“…The surface tension of liquid iron has been found to be approximately 1900 mN/m by a number of investigators in the past, [8,9,10] which is very close to the value determined in the present study. Table II, which lists the surface tensions of liquid nickel measured in the past, [10][11][12][13][14][15][16][17][18] illustrates the disagreement among previous researchers. The present data for pure nickel are in reasonable agreement with those of Keene et al, [13] Popel et al, [14] and Lee et al [15] but is substantially lower than the value determined by Fraser et al [12] B…”

“…Swelling of nickel droplets in contact with alumina substrates has been reported earlier. [14] It is possible that liquid nickel reacts with the alumina substrate in these extremely reducing conditions to form a very stable spinel with the evolution of carbon monoxide. The sessile drop experiments were then successfully carried out on magnesia substrates, and no reaction between the two phases could be detected.…”

Surface tensions of iron-nickel alloys were measured as a function of oxygen potential at 1550 ЊC using the sessile drop technique. The surface tension of pure liquid nickel and iron-nickel alloys was measured at a total pressure of 1 atmosphere under varying CO 2 /CO ratios. An increase in the oxygen potential in the gas phase was found to correspond to a decrease in surface tension of pure nickel and iron-nickel alloys, indicating that oxygen is surface active in both liquid nickel and iron-nickel alloys. At low oxygen potentials, nickel additions to liquid iron were found to cause small decreases in alloy surface tensions; however, at higher oxygen potentials, the surface tension of the alloy exhibited a minimum value as nickel was added to iron. The adsorption coefficients of oxygen in liquid iron-nickel alloys and pure liquid nickel were determined from the surface-tension data using Belton's analysis, and were found to be similar to those calculated from kinetic studies. Wettability of iron-nickel alloys on an alumina substrate was studied through contact-angle measurements. At a constant alloy nickel content, the contact angle between the alloy and alumina decreased with increased oxygen potential in the gas phase.

“…SEM analyses were performed after wetting experiments with the metallic iron and the ceramic samples. Popel et al had observed a decrease in contact angle of up to 3° by an increase of carbon content from 2 to 5 wt% in Fe‐C binary alloys. This has been justified by the formation of CO bubbles at the Fe‐C/Al 2 O 3 interface.…”

The effect of temperature, atmosphere, and elemental concentrations of boron and phosphorous in ferrous alloys on the wettability of polycrystalline α‐Al2O3 was studied. The investigation of the wetting behavior is of major importance to the infiltration of steel into open foam ceramics. In reference Fe‐0.46 wt% C iron samples, the contact angle was investigated between 1550 and 1650 °C under Ar‐H2 and Ar atmospheres and was found to decrease with increasing temperature and increasing oxygen partial pressure. Furthermore, no FeAl2O4 (hercynite) spinel type inclusions were found in Fe/Al2O3 experiments. In the Fe‐P binary alloys, θ decreased with increasing phosphorous content and was ≈112° for the Fe‐0.299 wt% P alloy at 1600 °C. For the Fe‐B binary alloys, a strong influence of boron on the contact angle was found. Secondary neutral mass spectrometry (SNMS) analysis showed a maximum in the boron concentration in the first 50 nm of the metallic side of the interface. In the FeCrMnNi‐P high‐alloys specimens, a reaction layer was found between the steel/ceramic interfaces. The contact angle was ca. 90°, lower than the Fe‐P binary alloys.

“…Compared to abundant density data of pure Ni [4][5][6][7][8], data for density and solidification shrinkage of Ni-Cr alloys in mushy state is rare because of difficulty in controlling oxidation of Ni-Cr alloy at high temperature. With exception of a few authors [9][10][11], the data on the density of Ni-Cr alloy in mushy state was only measured by Kato et al [2] with sessile drop method and the * Corresponding author.…”
