“…Zhang et al pointed out that the poor corrosion resistance of steel can affect the stability and safety of the material. Therefore, it is extremely important to explore the corrosion behavior of low-alloy steel for practical applications [ 38 ]. According to the literature data, it is known that many factors affect the corrosion resistance of low-alloy steels, such as: alloy content [ 39 , 40 ], Cl concentration [ 41 , 42 ], O 2 content [ 43 , 44 ], corrosion environment [ 45 , 46 ], heat treatment [ 47 , 48 ], and grain size [ 49 , 50 ].…”

“…Although tempering is an effective method of improving the mechanical properties of steel, its influence on corrosion behavior has been controversial. Therefore, Zhang et al [ 38 ] studied the effects of different tempering temperatures on the corrosion resistance of low-alloy steel in humid atmosphere using an immersion test, a salt spray test, electrochemical measurements, morphological characterization, and phase analysis. The results showed that the defects and highly reactive nature of the high angle grain boundaries of “bare” steels are preferentially corroded.…”

“…The annealed specimens corroded slightly due to the low interface energy. In the later stage of corrosion, Zhang et al [ 38 ] observed that the corrosion resistance of the analyzed samples still depends on the matrix due to the limited protection of the rust layer. Thus, the load transfer resistance improves and the corrosion resistance becomes better as the annealing temperature decreases.…”

The purpose of this study is to evaluate the corrosion resistance in natural seawater (Năvodari area) of two types of low-alloy carbon steels BVDH36 and LRAH36 by electrochemical methods. The electrochemical methods used were the evolution of the free potential (OCP), electrochemical impedance spectroscopy (EIS), polarization resistance (Rp) and corrosion rate (Vcorr), potentiodynamic polarization (PD), and cyclic voltammetry (CV). The studies were completed by ex situ characterization analyzes of the studied surfaces before and after corrosion such as: optical microscopy, scanning electron microscopy and X-ray diffraction analysis. The results of the study show us that the polarization resistance of the low-alloy carbon steel BVDH36 is higher compared to the polarization resistance of the low-alloy carbon steel LRAH36. It is also observed that with the increase in the immersion time of the samples in natural seawater, the polarization resistance of the BVDH36 alloy increases over time and finally decreases, and for the carbon steel LRAH36 the polarization resistance increases.

“…The industry constantly suffers significant losses as a result of corrosion, including degradation processes in reinforced concrete products [4]. The corrosion process affects the strength of the material and, accordingly, structures made from it, and products of degradation can cause failure of electrical equipment, plumbing, and heating systems [5]. In addition, there are indirect losses associated with the negative impact of corrosion products on the environment and a threat to safety [6].…”

Results of studying the properties of composite fluoropolymer-containing coatings formed by the cold spray (CS) method on the surface of constructional steel are presented. Different ways of protective coating formation are proposed. The composition of coatings was studied using SEM/EDX analysis. The incorporation of super-dispersed polytetrafluoroethylene (SPTFE) into the coating increases the corrosion resistance of the copper-zinc-based cold-sprayed coating. Analysis of the electrochemical properties obtained using EIS (electrochemical impedance spectroscopy) and PDP (potentiodynamic polarization) indicates that samples treated with SPTFE on a base copper-zinc coating showed lower corrosion current density and higher impedance modulus (jc = 8.5 × 10−7 A cm−2, |Z|f=0.1 Hz = 5.3 × 104 Ω∙cm2) than the specimen with cold-sprayed SPTFE (jc = 6.1 × 10−6 A cm−2, |Z|f=0.1 Hz = 8.1 × 103 Ω∙cm2). The best anticorrosion properties were revealed for the sample with a cold-sprayed base Cu-Zn layer annealed at 500 °C for 1 h, followed by SPTFE friction treatment and re-annealed at 350 °C for 1 h. The corrosion current density jc of such a coating is 25 times lower than that for the base Cu-Zn coating. The antifriction properties and hydrophobicity of the formed layers are described. Obtained results indicate that cold-sprayed polymer-containing coatings effectively improve the corrosion and wear resistivity of the treated material.
