  • METHOD OF FORMING AN ALLOY COATING ON A STRIP
    Publication number: 20240158891
    Abstract: A hot dip method of forming an Al—Zn—Si—Mg alloy coating on a strip is disclosed. The method includes controlling the conditions in the molten bath to minimise the top dross layer in the molten bath. In particular, the method includes controlling top dross formation by including Ca and/or Sr in the coating alloy in the bath.
    Type: Application
    Filed: October 18, 2023
    Publication date: May 16, 2024
    Applicant: Bluescope Steel Limited
    Inventors: Michael Angel LOPEZ, Wayne Andrew RENSHAW, Andrew Vincent MICALLEF, Nega SETARGEW, Paul DONALDSON
  • METHOD OF FORMING AN ALLOY COATING ON A STRIP
    Publication number: 20210292872
    Abstract: A hot dip method of forming an Al—Zn—Si—Mg alloy coating on a strip is disclosed. The method includes control-ling the conditions in the molten bath to minimise the top dross layer in the molten bath. In particular, the method includes con-trolling top dross formation by including Ca and/or Sr in the coating alloy in the bath.

  • Spectroscopic Support
    Publication number: 20080291441
    Abstract: A porous sample support provides a matrix into the pores or interstitial spaces of which a sample to be subjected to a spectroscopic analysis can be introduced. 2 D infrared spectroscopy can then be carried out on the sample at higher concentrations with minimized background.

    Inventors: David Klug, Paul Donaldson
  • Method of Spectroscopy
    Publication number: 20080291444
    Abstract: A method of multidimensional spectroscopy has a controllable excitation source parameter and comprises controlling said controllable parameter to excite a vibrational mode of the sample, generating a homodyne reflected signal from the sample and obtaining a spectrum of the sample from the reflected signal.
