Abstract

Studs, nodes, and study assembly systems formed by various methods are disclosed. Various disclosed methods include cold spraying a powder onto a substrate to form a node on the substrate and drilling a hole only into the node. Various disclosed methods include cold spraying a powder onto a substrate to form a node and machining the node to form a stud.

First claim

What is claimed is:

1. A method comprising:
cold spraying a powder onto an outer surface of a substrate to form a node on the substrate, wherein the node extends above an exposed portion of the outer surface, the exposed portion being adjacent to the node;
drilling a hole only into the node; and
inserting a stud into the node.

2. The method according to claim 1 , further comprising plating the node on the substrate.

3. The method according to claim 1 , wherein the cold spraying the powder comprises cold spraying at least one of silicon carbide, stainless steel, aluminum, titanium, copper, tantalum, nickel, tungsten, and alloys thereof.

4. The method according to claim 1 , wherein the cold spraying the powder comprises at least one of a high pressure cold spraying and a low pressure cold spraying.

5. The method according to claim 1 , wherein the exposed portion of the outer surface is immediately adjacent to the node.

6. A method comprising:
cold spraying a powder onto a substrate to form a node, wherein the node extends above an outer surface of the substrate; and
machining the node to form a stud extending from the substrate; and
forming threads on the stud.

7. The method of claim 6 , wherein the cold spraying the powder comprises cold spraying at least one of silicon carbide, stainless steel, aluminum, titanium, copper, tantalum, nickel, tungsten, and alloys thereof.

8. The method according to claim 6 , further comprising plating the node.

9. The method according to claim 6 , wherein the cold spraying the powder comprises at least one of a high pressure cold spraying and a low pressure cold spraying.

10. A method comprising:
cold spraying a powder onto an outer surface of a substrate to form a node on the substrate, wherein the node extends above an exposed portion of the outer surface, the exposed portion being adjacent to the node;
drilling a hole only into the node; and
tapping the drilled hole.

11. The method according to claim 10 , further comprising threading a threaded stud into the tapped hole.
