    摘要: The invention relates to a Tungsten Carbide coated coating doctor blade used for the coating of paper and board. The doctor blade comprises:
    a substrate in the form of a strip,
    a wear resistant top deposit covering the working edge of the blade intended for being in contact with the moving web,
    the wear resistant top deposit comprises WC particles in a Ni-based matrix,
    the Ni-based matrix comprises in weight %:
    Cr 1-32
    Mo 1-32

    optional components, balance Ni and impurities.
