ABSTRACT:
A method of manufacturing an electro-magnet, comprising two tubular poleshoes which are coaxially arranged with respect to each other and in which an armature is slidable, the inner surface of the poleshoes and the outer surface of the armature being successively degreased and pickled, after which they are provided with a nickel layer by electroplating, and a nickel phosphide layer formed by electroless deposition of a nickel-phosphorus layer which is converted to nickel-phosphide by heating to about 400.degree. C. The electromagnets manufactured by means of the method in accordance with the invention are particularly suitable for us in matrix printers.
