“…Since the passive film formed on the surface of the titanium alloy has semiconductor characteristics, there are different types of defects presented in the passive film, including interstitial ions and vacancies, which can determine the semiconductor type and conductivity [32,33]. The Mott-Schottky theory can be used to analyze the relationship between the space charge layer differential capacitance C sc and the potential E [34].…”

In this work, the corrosion behavior of a Ti-6Al-4V alloy prepared using selective laser melting (SLM) in a 0.1 mol/L NaOH solution was studied by means of corrosion electrochemical testing, X-ray diffraction analysis and X-ray photoelectron spectroscopy (XPS), and its corrosion process was compared with the commercially forged Ti-6Al-4V alloy. The results show that the corrosion resistance of the commercially forged Ti-6Al-4V alloy was higher than the SLMed Ti-6Al-4V alloy, which is closely correlated with the presence of more active spots on the alloy surface and more defects in the passive films.

A series of electrochemical tests combined with the techniques of scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and X-ray photoelectron spectroscopy (XPS) were used to study the effect of nitrogen content on the composition, structure and protectiveness of passive films, which were formed on the surfaces of high-nitrogen austenitic stainless steels (HNSS) in 0.5 mol/L NaCl solution. The results showed that the HNSS with higher nitrogen content had a larger proportion of low-angle grain boundaries, and it also had a lower corrosion current density in 0.5 mol/L NaCl solution and thus a lower corrosion rate. The existence of a larger proportion of stable oxides (e.g., Cr2O3) in the passive films facilitates the passivation/repassivation process and contributes to the high corrosion resistance of HNSS.

“…In the ladle refining process, improving the fluid flow in the ladle plays an important role in improving the purity of liquid steel, homogenizing chemical composition, and temperature [1][2][3][4]. The water model [5][6][7] is crucial in studying the fluid flow and mixing process under different gas flow rates, locations, numbers, sizes, and separation angles of plugs in gas-stirred ladles [8][9][10][11][12][13].…”

In water model studies of mixing in ladles, the used salt tracer dosage is somehow neglected. It was reported that the salt tracer might influence the fluid flow and measured mixing time in water models. This study focuses on the effect of salt tracer dosage on the transport and mixing in a water model of a ladle with a moderate gas flow rate. The 1:3 scaled-down water model of an industrial 130 t ladle is established. Both black ink tracers for visualization of the flow field and the salt tracer for measuring the mixing time are used. The results indicate that the main circulation flow is dominant for the transport of the tracer. When increasing the salt solution tracer dosage, the arrival time at upper points is delayed, which indicates that a portion of the salt tracer is flowing downwardly to the bottom of the ladle. Consequently, the salt tracers dispersed to the bottom of the ladle are enhanced and at a faster pace. The mixing time of all monitor points decreases when the dosage of the salt tracer increases. The tendency is even obvious at the top surface.
