Abstract:
An aqueous electroless nickel-phosphorous plating bath for forming an electroless nickel-phosphorous coating on an alkaline zincate coated substrate includes about 1.0 g/l to less than 5.0 g/l Ni, about 25 g/l to about 40 g/l hypophosphorous reducing agent; and 0 to about 120 g/l orthophosphite by-product. The electroless nickel-phosphorous bath with an orthophosphite concentration of up to about 120 g/l provides an electroless nickel-phosphorous deposit on the zincate coated substrate with an intrinsic stress that is more compressive than electroless nickel-phosphorous deposit provided using conventional electroless nickel-phosphorous baths.

Claim (Index 21):
A method of forming a disk for data storage, the method comprising:\n providing an aluminum disk, disposing an alkaline zincate coating over a surface of the aluminum disk; and contacting a zincate coated surface of the disk with an aqueous electroless nickel-phosphorous plating bath, the bath including about 1.0 g/L to less than 5 g/l Ni; about 25 g/l to about 40 g/l hypophosphorous reducing agent; about 20 g/l to about 30 g/l of at least one organic acid complexing agent, 0 to about 120 g/l orthophosphite by-product; wherein the electroless nickel-phosphorous bath with an orthophosphite concentration of up to about 120 g/l provides an electroless nickel-phosphorous deposit on the zincate coated substrate with an intrinsic stress that is more compressive than and a corrosion resistance that is superior in acidic media to electroless nickel-phosphorous deposit provided using similar electroless-nickel-phosphorous baths containing greater than 5.0 g/l Ni.
