- the phosphatability was determined by scanning electron microscope images. Thus, a "+" - in Table 3, a closed, finely crystalline phosphate layer, an "o” a closed, coarsened phosphate layer (crystals with> 20 ⁇ edge length) and a "-" a non-closed to nonexistent phosphate layer.
- Comparative Example VB1 reveals that owing to an excessively high Zr support weight, the layer obtained in the treatment according to step c) (37 mg / m 2 at AA 5754 and 26 mg / m 2 at AA 61 1 1) has very high volume resistivities - in particular a storage of 30 days - be obtained (100 ⁇ -ohms for AA 5754 and 38 ⁇ -ohms for AA 61 1 1).
- examples B1 to B7 show that, in compliance with the conditions essential to the invention, with regard to the type of pickling treatment, the Zr / Mo ratio, the produced coating weight, the respective Concentration and pH ranges of the treatment solutions layers with extremely good volume resistances at the same time good adhesive properties are obtained.
- the pretreated test slides of Examples B6 and B7 and a non-pretreated bare test slide VB6 were further subjected to a multistage anticorrosive treatment consisting of the following steps: i) Alkaline purification (60 ° C., 180 s)
- the corrosion protection of B6 and B7 is similar to that of VB6.
- the pretreatment according to the invention therefore does not adversely affect the protection subsequently achieved by a corrosion-protective treatment.
