With the increasing normal loads from 10 to 50 N, the wear volume loss and coefficient of friction of the coating increased, owing to transition from the mild to severe wear.
Parameters such as the molar volume, the volume coefficient of thermal expansion, the rheochor and the activation entropy and enthalpy in the Eyring's equation were determined.
The variations in density, packing density and coefficient of volume expansion were evaluated and then compared with the free-volume holes deduced from positron annihilation spectroscopy lifetime and to moisture absorption.
Furthermore, it is shown that the trends in density and coefficient of volume thermal expansion with chain length obtained from simulations are consistent with an ideal mixing approximation.
The effects of sliding distance on both the worn volume and the coefficient of friction were examined.
where, ρf, μ, and β are the density, viscosity, and volumetric volume expansion coefficient of the fluid, while ρp is the density of the particles.
However, it was highly correlated with hand volume with coefficient of correlation of 0.845, 0.886 and 0.692 on X-, Y- and Z-axes, respectively.
They also demonstrated a relationship between the circulating angiogenic biomarkers and DCE-MRI imaging biomarkers: a negative relationship with fractional blood plasma volume (Vp) and a positive relationship with volume transfer coefficient of contrast agent across the capillary wall (Ktrans).
Therefore, only the changes in pore volume with pore pressure are concerned in oil and gas engineering, so traditionally the pore volume compression coefficient of rocks is named as rock compression coefficient in oil and gas engineering.
These investigations reveal that with an increase in the pressure (and consequently the solubility of CO2 in oil), the volume swelling coefficient of the oil phase increases.
