Microstructure Characterization of Superfine WC-Co Powders

Abstract:

In this paper results of tests concerning the WC/Co fine-crystalline composite powders type 88/12 and 83/17 provided for thermal spraying of layers resistant to abrasion are presented. Tests which characterize basic technological properties were performed since these properties are essential from thermal spraying point of view. Microstructural properties are essential as well because they allow evaluation of morphology of powders by SEM method with an analysis of chemical composition in micro-areas. Moreover, the phase composition was characterized by XRD in macro scale and by EBSD in microareas including distribution maps of individual phase components in all particles of the powders.
