  • Round metallic balls for example made of lead (and known as “shot”), may be used.
  • Shot peening which is a cold working process conventionally used to produce a compressive residual stress layer and modify the mechanical properties of metals and composites, is particularly preferred.

  • This anti-corrosion layer also hides the original surface color of the elements which may be more reflective or otherwise visible if paint is scratched off.
  • the anti-corrosion layer is preferably a white bronze, intermediate between the gold and black. Therefore, the anti-corrosion layer is preferably a plating layer including copper, tin, and zinc to be a white bronze in appearance. This configuration can make the gold of the body of the element less noticeable.
  • the anti-corrosion layer 50 As shown in (c) of FIG. 4 , by applying the anti-corrosion layer 50 to the roughened outer surface 23 of the element 20 , the entire roughened outer surface 23 , i.e., the plurality of recesses 25 and the protrusion 27 , is covered by the anti-corrosion layer 50 .
  • the anti-corrosion layer 50 is formed inside the recesses 25 , which are located deep from the outside, wear of the anti-corrosion layer 50 inside the recesses 25 is suppressed even when the slider passes through. Therefore, even if the anti-corrosion layer 50 on the protrusion 27 is peeled off due to wear, the anti-corrosion layer 50 inside the recess 25 will not peel off.
  • a second, optional coloring backing layer of finishing may be applied which may contribute to the desired final color.
  • a black plating layer coloring backing layer
  • the coloring backing layer is black, the appearance of the element can be maintained in black even if the black paint layer described later peels off.
  • Other options are well known to those skilled in the art.
  • the shades of this backing layer may also contribute to darkening or lightening a top color.
  • the backing layer 60 As shown in (d) of FIG. 4 , by applying the backing layer 60 to the element 20 , the entire anti-corrosion layer 50 on the roughened outer surface 23 (on the recess 25 and the protrusion 27 ) is covered by the backing layer 60 .
  • the backing layer 60 since not only the anti-corrosion layer 50 but also the backing layer 60 is formed inside the recess 25 , which is located deep from the outside, wear of the anti-corrosion layer 50 and backing layer 60 inside the recess 25 is suppressed even when the slider passes through. Therefore, even if the anti-corrosion layer 50 and the backing layer 60 on the protrusion 27 are peeled off due to wear, the anti-corrosion layer 50 and the backing layer 60 inside the recess 25 will not peel off.
  • At least one paint layer preferably a plurality of colored coatings, for example five or more coatings is applied to cover the anti-corrosion layer.
  • the paint layer bears the color.
  • Any appropriate paint or combination of paints such as natural or synthetic resin-based paints may be selected and applied according to the desired color and finish.
  • lacquer, fluoropolymer or ceramic based paints may be selected. Needless to say, if it is desirable to create elements with a black appearance, a black paint layer is applied.

  • the clear coating film 90 protects the anti-corrosion layer 50 , the backing layer 60 , and the paint layer 80 below the clear coating film 90 and suppresses abrasion.
  • the clear coating film 90 is a transparent coating film, and its composition is not limited and known materials can be used.
  • the clear coating film 90 may be made of epoxy, acrylic, urethane, alkyd, or other known resin materials. Since the clear coating film 90 is transparent, the appearance of the element 20 presents the color of the paint layer 80 (e.g., black).
  • the elements may be attached to a tape in a row to form a slide fastener stringer. If the elements are manufactured by an elongate wire member ( FIG. 3 ), this needs to be cut, separating individual elements to be attached to the tape.
  • the step of forming a clear coating film on the element as shown in (f) of FIG. 4 does not necessarily have to be done before the element is attached to the tape, but may be done after the element is attached to the tape.
  • the processes as shown in (a) to (e) of FIG. 4 for roughening and forming the anti-corrosion layer, the coloring backing layer, and the paint layer are all performed before the element is crimped to the fastener tape.

  • a hot-melting coloring material may be thermally transferred from a carrier onto a respective surface portion of the elements, which extends on one side of the tape, thereby leaving a further layer of color on either the upper surface, the lower surface or the upper and lower surface of the attached elements.
  • a layer of lacquer may be applied to the elements, after attaching the elements to the tape, to protect the color and aid the running of the slider.
  • the layer of lacquer is preferably transparent.
  • the elements may be cut from an elongate metal wire member having a transversal cross-sectional shape corresponding to a cross-sectional shape of an element for a slide fastener and being configured to be separated into individual elements to be later attached to a tape.

  • the preliminary roughening process being applied to the wire, when it is subsequently cut, the cut sides do not have roughened surfaces, as the side surfaces will not have existed during the roughening process.
  • the cut sides will form the sides of the elements, that is the parts of the element that face the surface of a neighboring element on the same tape. It will be appreciated that the effects of the roughening treatment will be provided on at least the surfaces of the elements that are more visible once the elements are applied to a tape to form a chain, that including a side that will face the outside of the article to which the elements will be attached.
