Conversion layers (oxide containing chromat and phosphate layers) on aluminium and its alloys are notable for their considerable corrosion resistance. Depending on process control they show smooth or rough closed layers which provide an excellent adhesive base for organic coating systems1,2. The adhesion with the organic coating is so firm that difficult bending, profiling and other forming operations can be carried out without problems.
