Abstract
A method for manufacturing a component includes a step of providing at least one metallic element. A surface of the at least one metallic element is modified to facilitate a bonding of the at least one metallic element to a polymeric layer. The polymeric layer is then bonded to the at least one metallic element to form the component.
Claims18
A method for manufacturing a component, comprising:
- providing at least one metallic element;
- modifying a surface of the at least one metallic element to facilitate a bonding of the at least one metallic element to a modified polymeric layer;
- bonding the modified polymeric layer to the at least one metallic element
- placing a tie layer about the modified polymeric layer;
- and
- bonding a virgin polymer jacket to the tie layer.
3 more elements
A method for manufacturing a component, comprising:
- providing at least one metallic element;
- heating a surface of the at least one metallic element to modify the surface and facilitate a bonding of the at least one metallic element to a polymeric layer, the heating performed by passing the at least one metallic element adjacent an infrared heat source, the at least one metallic element heated to a temperature of about 500° F. for a time sufficient to modify the surface, the at least one metallic element heated in a modifying fluid that modifies the surface of the at least one metallic element when heated;
- and
- extruding the polymeric layer over the at least one metallic element to bond the polymeric layer to the at least one metallic element;
- placing a tie layer about the polymeric layer;
- and
- bonding a outer polymer jacket to the tie layer.
4 more elements
A component, comprising:
- at least one metallic element having a modified surface;
- and
- a polymeric layer bonded to the at least one metallic element;
- a tie layer bonded with the polymeric layer;
- and
- an outer polymer jacket disposed about the tie layer.
