“…Furthermore, the contact damage tests were in complete agreement with previous micromechanical tests in terms of crack propagation paths in carbonitride systems [6]. Recently, a new experimental set-up designed by the authors was used to investigate the cyclic contact fatigue behavior of cemented carbides under dry and wet conditions [7]. By immersing the cemented carbides in industrial cutting fluid under oscillating loads, the combination of chemical attack and cyclic contact load was used to visualize the advantage of Cr-containing binders in the corrosion-fatigue resistance of commercial cemented carbide grades.…”

“…The force range (ΔF) was constant with an indentation force ratio of 0.17 (ΔF = 200 N/1200 N), allowing the indenter to be in contact with the material surface during the entire experiment. For wet experiments, an industrial cooling fluid (8 vol% stock solution in tap water) was used, Tab.1 [7].…”

“…The longer the drying time was, the more serious the metal corrosion was. Generally speaking, the more serious corrosion under drywet alternating was due to the decrease of the surface liquid film thickness during the dry process, and oxygen was more easily transported in the liquid film, promoting the cathode reaction process [10][11][12][13].…”

The coastal pipelines are the key link between the offshore and the onshore pipelines, which are located in the soil dry-wet alternating environment. Even though higher corrosion risk of metals in coastal soil dry-wet alternating environment, few papers focused on this condition, while much research about ocean and atmospheric dry-wet alternating environment was paid attention to. In this paper, a self-designed soil dry-wet alternating experimental device was used to investigate the corrosion characteristics of Q235 steel in seawater, soil and dry-wet alternating environment based on mass loss experiments, corrosion morphology analysis and electrochemical experiments. The results showed that the general corrosion rate of Q235 steel in soil and seawater environments basically remained unchanged, and in dry-wet alternating environment increased with time, while the pitting rates were 0.280 mm/a (soil), 0.420 mm/a (seawater) and 0.567 mm/a (dry-wet alternation), respectively, which was caused by the oxygen concentration cell and salt concentration cell. Meanwhile, the growth rate of pitting size in dry-wet alternating environment was much higher than that in the other two environments with different corrosion characteristics of pitting corrosion (seawater and dry-wet alternation) and a changed from general corrosion to pitting corrosion (soil). In three environments, the corrosion current density (I corr) increased, in which on the 30th day of experiment, I corr = 79.72 μA/cm2 in dry-wet alternating environment, which was much higher than I corr = 47.89 μA/cm2 in seawater environment. In dry-wet alternating environment, the mass diffusion impedance at 10-2 Hz and the maximum phase angle changed significantly, while the logf-log|Z| curve in low-middle frequency decreased significantly, and charge transfer resistance at 105 Hz reduced from 10.4 Ω to 4.3 Ω, illustrating an increasing corrosion rate.

Studies on jet grouting materials mainly focus on the aggregates in cement or the environment where they are maintained and rarely deal with the cohesiveness, reinforcement load-bearing characteristics, and surface spalling. In this study, cement slurries with different colloid contents were prepared to explore the characteristics and reinforcement effect of broken gangues. These were then subjected to mechanical testing to measure the strength and axial strain performance, and the failure modes and failure patterns were discussed. The results indicated that the colloid component has a significant strengthening effect on the early strength of the samples. As the age increased, the sample axial strain and elastic modulus of the colloid cement paste increased as the colloid component provides viscoelasticity when it resists deformation. The sample strength of cement paste decreases after the addition of broken gangue while the strength of class E samples increases significantly during each age. The cement paste sample showed penetrating splitting failure, the colloidal component effectively controlled the peeling of sample surface, and the failure mode after adding gangue was relatively complicated. The instability modes of the samples are divided into dispersed load-bearing instability and cumulative load-bearing instability, and the content of colloid components affects the failure mode of the samples. A colloid component proportion of 23.33% is the optimal choice, which has an obvious reinforcement effect on the broken gangue.
