Excerpts

As the load increases, the cross-sectional area reduction in the 0.2C alloy shows a decreasing trend after corrosion wear compared with dry sliding wear, while the opposite trend is observed in the 2C alloy.

The COF shows an increasing trend with load in HCl tribocorrosion.

The size and phase fraction of the Ni 3 Mo 3 C ffswfswephase showed a trend of first increasing and then decreasing, and the changing trends were not completely synchronous.

As the heater rotates gradually towards the bottom of the tundish around channel 1, the EMF along the centerline of both channels shows a decreasing trend.

From the simulation results, it was observed that at a depth of 3 cm, the simulated stress values at wheel speeds of 11 m/s and 15 m/s were 9.35 MPa and 10.27 MPa, respectively, indicating an increasing trend in stress simulation.

However, at a pavement depth of 8 cm, the simulated stress values at wheel speeds of 11 m/s and 15 m/s were 1.37 MPa and 1.34 MPa, respectively, showing a decreasing trend in the stress simulation.

Further examination of the individual predictors, v f , m a , and SoD shows that all are highly significant contributors to the model (α = 0.05).

As shown in Figure 13 a, for the same offset, the unevenness coefficient shows a decreasing trend from rectangular to trapezoidal to involute on the whole, although the trapezoidal tooth increases little compared to the involute tooth at 0.04° offset.

In terms of peak stress, as shown in Figure 12 b, for the same teeth count, the peak stress increases with the offset; for the same offset, there is an overall trend where more teeth lead to lower peak stress on the separator plate.

However, the wear mass loss of samples A2, A3, and A4 reveals a decreasing trend with an increasing content of ZrB 2 .

The results found that K-B-G* shows an increasing trend with increasing loading frequency, indicating that the interaction ability of asphalt and mineral filler is affected by the loading frequency.

The results show that, with the increase in frequency, the single-pulse discharge energy decreases continuously, and the coating thickness shows a decreasing trend, from the highest value of 152 μm at 400 Hz to the lowest value of 87.5 μm at 1000 Hz.

On the other hand, although the total manufacturing time of the theoretical WAAM tooling also following a decreasing trend with the reduction in design over-thicknesses, this most favourable case still requires a total manufacturing time three times longer than pure machining tooling.

In the optimized surface roughness fitting model, the p -value of the working gap h ( B ) is <0.0001, indicating that it is a highly significant factor; the p -values of the polishing tool speed n c ( A ) and abrasive particle size r ( C ) are both less than 0.05, indicating that they are significant factors.

Under other working gaps, the minimum magnetic field strength shows a decreasing trend.

Additionally, the flexural strength of the GMPF samples with a 3.0 vol% polypropylene fiber dosage shows a decreasing trend, with a 7.1% decrease compared to the preceding group.

Furthermore, polypropylene fibers significantly improved the matrix’s flexural toughness, which showed an increasing trend with higher fiber content.

As the Al content increases from 6 at.% to 14 at.%, the combustion enthalpy of the alloys has a slightly increasing trend ( Figure 7 a), from 10.826 KJ/g at x = 0 at.% to 11.749 KJ/g at x = 8 at.%.

Upon cell activation, the capacity of the electrodes shows an increasing trend, which was followed by a gradual stabilization.

Overall, as the temperature increased, the sample exhibited a significant trend of radial shrinkage.

The F -value of 66.94 and the adjusted regression coefficient above 99% indicate that the model equation is highly significant.

Fineness, measured via an air permeability apparatus, was approximately 3600–4000 cm 2 /g and showed a trend of increasing as the limestone content increased.

By considering these results, an unexpected trend can be noticed: with the increase in elongation, the breaking angle also increases.

The influence of the STR is more pronounced for Mg and Cu alloys than for Zn alloys, while the fraction of the eutectic phase shows an increasing trend with increasing Zn, Mg, and Cu content.

As shown in Figure 4 g,h, water content at both loading current densities has a decreasing trend with an increasing stoichiometric ratio, and a stoichiometric ratio of 100 generates more water content than a stoichiometric ratio of 400.
