Conical pins for the structural repair of defects

A method, comprising:

• creating a void at a location of a defect in a component to remove the defect;
• creating an insert of a shape and a size corresponding to the void;
• inserting the insert into the void;
• creating a first plurality of conical holes along a perimeter of the insert, a spacing between adjacent conical holes being less than a diameter of a conical hole at a surface of the component;
• forcibly positioning a first plurality of conical pins into the first plurality of conical holes;
• forming a bond between each of the first plurality of conical pins and a corresponding one of the first plurality of conical holes in response to forcibly positioning each of the first plurality of conical pins into the corresponding one of the first plurality of conical holes;
• for each of the first plurality of conical pins, stopping the forcible positioning after a coating on the first plurality of conical pins locally plasticizes creating a high tensile strength bond between the pin, the component, and the insert in response to softening and hardening of the coating;
• creating a second plurality of conical holes along the perimeter of the insert, each of the second plurality of conical holes overlapping adjacent conical holes of the first plurality of conical holes;
• forcibly positioning a second plurality of conical pins into the second plurality of conical holes;
• forming a bond between each of the second plurality of conical pins and a corresponding one of the second plurality of conical holes in response to forcibly positioning each of the second plurality of conical pins into the corresponding one of the second plurality of conical holes;
• for each of the second plurality of conical pins, stopping the forcible positioning after a coating on the second plurality of conical pins locally plasticizes creating a high tensile strength bond between the pin, the component, and the insert in response to softening and hardening of the coating;
• and
• removing portions of the first and second plurality of conical pins extending above the surface of the component.

A method, comprising:

• creating a conical hole at a location of a defect in a component;
• driving a conical pin into the conical hole;
• forming a bond between the component and the conical pin in response to heat generated from friction;
• and
• removing a portion of the conical pin extending from the conical hole.
