The corrosion fatigue behaviors of the creep-resistant magnesium alloys DieMag422 and AE42 were characterized by means of constant amplitude tests in sodium chloride solutions using corrosion potential and strain measurements. Characteristic microstructural deterioration and cracking processes in low and high cycle fatigue regime could be monitored on the basis of characteristic corrosion potential responses, which were investigated in detail by means of combined analysis of corrosion potential and total strain oscillations.

Hammer Peening

Thermally sprayed protective coatings are applied onto many mechanically stressed components such as support structures, shafts, turbine blades or heat exchangers. In addition to the static or cyclic load, a superimposition with corrosion processes occurs in many cases. Thermal sprayed ZnAl coatings are known for their performant corrosion protection properties. Within this context, the potential of ZnAl-based layer systems was analyzed regarding corrosion fatigue behavior. Therefore, a timeand cost-efficient testing strategy based on a corrosion-superimposed load increase procedure was used to estimate the effects of a corrosive attack during cyclic loading. The investigated coating systems were thermally sprayed and partially post-processed with a Machine Hammer Peening (MHP) operation. This treatment was identified as an appropriate technique for compressing and smoothing coated surfaces. The inter-relationships between the parametrization of the MHP process, the resulting surface integrity, and the estimated corrosion fatigue properties were analyzed. The investigations indicate a positive effect of MHP post-processing operations on the surface properties of the ZnAl-based coating system.
