For the service lives of, e.g., offshore structures, significance is attached not only to orrosive resistance but also to mechanical properties. Corrosion protection coatings on a ZnAl basis are often used for the protection of components subjected to loads. Suitable methods for post-treatment are necessary in order to implement improvements in the mechanical characteristics and corrosion protection effects of such coatings. In order to fulfil this purpose, “machine hammer peening” (MHP) was applied as the remachining process after the arc spraying of the corrosion protection coating in this research paper. The stipulated aims of this subproject (i.e. the implementation of low roughnesses and porosities as well as of high coating hardnesses and compressive residual stresses in the peripheral zone on the surface) were achieved by means of the MHP machining of the coated surfaces.
