Wear mechanisms of WC–Co cutting tools from high-speed tribological tests

Abstract: a b s t r a c tIn machining processes, surface roughness and dimensional accuracy of machined parts depend on tool wear. Cemented carbide based cutting tools remain widely used in machining processes for their wear resistance. The aim of this paper is to study wear mechanisms of a WC-Co cutting tool grade under tribological conditions. Dry friction experiments are carried out on a high-speed pin-on-disc tribometer considering WC-Co pins against steel discs made of an AISI 1045 grade. Furthermore, two type-K th… Show more

“…Figure 9 demonstrates the wear volume of the non-irradiated and irradiated WC-Ni samples following the tribo-tests. The average wear volumes of the non-irradiated YN6 and YN10 surfaces were of approximately 5e-3 mm 3 . Consequently, the average wear volumes of the irradiated YN6 and YN10 surfaces reached 6.6e-3 and 7.4e-3 mm 3 , respectively.…”

“…Por otra parte, el material APS presenta un comportamiento irregular en el coeficiente de fricción durante el ensayo, que no es observado con la misma magnitud en el resto de materiales. Este comportamiento puede ser debido a la alta porosidad presentada en el recubrimiento APS que induce a vibraciones de baja frecuencia en el tribómetro [130].…”

“…Kagnaya et al [101] confirma que para ensayos de fricción a bajas velocidades de WC-Co contra AISI 1045, el mecanismo de desgaste predominante es deformación plástica y micro agrietamiento de los granos de WC, fragmentación y pérdida de adherencia de los granos de WC y pulido de la superficie de contacto.…”

“…Los valores promedios del coeficiente de fricción se encuentran en el rango de 0.58-0.83. Este comportamiento es típico en carburos cementados cuando son evaluados contra acero y ha sido observado por diferentes autores [24,46,101,104,124].…”
