Abstract
A method for the electroless coating of ferromagnetic substrates substantially free of microspheres or other unwanted auxillary matter, thereby reducing the roughness of the coated articles. The method and articles produced are subjected to a magnetic field and demagnetized prior to the plating step. The method is of particular utility in the coating of textile machinery parts operating at high rotational speed in the minimizing of dust and yarn damage. The method is also of great utility in the deposition of composite electroless coatings.
