Cobalt germanides have been widely studied as semiconductor contact materials, but recent theoretical studies suggest that they may also be excellent catalysts for methane steam reforming with stabilities and activities comparable to noble metal catalysts. In order to study the catalytic activity of cobalt germanides, it is critical to first...
This paper is a metallurgical study of the microstructure of a
cobalt base hard facing alloy to determine the cause for inconsistant
wear properties. Wear tests on a Stellite 6 alloy, deposited using
oxyacetylene welding techniques, resulted in a wide range of weight
losses.
Microscopic examination has revealed the probable...
