Relationship between wetted and corroded areas on 8Cr4Mo4V bearing steel during exposure to salt water contaminated lubricant oil was explored by Monte Carlo simulation and corrosion experiment. Results show that locally corroded areas are initially scattered then connected and eventually merged due to droplet coalescence, and are resulted from galvanic, uniform and filiform corrosions, respectively. Droplet coalescence also redistributes wetted areas and activates de-wetting which interrupts transformation towards corrosion. Role of droplet coalescence in evolution of corroded areas is addressed. Combining two Monte Carlo models varied with droplet relaxation helps to predict the corroded areas' distribution after long-term exposure.

Quenching and partitioning (Q&P) steels are extensively used in the automotive industry due to their exceptional strength and ductility. However, the impact of hydrogen embrittlement (HE) poses a huge challenge to the safe service of Q&P steels, highlighting the necessity to investigate the hydrogen-induced cracking mechanisms. This study investigates the hydrogen-induced failure mechanisms in Q&P steels through experiments and finite element simulations, focusing on microstructure, local stress heterogeneity, hydrogen distribution characteristics, and hydrogen-induced cracking. The results reveal that hydrogen cracking nucleation in Q&P steel is primarily due to the further accumulation of hydrogen in local high-stress martensitic/austenitic regions.

The impact fretting corrosion of Inconel 690TT under different impact forces was investigated. The results indicated that there was a competitive relationship between formation of third body layer (TBL) and fragmentation of TBL caused by impact force. With the increase of impact forces, damage mechanism changed from adhesive wear to delamination wear, and crack initiation sites gradually shifted from TBL to internal oxidation zone in tribologically transformed structure (TTS) layer. Nanocrystalline boundaries and defects induced by impact force provided channels for internal oxidation. The formation mechanism of TTS was the combined effect of continuous dynamic recrystallization (cDRX) and twin-assisted cDRX.

A new strategy of utilizing mixtures of ethanol and complexing agents on Mg-air battery is investigated systematically. The presence of ethanol promotes formation of a dense inner layer with a high portion of oxide in the discharge film, leading to significantly enhanced utilization efficiency. The highest utilization efficiency of Mg anode has been increased from 53.6 % to 85.7 % and the discharge potential is decreased 300 mV, when discharges in mixed electrolyte. The adsorption/deposition of S-like species on metal surface is evidenced in ethanol and 5-sulfosalicylate acid containing solution, resulting in inhibition of the hydroxide-rich outer layer growth.

A mass transfer model for corrosion products (CPs) in a liquid metal cooling system has been developed. The spatial variations in CPs concentration are determined by integrating the source term of the mass transfer model with models for radial iron dissolution, precipitation, particle deposition, and erosion. The model has been validated and verified using experimental data from a lead-cool loop and air. Subsequently, it has been applied to analyze the multi-modular lead-bismuth eutectic (LBE) loop. The results reveal the CPs transfer rate, CPs concentration distribution, overall corrosion characteristics, and the impact of CPs mass transfer on corrosion behavior.

In this research, the effects of hard anodizing on the mechanical and electrochemical characteristics of aluminum alloys under tribocorrosion conditions was investigated. Compared with dry conditions, friction coefficient of aluminum alloys under tribocorrosion conditions increased, whereas that of hard anodized specimens decreased. This was attributed to corrosive ions in the solution corroding the transfer film of the counter-body and tribofilm of the hard anodized specimen. In potentiodynamic polarization experiments under tribocorrosion conditions, the aluminum alloys exhibited high current density with applied load. However, at potentials above –0.05 V, current density decreased and was reversed. This is believed to be due to the corrosive ions preferentially reacting with the generated wear debris, thereby reducing the oxidation reaction with wear track. However, the current density of the hard anodized specimens increased with load and potential. In addition, the increasing rate in the wear width and depth was significant under tribocorrosion conditions (Width: 42.65 %, Depth: 32.63 %). This is due to the cavitation and fluid impact generated during friction/wear accelerating the cracking and damage of the hard anodizing film with the brittleness and porousity. However, the tribocorrosion resistance of the hard anodized aluminum alloy was improved by more than 97 %.
本研究调查了硬质阳极氧化对摩擦腐蚀条件下铝合金机械和电化学特性的影响。与干燥条件相比，摩擦腐蚀条件下铝合金的摩擦系数增大，而硬质阳极氧化试样的摩擦系数减小。这归因于溶液中的腐蚀性离子腐蚀了硬质阳极氧化试样的对体和三膜的转移膜。在摩擦腐蚀条件下进行的电位极化实验中，铝合金在施加负载时表现出很高的电流密度。然而，当电位高于 -0.05 V 时，电流密度下降并发生逆转。这被认为是由于腐蚀离子优先与产生的磨损碎片发生反应，从而减少了与磨损轨迹的氧化反应。然而，硬质阳极氧化试样的电流密度随着负载和电位的增加而增加。此外，在摩擦腐蚀条件下，磨损宽度和深度的增加率也很明显（宽度：42.65 %，深度：32.63 %）。这是由于摩擦/磨损过程中产生的气穴和流体冲击加速了脆性和多孔性硬阳极氧化膜的开裂和损坏。不过，硬质阳极氧化铝合金的耐摩擦腐蚀性能提高了 97% 以上。

The anodic dissolution behaviors of TA2 under elastic stress in acidic 3.5 % NaCl solution with or without 5 mM NaF were investigated using in-situ scanning electrochemical microscopy (SECM), along with polarization curve, SEM and AFM. The results indicated that the dissolution of the passive film in 3.5 % NaCl solution was accelerated under 100 MPa, and more resistant to dissolve under 200 MPa. In presence of 5 mM NaF, the stress intensified the dissolution of the matrix. Specifically, 100 MPa stress increased the corrosion difference between different grains, while 200 MPa stress made the corrosion of TA2 more uniform.

Multi-layer 2219 aluminum alloy samples were successfully fabricated using additive friction stir deposition (AFSD). AFSD deposition reduced grain size and the size of intermetallic Al2Cu particles, but greatly increased the amount of Al2Cu particles. More Al2Cu particles increased the number of galvanic microcells on alloy surface and at the grain boundaries, which promoted the localized corrosion and improved the intergranular corrosion sensitivity of AFSD alloy. Subsequent T6 heat treatment had little effect on grain size but enhanced the corrosion resistance of AFSD alloy, primarily attributed to the reduction in Al2Cu particles and the elimination of dislocations within grains.

Micro Sm alloying coupling with four-pass rotary rolling is conducted to synergize the corrosion resistance and mechanical properties of Mg-Al-Sn-Ca-Mn alloys. Micro Sm alloying weakens the galvanic corrosion. Rolling process refines the grains, intensifies the basal texture and promotes dispersed second phase particles, thereby contributing to forming a uniform and protective corrosion product film, and enhancing the mechanical strength and ductility. As a result, rolled Mg-Al-Sn-Ca-Mn-Sm alloy exhibits a synergy of mechanical properties and corrosion resistance, i.e., an UTS of 271 MPa, YS of 204 MPa, elongation to failure of 18 %, and a low corrosion rate of 0.85 mm y−1.
