Zusammenfassung:A method of providing a plurality of cavities and/or apertures in a plate or layer wherein, after the plate or layer has been provided with a mask having a plurality of apertures arranged in a pattern, at least one jet of abrasive powder particles is moved relative to the plate. On its exposed surface, the mask is provided with a coating which prevents substantial mechanical stresses from being generated in the mask during the process by the jet of powder particles.
