Intrusion bonding of nickel to zirconia was achieved by hot pressing the zirconia powder onto Ni sheet, at pressures of about 55 MN/m2, and temperatures of about 1573 K. The intrusion zone can be several hundred micrometers thick, providing a gradual transition from ceramic to metal The most extensive intrusion occurred when pressure was applied late in the heating cycle, after the zirconia powder had coarsened. The parameters determining the extent of the intrusion bonding are discussed. The intrusion bonds are compared to diffusion bonds for which a discrete metal/ceramic interface was maintained. Vickers micro-indentation tests in the intrusion bond zone indicated that metal intrusion provided improved bonding.
