    Notes: Abstract The morphology of corrosion products formed on cobalt and nickel in argonoxygen-chlorine mixtures at 1000 K have been examined using optical microscopy, scanning electron microscopy, and X-ray diffraction. The corrosion products formed under conditions where the oxides are thermodynamically stable consist of porous oxides containing little or no chlorine. This morphology is consistent with a corrosion mechanism involving vapor phase transport of volatile metal chlorides.

    High-temperature oxidation of Fe-16.7% Mn-2.1% Ni-6.6% Si alloy in SO2 (1989)

    Notes: Abstract The oxidation of an austenitic Fe-16.7% Mn-2.1% Ni-6.6% Si (by weight) alloy in SO2 in the temperature range 600–900°C is described. The corrosion products formed on this alloy in this environment below 800°C consist only of oxides, rather than a mixture of oxides and sulfides as is observed for unalloyed Fe or Mn. The kinetics of oxidation of the alloy in SO2 in this temperature range are similar to those in O2. It is proposed that these characteristics result from the presence of a thin silicate layer near the scale-metal interface that alters the gradient of oxygen potential within the scale.

    Chemical reactions in mullite matrix SiC whisker reinforced composites in RF plasma (1997)
    Springer
    Journal of materials science 32 (1997), S. 523-528

    Notes: Abstract Decomposition of mullite by volatilization of SiO occurs during elevated temperature exposure to reducing gases. RF induction coupled argon plasma power sources have been used for rapid sintering of a number of ceramics and ceramic matrix composites. During plasma sintering of SiC whisker reinforced mullite matrix composites, whiskers were destroyed and the matrix converted to alumina by accelerated volatilization of silicon containing species. The results of these experiments are interpreted through the use of thermodynamic calculations of SiO pressures in the plasma environment.

    Friction and wear of single-crystal silicon at elevated temperatures (1991)
    Springer
    Journal of materials science 26 (1991), S. 1505-1511

    Notes: Abstract Single-crystal silicon wafers ((1 1 1) and (1 0 0)p-type) were abraded at room temperature 300 °C, and 600 °C by a polycrystalline partially stabilized zirconia ball in a ball-on reciprocating flat geometry. The sliding direction was 〈1 1 0〉. The friction coefficient was recorded as a function of reciprocating strokes and the deformation mode of the silicon. The friction coefficient at room temperature decreased with the number of strokes, and this variation was less affected by the number of strokes at the higher temperatures. The wear track width and depth were measured at the three temperatures. Wear increases as the temperature is raised to 300 and 600 °C. Optical and scanning electron microscopy of the subsurface damage reveals that cracks are generated at RT and 300 °C and dislocations are produced at 600 °C. The change in deformation mode with temperature from brittle fracture to plastic deformation accounts for the differences in wear.
