A comparative study on slurry erosion behavior of HVOF sprayed coatings

In actual work, slurry erosion behavior of three different HVOF sprayed cermet coatings has been studied. The coatings were developed using the powders feedstock having WC fine structured sizes, Cr3C2-NiCr 75-25 and NiCrWSiFeB, latter conventional grain sizes. The slurry erosion testing was performe...

The coatings were developed using the powders feedstock having WC fine structured sizes, Cr3C2-NiCr 75-25 and NiCrWSiFeB, latter conventional grain sizes. The slurry erosion testing was performed using a laboratory made pot-type slurry erosion tester, at an impact velocity of 3.61m/s and 9.33 m/s and impact angle of 30 and 90º. The mechanism of material removal in slurry erosion was studied and discussed on microstructural investigations and mechanical properties under the erosion conditions. It was observed that the WC-CoCr cermet coating with fine WC grain exhibits higher erosion resistance as compared to conventional cermet coating due to its improved properties like low porosity, high micro-hardness and fracture toughness.Este trabajo investiga el comportamiento del desgaste en mezclas erosivas de recubrimientos depositados mediante la técnica de proyección térmica usando el proceso HVOF. Se analizaron tres tipos de recubrimientos, WC-CoCr con estructura de grano fino, Cr3C2-NiCr 75-25 y NiCrWSiFeB, estos últimos con tamaños de grano convencional. Los ensayos de desgaste erosivo se desarrollaron usando un tribómetro de recipiente de mezclas para evaluar la resistencia a la erosión de los recubrimientos a velocidades de impacto de 3.61 m/s y 9.33 m/s y ángulos de impacto de 30 y 90º. El mecanismo de desgaste de los recubrimientos fue estudiado y discutido sobre la base del examen microestructural y la influencia de sus propiedades mecánicas. Se observó que el recubrimiento de carburo de tungsteno exhibe mejor resistencia a la erosión comparada con los recubrimientos de carburo de cromo y metálico debido a sus propiedades de microdureza, tenacidad a la fractura y menor porosidad.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).
