<PICT:1026246/C6-C7/1> To provide on an aluminium wire 1 with an insulating layer followed by a conductive layer on which is formed an anisotropic layer of magnetic material, the wire 1 passes first through an anodising stage 7 and sensiting tanks 9 and 11 containing respectively Su Cl2 and Pd Cl2, then has a layer of nickel, copper or gold deposited on it in an electroless stage 13 and is finally provided with a coating of nickel/ion alloy in an electroplating stage 15. Each operation is preceded by a water rinse and the plated wire is dried at 23. The heavy current which provides the orienting field during electroplating is passed through the wire 1 from source 24 while the plating current is supplied from source 21 through the nickel, copper or gold layer. |
