Beams of a hardenable aluminium foam were coated using electric arc spraying. AlSi6 and XCr13 were sprayed using compressed air or nitrogen. Subsequently the aluminium foam – coating - composites were post treated. The post treatment comprised of a heat treatment, suitable for hardening of the foam, grinding, shot-peening and / or sealing of the coating. Young’s moduli of the composites were non-destructively measured by resonant frequency. The dynamic properties of the composites were investigated by four-point-bending fatigue tests. The influence of the different post treatments on the bending stiffness and the fatigue behaviour was analysed using a statistical approach.
