Multilayered Corrosion and Anti-galling Coating for Threads and Wearable Materials

Abstract

A multilayered corrosion and anti-galling coating for threads and wearable materials is a liner that can be superimposed onto the surface of a device in order to protect the surface from environmental hazards. To accomplish this, the coating has a base adhesive layer, an intermediary insulation layer, an interstitial adhesive layer, and a lubricating material layer. The base adhesive layer adheres to the device's surface thus enabling the coating to form a sealing liner. The intermediary insulation layer is positioned in between the base adhesive layer and the interstitial adhesive layer. As a result, the intermediary insulation layer prevents negative chemical interactions between the base adhesive layer and the interstitial adhesive layer. The lubricating material layer is super imposed onto the interstitial adhesive layer to provide a friction-reducing coating for the device's surface.

DETAIL DESCRIPTIONS OF THE INVENTION

[0006] All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

[0007] In reference to FIG. 1 and FIG. 2, the present invention, a multilayered corrosion and anti-galling coating for threads and wearable materials, is a material that can be applied to the surface of a device in order to reduce damage from the environment, friction, and friction-related wear. To achieve this, the present invention makes use of multiple layers of materials that are sequentially deposited onto the device's surface. Specifically, the present invention comprises a base adhesive layer 1, an at least one intermediary insulation layer 2, an at least one interstitial adhesive layer 3, and an at least one lubricating material layer 4. Each of these layers work in concert to provide a coating that reduces damage to the surface of the device, which is caused by environment factors. Preferably the present invention is applied to the surface of interlocking threaded connectors. Thus applied, the present invention prevents damage to the threaded connectors while the connectors are engaged or disengaged. The base adhesive layer 1 is a material that is designed to adhere to the surface of the device. As such, the base adhesive layer 1 is superimposed onto the surface of the device. Preferably the base adhesive later is composed of chrome. Alternatively, the base adhesive layer 1 can be composed of titanium, a chrome-titanium mixture, or various other adhesive materials capable of bonding the present invention to the surface of the device.

[0008] In reference to FIG. 1 and FIG. 2, the arrangement of the layers enables the present invention to make use of materials that would otherwise have negative interactions. Specifically, the present invention makes use of the intermediary insulation layer 2 to isolate the materials of layers which have undesirable interactions. As such, the intermediary insulation layer 2 is superimposed onto the base adhesive layer 1. Additionally, the interstitial adhesive layer 3 is superimposed onto the intermediary insulation layer 2, opposite to the base adhesive layer 1. As a result, the intermediary insulation layer 2 prevents any chemical interaction between the base adhesive layer 1 and the interstitial adhesive layer 3. Preferably the intermediary insulation layer 2 is composed of hafnium oxide. However, the present invention can use various insulating materials to produce the intermediary insulation layer 2.

[0009] In reference to FIG. 1 and FIG. 2, the uppermost layer of the present invention is designed to act as a lubricant. Specifically, the lubricating material layer 4 is superimposed onto the interstitial adhesive layer 3, opposite to the intermediary insulation layer 2. Accordingly, the present invention acts as a liner which prevents the surface of the device form making direct contact with the external environment. Thus, enabling the lubricating material layer 4 to reduce the friction coefficient of the surface of the device. Preferably the lubricating material layer 4 is composed of gold. The present invention makes use of this multilayered structure to form a sealant that protects the surface of the device from corrosion and various other forms of damage caused by hazards in the external environment. Additionally, the present invention is designed with layers of sufficient thickness to protect the surface of the device in an efficient manner.

[0010] In reference to FIG. 1 and FIG. 2, preferably, a thickness 11 of the base adhesive layer 1 and a thickness 31 of the interstitial adhesive layer 3 is less than a thickness 21 of the intermediary insulation layer 2. Further, a thickness 41 of the lubricating material layer 4 is less than the thickness 31 of the interstitial adhesive layer 3. Preferably, the base adhesive layer 1 is 1200 to 1800 angstroms thick, the intermediary insulation layer 2 is 12,000 to 15,000 angstroms thick, the interstitial adhesive layer 3 is 1,200 to 1,800 angstroms thick, and the lubricating material layer 4 is 350 to 400 angstroms thick. An alternative embodiment of the present invention may use additional layers that are stacked onto or interspersed in between the above-described layers. These embodiments comprise layers of material that add desirable surface-protecting features to the present invention.

[0011] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
