Additive Manufacturing of Silicon …

Silicon carbide (SiC)‐based materials are needed for a nuer of high temperature appliions due to their excellent strength, thermal stability, and oxidation resistance. Fabriion of functional SiC ceramics by additive manufacturing technologies greatly reduces production time and cost, particularly for small production quantities necessary for prototype development.

Thermal decomposition of nickel carbide: an …

A carbon Auger spectrum indiive of nickel carbide is detected in thin films of nickel evaporated onto graphite in ultrahigh vacuum. Isothermal heating of the films leads to an irreversible change in the carbon Auger lineshape. This change is interpreted as evidence for the decomposition of the nickel carbide. Initial and final spectra are representative of carbide and graphite, respectively.
