Description
(1) technical field under
The present invention relates to a kind of method that is used for the chemical plating Mi-P alloy of stainless steel surface, belong to the processing method of a kind of stainless steel chemistry plating.
(2) background technology
Stainless steel surface has the passive film of one deck densification, thereby has good solidity to corrosion, uses very extensive.But stainless steel surface often exists some to destroy the inhomogeneity defective of passive film, and is comparatively weak at these local passive films as inclusion, poor chromium district, crystal boundary, dislocation etc., some active anions such as Cl
-, SCN
-Enter stainless steel surface Deng easily from fault location, destroy its passive film, thereby stainless solidity to corrosion is weakened greatly; Stainless hardness is on the low side, and its wear resistance is good inadequately, and these defectives have also limited stainless Application Areas.Chemical plating Mi-P alloy coating has good acid-and base-resisting and brine corrosion.High phosphorus chemical plating Ni-P alloy layer has good solidity to corrosion, particularly has good anti-Cl
-Corrodibility; Low-phosphorous electroless plating has higher hardness and good wear resistance; In addition, " the imitative type " of electroless plating makes that also the application of electroless plating is increasingly extensive.Therefore, carry out electroless plating, can improve stainless use properties, enlarge stainless Application Areas at stainless steel surface.Because of stainless steel surface has the passive film of one deck densification, thereby make the very difficulty of carrying out the electroless plating change on its surface.
But since stainless inertia, present chemical plating technology, the mechanical property of its coating is not high, and is relatively poor with stainless bonding force, and technology is complicated.
(3) summary of the invention
The present invention provides a kind of method that is used for the chemical plating Mi-P alloy of stainless steel surface in order to overcome the deficiency of above technology, and this processing method is simple, and the physical strength height of coating is with good relatively poor of stainless bonding force.
The present invention realizes by following measure:
Solvent degreasing (chloroform or acetone, 1～2min soak) → washing (room temperature, 2min soak) 1 → alkali lye oil removing (Na

2, 5min) → washing (room temperature, 2min, soak) 4 → in and 1 (15% ammoniacal liquor, room temperature are soaked, 1min) → pure water (or distilled water) washing (30 ℃ are soaked 2min) 5 → chemical nickel plating (2h) → washing (room temperature, soak, 1min) 6 → in and 2 (8～10% NaOH alkali lye, room temperatures, soak, 1min) → (room temperature is soaked, and 2min) 7 → moisture drying is (80 ± 10 ℃ in washing, 10min) 1 → dehydrogenation (thermostatic control, 190 ℃, 1h) → passivation sealing of hole (chromating method, 10min, soak) → washing (room temperature, soak, 2min) 8 → moisture drying (80 ± 10 ℃, 10min) 2 → service check.
Technological process of the present invention can generate the very firm chemical plating coating of a kind of bonding force at stainless steel surface.Can select low-phosphorous chemical nickel plating, middle phosphorus chemistry nickel plating or high phosphorus chemical plating nickel according to the application need of coating.Coating has good glossiness, and apparent very fine and smooth, feel is soft and smooth, and color and luster is silvery white.
(4) embodiment
In order to guarantee the stainless steel surface deoiling effect, adopt two kinds of oil removing operations such as organic solvent and alkali cleaning.Organic solvent adopts acetone (or chloroform), and 1～2min soaks, then the 2min of water elder generation at room temperature.The alkali lye of alkali lye oil removing is common degreaser, with the process water preparation, adopts Na
2CO
3, Na
3PO
412H
2The mixed solution of O, NaOH, OP-10, temperature: 80 ± 5 ℃, the time: 20min.Wash after the oil removing thoroughly, adopt about 30 ℃ Warm Wash earlier, then with the room temperature washing, activate after the twice washing, activation solution is the mixing acid of sulfuric acid and hydrochloric acid.Carry out flash nickel then, carry out technology controlling and process by Woods nickel preplating method, current density is 2A/dm
2Washing is immersed in 15% ammoniacal liquor and neutralize afterwards, carries out electroless plating then.
Wash with pure water or distilled water before entering electroless plating tank.Chemical plating fluid can be selected low phosphor bath, high phosphor bath or middle phosphor bath for use according to the coating performance needs.The time of chemical plating Mi-P alloy can be controlled according to required thickness of coating situation, and general 2h should note adding and thermostatic control of reagent in the electroless plating process.Should neutralize after the electroless plating washing, adopt 8～10% NaOH sig water.In the electroless plating process, H is arranged
2Produce, will carry out dehydrogenation after the electroless plating and handle, in constant temperature oven 190 ℃, 1h.In order to make film fine and close more, adopt the passivation hole-sealing technology, this process using be the chromating method, for environmental protection production, the chromium-free deactivation method is adopted in suggestion.
