| Abstract: |
| The paper compared and introduced the characteristics and application of the surface treatment technology which is commonly used for metal bonding and emphatically discussed the process principle of PAA. With typical PAA line in domestic aviation manufacturing enterprises as an example, phosphoric acid anodizing process production line was introduced in detail from hanging method, alkali cleaning, solid processing, anodized parameters, such as water cleaning, key control points on application in the actual production process of PAA process were analyzed, in order to provide reference to the development of phosphoric acid anodizing technology for aviation aluminum alloy surface. Finally, it put forward that the realization of green environmental protection requirements of energy saving in the full life circle of PAA production line is a common research problem to be jointly solved by domestic academia and industry. |
