Further studies should focus on evaluating the improvements caused by MHP. Therefore, it is necessary to adjust the test procedure. To differentiate the corrosion fatigue resistance of ZnAl coatings from each other, one approach could be to test under enhanced corrosion conditions. This could include pre-corrosion prior to testing or testing under constantly applied voltage between the specimen and reference electrode to enhance corrosion, which would be possible with the test setup presented (Fig. 2b).
