pH 4.4-5.2
Wherein, single nickel salt preferably: 25 grams per liter plating baths; Inferior sodium phosphate is 30 grams per liter plating baths preferably.
The present invention has the following advantages owing to adopted above-mentioned design:
1, owing to added the amino acids accelerator, makes by the surperficial autocatalysis ability of plating material obviously to strengthen during the present invention fills a prescription, and the activation energy of chemical nickel plating reaction is greatly reduced, therefore sedimentation velocity is significantly improved, can reach more than 25 microns/hour.
2, be complexing agent with the organic carboxyl acid compounds, not only improved the stability of plating bath, when itself and amino acids share, plating speed is obviously improved, and the quality of coating is obviously improved, the phosphorus content height of coating, the coating phosphorus content is greater than 10% (weight ratio), and coating is the strong non-crystalline state of solidity to corrosion, simultaneously, can improve phosphorous acid nickel set point, play the effect of stablizing tank liquor.
3, use inorganic iodide to be stablizer, make the coating that obtains with heavy metal salt and sulfocompound as stablizer gained coating bright corrosion resisting more, and bath stability is better, stability is greater than 7 cycles.
The present invention will be further described below in conjunction with specific embodiment.

Adding distil water to 1000 milliliter
pH 4.8
Two, the preparation of nickel-plating liquid
1, takes by weighing single nickel salt and the inferior sodium phosphate and the dissolving respectively of metering;
2, take by weighing the metering lactic acid dissolution after, being neutralized to pH with ammoniacal liquor is about 5, other adds in the above-mentioned nickel sulfate solution after taking by weighing metering sodium-acetate dissolving;
3, with after Padil and the potassiumiodide dissolving, add in the ortho phosphorous acid sodium solution, be added to while stirring then in the container that fills nickel sulfate solution, this moment, water temperature was no more than 60 ℃;
4, transfer pH to 4.8 with ammoniacal liquor, add the water constant volume.
Three, chemical nickel plating
In temperature is that 88 ℃-95 ℃, surface to volume ratio are 0.9-1.4dm
2Under the condition of/L, workpiece is soaked in carries out chemical nickel plating in the above-mentioned plating bath, the time of immersion requires to decide according to the difference to coating.This plating bath is applicable to the chemical nickel plating processing of material surfaces such as various metals, plastics, pottery, diamond.
Detected result according to porosity shows that along with thickness of coating increases, porosity reduces gradually, and when thickness of coating was 20 microns, porosity was about 0.4/centimetre
2, as seen in order to guarantee that having certain corrosion resisting property should make thickness of coating more than 20 microns.
Four, the mensuration of the every index of gained coating
1, solidity to corrosion
(1) the anti-concentrated nitric acid experiment of coating is 160s (18 ℃ of temperature).
(2) immersion test shows, the solidity to corrosion of coating in various media is better than the 1Cr18Ni9Ti stainless steel, and best with solidity to corrosion in alkaline environment, as shown in table 1 especially:
The solidity to corrosion of table 1 coating
Medium coating 1Cr18Ni9Ti
5% sodium-chlor 4.28 * 10
-3Mm/a-
10% sulfuric acid 6.40 * 10
-2Mm/a＞1.5mm/a
10% sodium hydroxide 2.96 * 10
-3Mm/a＜0.05mm/a
2, hardness and wear resistance
Coating is carried out 400 ℃, 1 hour and 280 ℃, 8 hours processing, its Vickers' hardness and wear resistance see Table 2, by in the table 2 as seen, 280 ℃, 8 hours heat treated coating hardnesses and durionise are on close level, and the wear resistance of plated state coating also is on close level with the plating hard nickel, has high hardness and wear resistance.
Table 2 hardness and wear resistance detect
