A powder can be produced by immersing microparticles (2) in a first solution (4) which contains coupling molecules (5), and then in a second solution (10) which contains the nanoparticles (12), thereby producing microparticles (2) with nanoparticles (12) attached thereto. The particles form powder particles (14) which allow nanoparticles (12) that are smaller than approximately 5 [mu] to be applied to a component by cold gas spraying.
