Popis: | This study aims to review in situ corrosion tests and evaluated some characteristics of complex composite layers based on powders Ni21Cr11Al2.5Y1Co with 3%WC. These powders presenting agglomerate WC man-sized cluster particles and are used as an option for coating geothermal carbon steel omponents to prevent extensive erosion-corrosion fen omen. The powders are used to protect steel components by multilayer thermal spraying HVOF deposition. The experimental procedure involved obtaining X-ray diffraction patterns of the specimens, profilometry images of erosion-corrosion tests and SEM investigation to provide detailed information about adhesion of protective layers and morphological modifications. |
