Electron Beam Technology - Electron Beam Surface Treatment

Electron Beam Surface Treatment

The modern electron beam welders are usually provided with computer controlled deflection system, which can position the beam very fast and accurate over the selected area of the work-piece surface. Thanks to the high speed of heating, only a thin surface layer of the material is influenced, e.g. for "hardened", annealing, tempering, texturing, polishing(with argon gas present) etc. If the electron beam is used to cut a shallow trough in the surface, then repeatedly moving horizontally along the trough at high speeds it creates a small pile of ejected melted metal at the end of the trough, Upon repetition spike structures can be created up to a millimeter high. These can aid bonding between different materials and modify surface roughness of the metal.

Famous quotes containing the words beam, surface and/or treatment:

    What do we plant when we plant the tree?
    We plant the ship that will cross the sea,
    We plant the mast to carry the sails,
    We plant the planks to withstand the gales—
    The keel, the keelson, and beam and knee—
    We plant the ship when we plant the tree.
    Henry Abbey (1842–1911)

    When we are in love, the sentiment is too great to be contained whole within us; it radiates out to our beloved, finds in her a surface which stops it, forces it to return to its point of departure, and it is this rebound of our own tenderness which we call the other’s affection and which charms us more than when it first went out because we do not see that it comes from us.
    Marcel Proust (1871–1922)

    The treatment of African and African American culture in our education was no different from their treatment in Tarzan movies.
    Ishmael Reed (b. 1938)
