Special Issue Information

Dear Colleagues,

Corrosion science is an interdisciplinary frontier science. The huge impact of corrosion on the economy, environment, and safety causes countries to invest huge amounts of manpower and funds into the field of corrosion protection. The direct economic losses that are caused by metal corrosion around the world account for about 2% ~ 4% of the GDP every year. By using available corrosion control practices, 15%-35% savings in corrosion costs could be realized.

This Special Issue intends to outline the fundamental development trends in the field together with the most recent advances in corrosion science research on the metal matrix composites–corrosion mechanism, corrosion electrochemistry, corrosion simulation, the natural environment corrosion, high-temperature corrosion, mechanochemical corrosion, multiphase flow corrosion, microbiology corrosion, etc. All of these topics will be covered in this collection of contributions, as will a large assortment of metal matrix composites, including particle- or fiber-reinforced metal (Al, Mg, Ni, Ti, etc.), superalloy and intermetallic compound matrix composites, etc., together with information on their use.

In this Special Issue, we also welcome articles that focus on corrosion protection methods for metal matrix compotites and their influence on the performance of the final product, both from the perspectives of advanced experimental characterization and/or engineering applications.

Contributions will be considered noteworthy if they represent a novelty corrosion phenomenon, propose a new corrosion simulation method, advance an innovative corrosion mechanism, and use plating/coating for effective protection in the world of metal matrix composites.

Carbon nanoparticles have excellent lubricating properties, however, they are less involved in metal protection. In this study, easily prepared candle soot was added to electroless nickel-phosphorus plating as a re-enforcement particle. Ball-disc friction and wear tests were conducted to evaluate the wear-resistance capabilities of the electroless Ni-P coating and Ni-P-CS (Candle Soot) composite coatings. The parameters for the friction coefficient, wear amount, and friction morphology of the Ni-P-CS composite coatings were studied after being heat-treated (300 °C, 400 °C, 500 °C, and 600 °C). The surface morphology and phase composition of the Ni-P-CS composite coatings after thermal treatment at various temperatures were also investigated. The results are as follows: heat treatment strengthens the local hardness of the Ni-P-CS composite coating but does not further enhance wear resistance. Compared with the Ni-P coating and the heat-treated Ni-P-CS composite coating, the Ni-P-CS composite coatings without heat treatment have a lower friction coefficient (0.35) and better wear resistance.

Fluid-induced metal corrosion failure is one of the main causes of pipe wall damage. In this paper, aimed at the corrosion failure of stainless-steel pipe wall in high-speed flowing liquid, a self-made micro three-electrode electrochemical test system was used to test the electrochemical characteristics of the pipe under different flow rates and different Cl− concentrations. In the experiment, the changes of open circuit potential, polarization curve and impedance spectrum of 304L stainless steel surface were obtained. At the same time, the corrosion rate of the material under different conditions was obtained by fitting. The results show that the corrosion rate varied non-linearly with increasing flow velocities. In addition, with the increase of Cl− concentration, the corrosion rate increased at a slower rate. The material surface under high concentration and high flow rate conditions was subject to physical cutting and electrochemical reactions, showing an activated and easy pitting corrosion state. The results of this study can provide data for failure analysis and life extension of pipelines and equipment in service. Full article

In this work, effects and mechanism analysis of samarium acetate and ytterbium acetate on enhancing the electrochemical corrosion performance of aluminum-based anode for aluminum-air batteries in 3.5 wt.% NaCl are studied by methods such as weight loss tests, electrochemical measurements, anode galvanostatic discharge tests and microscopic morphology analysis. The results show that samarium acetate and ytterbium acetate are ideal electrolyte additives, and exhibit obvious inhibitory effects on the self-corrosion of 7075 aluminum alloy. The optimal concentration is 200 mg/L. Moreover, corrosion inhibitors mainly reduce the self-corrosion speed of aluminum by suppressing the microcathodic reaction, thereby promoting the improvement of the discharge performance of aluminum-air batteries. Simultaneously, it is found that after mixing samarium acetate and ytterbium acetate in different proportions, the two rare earth salts have a mutual adjustment effect. By adding different rare earth salt components, the battery capacity densities of the anode are improved by 9.6% to 16.3%. Finally, a possible model is presented to illustrate the impact mechanism of different additives on the self-corrosion process and discharge performance of aluminum-air batteries. Full article

The adsorption characteristics of corrosive anions (Cl−, HS−, S2−, HCO3− and CO32−) on TiO2 of TC4 titanium alloy in a NaCl solution containing H2S and CO2 were studied by density functional theory (DFT). The stable adsorption configuration of each corrosive species on the TiO2 (110) surface was obtained by geometric optimization, and the electronic structure and interface binding energy were calculated and analyzed. The results showed that the optimal adsorption positions of Cl−, HS−, S2−, HCO3− and CO32− on TiO2 (110) were all bridge positions. There was a strong charge interaction between the negatively charged Cl, S and O atoms in Cl−, HS−, S2−, HCO3− and CO32− and the positively charged Ti atoms of TiO2. The interface bonding was mainly caused by charge movement from around Ti atoms to around Cl, O, S atoms. The energy levels were mainly caused by the electron orbital hybridization of Cl-3p5, S-3p4, O-2p4 and Ti-3d2. All adsorption configurations were chemical adsorption. The order of influence of the five ions on the stability of TiO2 was S2− > CO32− > Cl− > HS− > HCO3−. Finally, a novel corrosion mechanism was proposed to illustrate the dynamic evolution processes of pits. Full article
