High-Temp Details • Precision Metal Spinning
HIGH-TEMP ALLOYS Also called superalloy or high-performance alloy is an alloy with the ability to operate at a high fraction of its melting point.Several key characteristics of a superalloy are excellent mechanical strength resistance to thermal creep deformation good surface stability and resistance to corrosion or oxidation. The crystal structure is typically face-centered cubic (FCC)

The current (first generation) thermal insulation layer is composed of 7wt yttria-stabilized zirconia (7YSZ) with a typical thickness of 100–300 µm. Yttria stabilized zirconia is used due to its low thermal conductivity (2.6W/mK for fully dense material) relatively high coefficient of thermal expansion and good high temperature stability.

Nov 01 2017 · The diameter and shell thickness of the carbon nanospheres prepared with (C 2 F 4)n are approximately ∼50-200 nm and ∼10-20 nm respectively (Fig. 11d). We assume that the size difference between the hollow spheres can be related to the combustion temperature which is 2023 K and 1590 K for (C 2 F 4) and (C 2 H 3 Cl)n
