Abstract
A method for the electroless coating of ferromagnetic substrates substantially free of microspheres or other unwanted auxiliary 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.
Claims21
A method of forming an electrolessly plated metal deposit on a ferromagnetic substrate comprising the step of demagnetizing the substrate prior to plating.
A method of making a combing device for yarn said device including a ferromagnetic member for combing said yarn including the steps of demagnetizing said ferromagnetic member and electrolessly plating a metal coating thereon.
A method for obtaining a smoother electrolessly metallized ferromagnetic substrate comprising the step of demagnetizing the substrate prior to the step of electroless metallization.
