| titleOfInvention | It is a kind of alkalinity tungstates passivating solution and be passivated chemical plating Ni-P coating method |
| abstract | The invention belongs to the technical field of metal material surface processing, a kind of disclose alkaline tungstates passivating solution and be passivated P layers of Electroless Plating Ni method.The alkalinity tungstates passivating solution is that the pH for using acid-base modifier to adjust passivating solution is prepared for alkalinity；The passivating solution includes sodium hydroxide, triethanolamine, tungstates, film forming accelerating and stabilizer component；Each component is a concentration of in the alkalinity tungstates passivating solution：3 20g/L of sodium hydroxide, 1 10g/L of triethanolamine, 10 60g/L of tungstates, 2 25g/L of film forming accelerating, 2 15g/L of stabilizer.The passivating solution composition of the present invention is simple, of low cost, safety and environmental protection；And passivated liquid processing gained passivating film, water white transparency have good resistance to metachrosis and corrosion resistance.The passivating solution is alkaline passivation liquid simultaneously, can avoid generating corrosive gas in work, corrode to equipment small. |
