“…E690 steel is a high-strength low-alloy (HSLA) steel that is commonly used in marine applications due to its excellent strength [28], toughness, and corrosion resistance properties [29,30]. E690 steel is often used in the construction of ships and other marine vessels; it can be used for various components of the ship, including the hull, superstructure, and deck.…”

This study investigates the impact of Ca and Sb elements on the corrosion resistance of E690 steel in a simulated marine environment. Electrochemical testing and dry/wet cyclic corrosion testing were conducted on prepared E690 steel specimens. The eroded specimens’ microstructure was observed under a scanning electron microscope, and the inclusion morphology was analyzed using an energy-dispersive spectrometer (EDS). The simulating liquid was designed to emulate the severe marine atmospheric environment in Xisha. Results showed that the addition of Ca and Sb elements effectively enhances the corrosion resistance of E690 steel in the simulated marine environment. The corrosion rates of E690 steel specimens with Ca and Sb additions were lower than those without, and the corrosion morphology was more uniform. These findings suggest that the addition of Ca and Sb elements can improve the corrosion resistance of E690 steel in simulated marine environments and have potential for use in marine engineering applications.

“…Chi et al [15] studied the stress corrosion behavior of Ti-6Al-4V alloy in simulated saltwater solution and found that α grain orientation affected the crack propagation path, thereby affecting the stress corrosion sensitivity of the titanium alloy. Li et al [16] studied the stress corrosion behavior of steel in artificial seawater and found that cracks tend to initiate and propagate along the <111> orientation according to the grain orientation map. Frank et al [17] discovered that the number density of crack initiation sites on nanocrystals was heavily dependent on the crystallographic grain surface orientation.…”

This study investigated the tensile deformation of Ti-6Al-4V ELI titanium alloy and its effect on corrosion performance. The results showed that the structural morphology of the samples’ strain levels of 0%, 5%, and 10% had minimal changes under an optical microscope. Further investigation of grain orientation information was conducted using electron backscatter diffraction (EBSD), revealing that tensile deformation induced grain rotation, resulting in the diversity of originally preferred orientation grains and a decrease in texture strength. A small amount of {10–12}<−1011> extension twinning formed during the tensile deformation process. The electrochemical properties of Ti-6Al-4V ELI samples with different strain levels were evaluated in 3.5% NaCl solution with pH values of 7 and 1.5. The results indicated that both plastic deformation and acidic environments were detrimental to the passivation film on the titanium alloy surface, leading to reduced corrosion resistance.

“…Compared with other maintenance equipment, shot blasting has huge advantages in terms of economy, environmental protection and efficiency. [1][2][3] Horizontal movable shot blasting machine can realize automatic recovery of shot, but in actual production and processing, it is difficult to recover the waste produced after shot blasting, and the dust particles generated during the recovery process are easy to cause environmental pollution, and the constructor is easy to cause lung disease due to inhalation of large amount of dust. 4 Studies have shown that when the efficiency of waste recovery reaches 95%, it is a relatively efficient and environmental friendly recovery efficiency.…”

The shot blasting machine recovery device is an important part of the operation of the shot blasting machine to recover solid particles and reduce environmental pollution. The recovery efficiency of solid particles has an important influence on their processing efficiency and service life. The computational fluid dynamics and discrete element method (CFD-DEM) simulation method is applied to study the gas-solid two-phase flow characteristics and solid particle recovery efficiency of shot pellet recovery unit. The results show that the simulation results of outlet and inlet wind speeds and pressures are in good agreement with the experimental data, which verifies the accuracy of the simulation model. The existence of particle phase divides the recovery pipeline into inner high-speed flow area and outer low-speed flow area, which has little influence on the air flow distribution inside the recovery bin. The results of solid particle recovery efficiency show that with the increase of incident angle, the recovery efficiency of waste particles and shot particles first decreases and then increases, and the recovery efficiency is the lowest when the incident angle is 30°. With the increase of particle formation rate, the efficiency of shot recovery first increases and then decreases. When the particle formation rate is 2000 n/s, the efficiency of shot recovery is the highest, which has little influence on the efficiency of waste recovery.
