Abstract
The invention provides a process for preparing a porous nickel-coated steel strip. The process comprises the following steps: a 5 to 10 mu m nickel-coated layer is deposited on a porous steel strip substrate; the steel strip is subject to low-temperature stress-removal treatment; and the porous nickel-coated steel strip is placed in a thermal treatment furnace for high-temperature crystallizing treatment. The nickel-coated porous steel strip prepared by adopting the process can effectively promote the corrosion resistance and chemical performance of the nickel-plated layer of the porous steel strip and improve the slurry performance of a battery because the low-temperature stress removal process is arranged before the crystallizing treatment.

Summary of the invention
The present invention aims to provide a kind of better mechanical property, can effectively improve the preparation method as the nickel-coated porous steel strip of the slurry performance of battery afflux liquid.
Realize the present invention through following scheme.
Employing thickness be 0.025～0.08mm, aperture be the porous steel strip of 0.5～1.5mm as base material, the nickel coatings in that its surface deposition thickness is 5.0～10.0 μ m after the operation of nickel deposited, carries out low-temperature prewarming earlier and handles, and carries out the high temperature recrystallization again and handles; The low temperature pretreatment condition does, under protective atmosphere or vacuum environment, temperature is 300～500 ℃, and the treatment time is 3～5 hours; High temperature recrystallization treatment condition do, under protective atmosphere or vacuum environment, temperature is 600～750 ℃, and the treatment time is 6～10 hours.
For making the galvanic deposit better effects if of base material, metal plating layer combines tightr with substrate layer, before said deposited nickel layer step, earlier the steel band base material is carried out oil removing, activation then.
Produce for adapting to, practice thrift cost, said protective atmosphere adopts the mixed atmosphere of being made up of reducing gas hydrogen and shielding gas nitrogen, and wherein the volume ratio of hydrogen and nitrogen is (1～5): 1.
Be the better strip material of obtained performance, the volume ratio of hydrogen and nitrogen is preferred 3: 1 in the said protective atmosphere.
Compared with prior art, advantage applies of the present invention in:
1, after the material process operation of nickel deposited, adopts the low-temperature prewarming treatment process, can not only effectively strengthen the bonding force between coating and the matrix, can also remove the hydrogen stress in the material structure effectively.
2, the material after handling through low-temperature prewarming being carried out the plated crystal recrystallization handles; Coating and matrix are interpenetrated and merge; Further refinement the grain structure of whole coating, improved the corrosion resistance nature of coating effectively, promoted the mechanical property of material simultaneously.
