摘要： A process for maintaining a continuous and stable aqueous nickel sulfamate electroforming solution adapted to form a relatively thin, ductile, seamless nickel belt by electrolytically depositing nickel from said solution onto a support mandrel and thereafter recovering said nickel belt by cooling said nickel coated mandrel effecting a parting of the nickel belt from the mandrel due to different respective coefficients of thermal expansion comprising: establishing an electroforming zone comprising a nickel anode and a cathode comprising said support mandrel, said anode and cathode being separated by said nickel sulfamate solution maintained at a temperature of about 140* to 160* F and having a current density therein ranging from about 200 to about 500 amps/ft2; imparting sufficient agitation to said solution to continuously expose said cathode to fresh solution; maintaining said solution within said zone at a stable equilibrium composition: Total Nickel 12.0 to 15.0 oz/gal Halide as NiX2.6H2O 0.11 to 0.23 moles/gal H3BO3 4.5 to 6.0 oz/gal ELECTROLYTICALLY REMOVING METALLIC AND ORGANIC IMPURITIES FROM SAID SOLUTION UPON EGRESS THEREOF FROM SAID ELECTROFORMING ZONE: CONTINUOUSLY CHARGING TO SAID SOLUTION ABOUT 1.0 TO 2.0 X 10 4 MOLES OF A STRESS REDUCING AGENT PER MOLE OF NICKEL ELECTROLYTICALLY DEPOSITED FROM SAID SOLUTION; PASSING SAID SOLUTION THROUGH A FILTERING ZONE TO REMOVE ANY SOLID IMPURITIES THEREFROM; COOLING SAID SOLUTION SUFFICIENTLY TO MAINTAIN THE TEMPERATURE WITHIN THE ELECTROFORMING ZONE UPON RECYCLE THERETO AT ABOUT 140* TO 160* F. at the current density in said electroforming zone; and recycling said solution to said electroforming zone.
