Thermal spraying has been developed as an advanced coating process, which allows the generation of nonequilibrium microstructures due to it's high cooling rates. Recently, this process has become of growing interest in industrial applications. The microstructure of three Fe-Cr-based coatings deposited by Twin Wire Arc Spraying (TWAS) and High Velocity Oxygen Fuel (HVOF) process has been investigated by XRD, TEM and SEM and has been found to contain nanocrystals of about 20 nm in diameter. Characteristic differences in microstructure can be found in porosity and oxide content due to different particle velocities in both coating processes. The application of these coatings is dependant on the knowledge of the mechanical design parameters such as Young's modulus, yield stress, ultimate tensile strength (UTS) and fatigue behavior. These values have been investigated in a static and a dynamic three-point-bending test. It has been found, that the porous TWAS sprayed FeCrl3 coating has an effective elastic modulus in the range of bulk Al-alloys whereas dense HVOF coatings show nearly the expected value of cast iron alloys.
