Claims (13)

  1. Verfahren zum Herstellen eines angestrichenen geformten Artikels, umfassend das Erhalten eines aus einer Aluminiumlegierung der 2000er oder 6000er Serie mit T4-oder T4P-Temperung geformten bogenförmigen Artikels; Formen des Artikels durch Biegen oder Prägen des Artikels unter Bildung eines nicht-planaren geformten Artikels; Auftragen von Farbe auf den geformten Artikel unter Bildung eines angestrichenen geformten Artikels; und, falls erforderlich zur weiteren Erhöhung der Härte des angestrichenen geformten Artikels und/oder zur Aushärtung der aufgetragenen Farbe, Brennen des Artikels bei einer Temperatur von zumindest 177°C; gekennzeichnet dadurch, daß der geformte Artikel einer thermischen Spiking-Behandlung vor dem Farbauftrag unterworfen wird, beinhaltend das temporäre Erhitzen des geformten Artikels auf eine Spitzentemperatur im Bereich von 150 bis 300°C.
  2. Verfahren gemäß Anspruch 1, dadurch gekennzeichnet, daß die Spitzentemperatur im Bereich von 150 bis 225°C liegt.
  3. Verfahren gemäß Anspruch 2, dadurch gekennzeichnet, daß das Erhitzen des geformten Artikels bei einer Geschwindigkeit im Bereich von 1 bis 70°C/min durchgeführt wird.
  4. Verfahren gemäß Anspruch 2 oder 3, dadurch gekennzeichnet, daß der angestrichene geformte Artikel dem Brennen bei einer Temperatur von zumindest 177°C unterworfen wird, um dessen Härte weiter zu erhöhen.
  5. Verfahren gemäß Anspruch 1, dadurch gekennzeichnet, daß die Spitzentemperatur im Bereich von 225 bis 300°C liegt.
  6. Verfahren gemäß Anspruch 5, dadurch gekennzeichnet, daß das Erhitzen des geformten Artikels durchgeführt wird mit einer Geschwindigkeit im Bereich von 10 bis 280°C/min.
  7. Verfahren gemäß Anspruch 5, dadurch gekennzeichnet, daß das Erhitzen des geformten Artikels durchgeführt wird bei einer Geschwindigkeit im Bereich von 210 bis 285°C/min.
  8. Verfahren gemäß irgendeinem der vorstehenden Ansprüche, dadurch gekennzeichnet, daß dem geformten Artikel das Abkühlen gestattet wird sofort nachdem er die Spitzentemperatur während der thermischen Spiking-Behandlung erreicht.
  9. Verfahren gemäß irgendeinem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß der geformte Artikel bei der Spitzentemperatur über eine Zeitdauer gehalten wird während der thermischen Spiking-Behandlung, bevor ihm gestattet wird, sich abzukühlen.
  10. Verfahren gemäß Anspruch 9, dadurch gekennzeichnet, daß besagte Zeitdauer bis etwa 5 Minuten beträgt.
  11. Verfahren gemäß irgendeinem der vorstehenden Ansprüche, dadurch gekennzeichnet, daß die thermische Spiking-Behandlung durchgeführt wird in einem kontinuierlichen Hitzebehandlungsofen.
  12. Verfahren gemäß Anspruch 11, dadurch gekennzeichnet, daß die thermische Spiking-Behandlung durchgeführt wird als Teil eines kontinuierlichen Form- und Anstreichverfahrens.
  13. Geformter Artikel, der zur Verwendung als Automobilteil geeignet ist, dadurch gekennzeichnet, daß der Artikel durch ein Verfahren gemäß irgendeinem der vorstehenden Ansprüche hergestellt wurde.
