Argonne National Laboratory (ANL) and the National Energy Technology Laboratory (NETL) are developing dense membranes for separating hydrogen from mixed gases, particularly product streams generated during coal gasification, methane partial-oxidation, and water-gas shift reactions. Hydrogen separation with these membranes is nongalvanic, i.e., it does not use electrodes or an external power sup...

A novel radio frequency magnetron sputtering method for the deposition of composite films which consist of chromium oxide and chromium ~Cr2O3/Cr-cermet! is presented. As an extension to conventional reactive sputtering of a Cr target in an argon and oxygen atmosphere the oxygen flow into the process chamber is switched periodically on and off. This leads to an oscillating oxygen partial pressur...

Abstract Titanium cermet combining metallic toughness with ceramic wear resistance has been proven to be a potential candidate for implanted joint material. In this work, titanium was synthesized by means of the elevated temperature solid carburizing technology. The Ti 13 Nb Zr alloy surface found converted into TiC layer combined carbon strengthened diffusion zone underneath. overall thickness...

as a high temperature structural ceramic, cermets exhibit less brittleness than ceramic-ceramic composites or monolithic ceramics owing to the presence of a ductile metal second phase in their microstructure. these cermets can, therefore, be used in applications where the abrasive, creep and thermo-mechanical resistance are required. in the present study, aluminum-alumina cermets with different...
