<p>Permanent cobalt alloy magnets of large size are prepared. At least two compacts of particulate permanent magnet cobalt alloy are provided and a layer of particles of a bonding magnetic cobalt alloy agent is deposited on the bonding surface of one compact. The bonding surface of the second compact is contacted with the deposited bonding agent substantially coextensively therewith and the resulting assembly is sintered to produce a sintered bonded composite. At least 1% by volume of the bonding agent passes through a liquid phase at an elevated temperature.</p> |
