Caracterización morfológica de polvos cerámicos para la fabricación de recubrimientos termorrociados

The  properties  of  the  ceramic  coatings  are not  only  affected  by  the  electrical  parameters  associated  with  the deposition,  but  are  also  influenced  by  the feed material. Characteristics as constituent elements, morphology, phase and particle size distribution of ceramic powders, and influence roughness and surface quality of coatings, as well as in the porosity, hardness and toughness thereof.  Based on the above, the following study is based on the characterization of Tungsten Carbide (WC-12%Co) and Alumina-Titania (Al2O3-13%TiO2); systems used in obtaining thermal sprayed coatings. To do this, its chemical and morphological characteristics were evaluated using X-ray diffraction, Optical Microscopy and Scanning Electron Microscopy with EDX, which the morphology and size distribution were relating with the microstructural properties such as porosity and microhardness  of  coatings  obtained  from  these  ceramic systems.
