| titleOfInvention | A kind of Aluminum Alloy Room Temperature alkalinity chromium-free passivation liquid and passivating method |
| abstract | The invention belongs to the technical fields of metal material surface processing, disclose a kind of Aluminum Alloy Room Temperature alkalinity chromium-free passivation liquid and passivating method.The alkalinity chromium-free passivation liquid is to adjust the pH of chromium-free passivation liquid by acid-base modifier to obtain to alkalinity；The chromium-free passivation liquid is made of molybdate, complexing agent, oxidant, film forming accelerating, surfactant and water.Aluminium alloy is carried out alkali cleaning oil removing scale removal by the passivating method first；Acid-wash activation again after cleaning；Normal temperature passivated processing is carried out after cleaning again, and washes drying or drying, obtains aluminium alloy passivating film.Passivating film growth is rapid, has good resistance to metachrosis and corrosion resistance.The passivating solution each component chemical property of the present invention is stablized, and storage and transportation is convenient for, and technological operation is easy, of low cost, and room temperature processing is energy-efficient, it is easy to accomplish industrialization. |
