Special Issue Information

Dear Colleagues,

Corrosion of metallic materials is an important research field involving materials, environment, and engineering. With the process of industrialization and the continuous development of advanced technology, the economic losses and security risks caused by corrosion and failure have attracted widespread attention. In order to solve the problem of corrosion and the failure of engineering structures and materials, many research institutions and scientists are committed to relevant research involving corrosion mechanisms, corrosion test methods and simulation, engineering failure cause analysis, corrosion prediction and evaluation, protective measures, and material design. These research results can provide practical guidance to engineers and scientists to help them solve practical problems.

In this Special Issue, we welcome articles that focus on corrosion mechanisms and failure analyses of materials used in the field of aerospace, marine, energy. and chemical industries, etc. Methods to solve corrosion problems are also welcome. The main purpose of this Special Issue is to promote the academic research and technological innovation of corrosion and protection disciplines. At the same time, it can also provide a reference and guidance for engineering practice, helping people to understand corrosion and failure mechanisms and causes and then choose appropriate anti-corrosion measures and materials to reduce the risk and loss caused by corrosion failure.

Titanium (Ti) alloys are widely used in biomedical applications but face challenges like poor biological activity and corrosion at modular interfaces. Strontium (Sr)-doped micro-arc oxidation (MAO) surfaces are proposed to improve biocompatibility and tribocorrosion resistance. This study examines the electrochemical behaviour of Ti surfaces treated with 0.0013 M and 0.13 M Sr-doped MAO via open circuit potential, potentiodynamic polarisation, and electrochemical impedance spectroscopy in a basic physiological solution at 37 °C. The results indicate that higher Sr concentrations led to lower passivation current densities (more than two times lower than at the lowest Sr concentration) and reduced barrier layer capacitance (more than one and a half times lower than at the lowest Sr concentration), suggesting improved corrosion resistance for Sr-enriched MAO treatments on Ti implants.

High-chromium white iron (HCWI) alloys are often used in industries such as mining which require a high wear resistance. Whilst nitrogen is known as a good austenitic stabiliser, the effects of nitrogen on corrosion properties for welded HCWI have not been studied. Chromium hardfacing alloys were deposited via gas metal arc welding using nitrogen as a shielding gas at flow rates of 5 L/min, 10 L/min, and 15 L/min. The corrosion behaviour of these modified alloys was studied using electrochemical techniques such as potentiodynamic measurements and electrochemical impedance spectroscopy. Higher gas flow rates were found to increase the volume fraction of the eutectic austenite while reducing the amounts of eutectic carbides. Nitrogen did not transform the M7C3 (M = Cr, Fe) carbides into any other form of carbides. The sample without nitrogen as a shielding gas was found to display the worst corrosion resistance after electrochemical testing, such as corrosion resistance parameters in EIS tests. Higher nitrogen shielding gas flow rates were found to produce higher levels of corrosion resistance; this was especially true for the 15 L/min sample with a corrosion resistance parameter to EIS that was more than double that of the sample without nitrogen shielding gas (e.g., 4700 vs. 2325 Ω·cm2 respectively).

The development of environmentally friendly materials is a subject of increasing interest in corrosion protection research. The objective of the present investigation is to propose the preparation procedure of chitosan–alginate (CHI/ALG) nanocontainers loaded with zinc oxide (ZnO) nanoparticles or combining ZnO nanoparticles with corrosion inhibitor caffeine (CAF), both suitable for incorporation into the matrix of ordinary zinc coatings on mild steel substrates. The nanocontainers were synthesized through spontaneous polysaccharide complexation in the presence of ZnO nanoparticles and CAF using a cross-linking agent, namely tripolyphosphate (TPP). Dynamic light scattering and laser Doppler velocimetry measurements are used for evaluation of the size distribution and zeta potentials of the nanocontainers, both loaded or unloaded with CAF. Using UV-spectroscopy, entrapment efficiency and release amounts of CAF are quantitatively evaluated. The nanocontainers thus obtained were incorporated into the matrices of ordinary zinc coatings via co-electrodeposition with zinc from zinc sulfate solution, aiming to improve the corrosion protection of steel in corrosive environments containing chloride ions. The surface morphology and elemental composition of the electrodeposited hybrid coatings before and after treating in the model corrosive medium of 3.5% NaCl is studied by scanning electron microscopy (SEM). The cyclic voltammetry method (CVA) is applied to characterize the cathodic (electrodeposition) and anodic (dissolution) processes. The protective characteristics of the hybrid coatings are investigated by application of potentiodynamic polarization (PDP) curves and polarization resistance (Rp) measurements after a time interval of 40 days. The obtained results indicate that both hybrid coating types could prolong the life time of mild steel in aggressive Cl− ion-containing solution, combining the protection effect of sacrificial zinc with barrier (ZnO) and active (CAF) protective effects.
