Abstract

A multi-layer friction reducing tape, including: a foil layer including a metal, polymer, or hybrid-metal-polymer; an under layer disposed on the foil layer; an adhesion promoting layer contiguous with a surface of the under layer; a functional layer that includes a fullerene based composite, a diamond based material, diamond-like-carbon (DLC), or combinations thereof, wherein the functional layer is contiguous with a surface of the adhesion promoting layer; and a tape, including an adhesive layer and a backing material, wherein the adhesive layer is attached to a surface of the foil layer opposite the under layer.

First claim

What is claimed is:

1. A method of manufacturing a multi-layered friction reducing tape, comprising:
obtaining a foil layer including a metal, polymer, or hybrid-metal-polymer;
coating the foil layer with a friction reducing coating; and
applying an adhesive material and removable film to a side of the foil layer opposite the friction reducing coating, wherein the friction reducing coating is a multi-layered friction reducing coating that includes, an under layer disposed on the foil layer, an adhesion promoting layer contiguous with a surface of the under layer, and a functional layer that includes a fullerene based composite, a diamond based material, diamond-like-carbon (DLC), or combinations thereof, wherein the functional layer is contiguous with a surface of the adhesion promoting layer; and
wherein the coating includes only depositing the under layer in a tile pattern on the foil layer using a mask disposed on the foil layer.

2. The method of claim 1 , wherein the obtaining includes obtaining a foil layer that is a strip.

3. The method of claim 1 , wherein the coating is performed in a chamber.

4. The method of claim 1 , wherein the foil layer is a metal foil.

5. The method of claim 1 , wherein the tile pattern is herringbone.

6. The method of claim 1 , wherein the tile pattern is honeycomb.

7. The method of claim 1 , wherein the coating includes depositing an entirety of the multi-layered friction reducing coating in the tile pattern on the foil layer using a mask disposed on the foil layer.

8. The method of claim 1 , wherein the coating includes creating smooth tapering zones in the functional layer to avoid stress concentration areas for the functional layer.

9. The method of claim 7 , wherein the coating includes applying the functional layer on the under layer to provide a surface that is recessed at joints in the tile pattern.

10. The method of claim 2 , wherein a thickness of the tile pattern is larger than a thickness of the foil layer.
