发明名称 Method of electroplating a nickel-iron alloy film with a graduated composition
摘要 In the NiFe electroplating method of the present invention, the atomic percent (at. %) composition of Ni and Fe in NiFe electroplated material is controlled by selection of the duty cycle of the electroplating current during the electroplating process. Generally, for a particular electroplating bath, where the electroplating current duty cycle is greatest the NiFe electroplated material has a higher Fe at. %, and where the electroplating current duty cycle is reduced, a lower Fe at. %. Therefore, electroplated NiFe components from a single electroplating bath can have differing NiFe concentrations where the electroplating current duty cycle is altered. Additionally, NiFe components can be electroplated with a graduated or changing Ni and Fe concentration by altering the electroplating current duty cycle during the electroplating process.
