy (XPS) and is compared with that on a commercially rolled Inconel 718 alloy (R 718). Electrochemical results suggest that the application of SLM to the Inconel 718 alloy lowers its corrosion resistance. The passive films formed on both alloys show p-type and n-type semiconductor behaviors. However, the concentrations of the defects in the passive films formed on the surface of the SLM Inconel 718 alloy are higher than those on the surface of the commercially rolled R 718. XPS shows that the passive film formed on the SLM Inconel 718 alloy has a higher NiO content, leading to the deterioration of its protective properties.

“…Before the experiment, the surface of the samples was polished down to 800# with sandpaper and then cleaned using deionized water, acetone, and anhydrous ethanol. The potentiodynamic polarization test was carried out using the CS310 electrochemical workstation; the detailed introduction of the electrochemical experimental design methods was presented in the literature [ 1 , 2 ]. The test solution was consistent with the immersion test, and the test temperature was 25°C.…”

“…In the existing nuclear power plants, the SEC pipes were made of stainless steel [ 2 , 3 ], carbon steel lined with coating, rubber, plastic or cement mortar, and resin pipes. During the service of the SEC pipes, the addition of the cupric fungicide to prevent microbial corrosion, the corrosion of copper components, or other reasons could lead to the local enrichment of Cu 2+ in the SEC system and the precipitation of Cu on the surface of components; the interaction between Cu 2+ and seawater may accelerate the corrosion of SEC system material, even leading to the breaking of the components and inducing the addition of Cu 2+ into the secondary circuit system.…”

The corrosion behaviors of A106B carbon steel and 304L stainless steel (SS) in seawater with different Cu2+ concentrations were studied by the immersion test and the potentiodynamic polarization test. The results showed that with the increasing Cu2+ concentration, the mass lot rates of A106B and 304L SS all increased in the immersion test, and compared with A106B, the mass lot rates of 304L SS were all smaller. In the potentiodynamic polarization test, following the concentration of Cu2+ increased, the corrosion potential of A106B firstly shifted negatively; then, when Cu2+ increased to 100 ppm, the polarization curve moved to the upper right direction; namely, both the corrosion potential and corrosion electrical density increased. The corrosion potential of 304L SS increased with the increasing Cu2+, and the passive region was reduced; the pitting sensitivity improved.

“…The essence of copyrolysis of oily sludge and biomass is to catalyze and strengthen the pyrolysis of oily sludge, enhance the rate of oil and gas recovery, and improve the oil and gas quality. Common biomass catalysts include rice husks, walnut husks, wood chips, and apricot husks [39]. Not only can be used as a catalyst, but also other catalysts can be supported, so that the catalytic effect is better, and the reaction system is not required.…”

The main methods of treating oily sludge at home and abroad and the current research status of oily sludge pyrolysis technology are briefly described, and four commonly used catalysts are introduced: metals, metal compounds, molecular sieves, metal-supported molecular sieves, and biomass catalysts for oily sludge. The influence of pyrolysis, the pyrolysis mechanism, and the product composition of oily sludge with the addition of different catalysts are also discussed. Finally, the development direction of preparing new catalysts and the mixed use of multiple catalysts is proposed as a theory to provide for the efficient and reasonable utilization of oily sludge.
