PROPERTIES OF HARD ALLOYS SINTERED FROM METALLIC CARBIDES

Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1

Abstract

The TiC or TaC alloys, the simple WC-C0 alloys with the same cobalt content are much more resistant to bending and breaking and feature improved electrical and heat conductivity. The oxidation resistance of the simple WC-C0 alloys is considerably lower which results in a pregnant tendency for chip welding and low resistance. Hardness is affected by micro- porosity, granulation of WC phase, purity and composition, extent of homogenization of the liquid and carbons. The magnetic saturation increases with higher Co contents; it is worth mentioning that bigger grain alloys have a force considerably lower than that of fine grain ones.
