  • Materials based on sialon's
    Publication number: 20070010392
    Abstract: Know Si3N4 and SiAlON cutting materials become, at the beginning, rounded very quickly on the cutting edge during usual long continuous cuts in gray cast iron (GG) which is described as initial wear. The invention thus provides that the raw material mixture of the material comprised of: component A, an alpha/beta SiAlON, and; component B, a hard material, has a composition consisting of 70 to 97% by volume of component A and 3 to 30% by volume of component B.
