Abstract

Es wird ein Verfahren zum pulvermetallurgischen Herstellen eines Cu-Cr-Werkstoffs für einen Schaltkontakt, insbesondere für Vakuumschalter, bereitgestellt, mit den Schritten: (S2) Pressen eines aus Cu-Pulver und Cr-Pulver gebildeten Cu-Cr-Pulvergemischs, (S3) Sintern des gepressten Cu-Cr-Pulvergemischs zu dem Werkstoff des Cu-Cr-Schaltkontakts. Das Sintern oder ein nachfolgender thermischer Behandlungsprozess wird mit einem alternierenden Temperaturprofil durchgeführt, bei dem das Cu-Cr-Pulvergemisch bzw. der Cu-Cr-Werkstoff zumindest zweimal abwechselnd über einen oberen Temperaturgrenzwert erwärmt (S4) und wieder unter einen unteren Temperaturgrenzwert abgekühlt (S5) wird. Sämtliche Schritte werden bei Temperaturen durchgeführt, bei denen sich keine schmelzflüssige Phase ausbildet.
