摘要：A method for producing nozzles for injectors of internal combustion enginescomprising machining nozzle blanks, each having a cylindrical surface with first andsecond ends, a flat reference surface at the first end and a nozzle tip projecting from the

second end, applying a protective disc onto each flat reference surface, providing acontainment tube with a closed first end, sequentially inserting the nozzle blanks into thecontainment tube and completely filling a space delimited from an outer surface of thenozzle tip of the respective nozzle blank to an inner wall of the containment tube aftereach insertion, compacting the metal powder, evacuating a second end of the

containment tube, hot isostatic pressing the containment tube, cutting the containmenttube along cutting sections aligned with the protective discs to form separate sections,and machining the sections to form a metallic coating on each nozzle tip.
