Pickling and Passivation Technology for Automobile Aluminum Parts
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 1
Abstract
To improve the pickling and passivation process quality of aluminum part before body welding, this paper introduced the pickling and passivation process and common quality problems of aluminum parts before welding, as well as the pickling and passivation process and wastewater treatment technology. The paper provided effective solutions based on practical production. Electrophoresis film quality defects of aluminum parts caused by residual oil were eliminated by optimizing degreasing process. Combined with electrophoresis coating quality and the surface resistance of aluminum, Ti-Zr coating process can’t be found on the surface of aluminum parts before pickling and passivation.
