  • Flux Coated / Stick
    and molten weld pool. The flux also forms a slag that protects the cooling weld pool or braze joint. The slag must be chipped or brushed off the weld bead after welding. The flux coating also provides a method of adding scavengers, deoxidizers, and alloying elements to the weld metal.
  • Advantages of Non-Electrolytic formed Aluminum Oxide Coating
    attack on the metal by the deoxidizer. Many of the. deoxidizers now in use will use an iron (III) salt, such as ferric sulfate coupled with hydrogen peroxide,3 or any. one of a number of different oxidizers (chlorates, nitrates, persulfates, etc.). Iron based deoxidizers leave deposits. of iron
  • An Overview of Non-hexavalent Chromium Conversion Coatings for
    . This allows for the oxide to. be removed rather than having a direct attack on the metal by the deoxidizer. Many of the deoxidizers now in use will run an iron (III) salt, such as ferric sulfate coupled. with hydrogen peroxide,4 or any one of a number of different oxidizers (chlorates, nitrates
  • The importance of using conversion coatings
    is the removal of oxides and other inorganics that would interfere with further processing. without significant attack on the aluminum surface.1 Deoxidizer use is generally restricted to alloys. containing 2 percent or more heavy metals, such as zinc or copper. To prevent excessive attack
