  • Method of preparing aluminum memory disks
    Patent number: 5437887
    Abstract: A method is provided for producing paramagnetic electroless nickel-phosphorus (ENP) coatings on zincated aluminum substrates using an ENP bath containing antimony and/or cadmium ions and/or an adjusting operating pH, which coated substrates have enhanced retention of their paramagnetic properties after being exposed to elevated temperatures on the order of 310.degree. C. as, for example, when the ENP coated substrate is further treated by sputtering operations to form another metal layer on the coated substrate to produce magnetic memory disks.
