Abstract
Official abstract text for this publication.
A method of providing a threaded fastener with a multi-layered coating comprises the step of using a vapor deposition process to apply a multi-layered coating to a threaded portion of the threaded fastener, each layer of the multi-layered coating being formed from a coating material selected from the group comprising titanium, chromium, nickel, platinum, tantalum, and combinations thereof.
First claim
Opening claim text (preview).
What is claimed is: 1. A threaded fastener comprising a threaded portion, wherein the threaded portion is coated with a multi-layer coating, each layer of the multi-layered coating being formed from a coating material selected from the group consisting of titanium, chromium, nickel, platinum, tantalum, and combinations thereof, and wherein the threaded fastener is adapted to receive a threaded nut. 2. The threaded fastener as claimed in claim 1 , wherein the multi-layered coating comprises between ten and seventy individual coating layers. 3. The threaded fastener as claimed in claim 1 , wherein each layer of the multi-layer coating has a thickness in the range of 10 nm to 100 nm. 4. The threaded fastener as claimed in claim 1 , wherein the multi-layer coating has a thickness in the range of 0.5 μm to 15 μm. 5. The threaded fastener as claimed in claim 1 , wherein the coating material is nickel. 6. The threaded fastener as claimed in claim 1 , wherein each individual coating layer forming a single layer group of the multi-layer coating is formed from the same coating material. 7. The threaded fastener as claimed in claim 1 , wherein individual coating layers forming a single layer group of the multi-layer coating are not all formed from the same coating material. 8. The threaded fastener as claimed in claim 1 , wherein the multi-layer coating is the outermost coating of the threaded fastener.
