Abstract: The present invention relates to a process for the repair and restoration of dynamically stressed components comprising aluminium alloys for aircraft applications in which (a) the base material from which the component to be repaired was manufactured is determined, (b) the component to be repaired is, if necessary, subjected to pre-treatment, (c) a spray material which has chemical, physical and mechanical properties comparable to those of the base material is selected, (d) coating parameters for the subsequent coating process are selected so that bonding within the layer to be applied is optimized, (e) the spray material is applied to the component to be repaired by means of cold gas spraying in order to replace material which has been removed by wear and pre-treatment, and (f) the coated component is after-treated in such a way that the original component geometry is restored.
