| titleOfInvention | Phosphorus-free, nitrogen-free, chromium-free stainless steel passivation solution |
| abstract | The present invention relates to the technical field of stainless steel surface treatment, and more particularly, the present invention provides a phosphorus-free, nitrogen-free, chromium-free stainless steel passivation solution, in terms of mass percentage, the preparation raw materials at least include 1-5% oxidant and 1-5% film-forming agent , 3-10% complexing agent, 0.01-0.2% penetrating agent, 0.5-2% film-fixing agent, and the balance is deionized water; the film-fixing agent is a dicarboxylic acid salt with 8-13 carbon atoms . The phosphorus-free, nitrogen-free, chromium-free stainless steel passivation solution provided by the invention can form a stable corrosion-resistant organic complex passivation film on the surface of martensitic stainless steel, has good film-forming effect and strong compactness, and can be used in salt solution, It has good corrosion resistance retention under heating, acid environment and pressure steam, which can prolong the service life of martensitic stainless steel. |
