Abstract
An assembly of parts is prepared by providing a female part having a recess and a male part having an inserted surface received within the recess. A relief pattern such as knurling is formed on the inserted surface. The inserted surface of the male part is inserted into the recess of the female part with a contacting-channeled fit between the inserted surface and the recess surface, so that the knurl serves to align the inserted surface within the recess. The inserted surface of the male part is brazed or otherwise joined to the recess of the female part.
Claims20
An assembly of parts, comprising:
- a female part having a recess therein, the recess having a recess surface;
- a male part having an inserted surface received within the recess of the female part;
- a relief pattern on the inserted surface, wherein the recess surface, the inserted surface, and the relief pattern are dimensioned such that the inserted surface is received within the recess with a contacting-channeled fit between the inserted surface and the recess surface, wherein the relief pattern has a relief dimension of from about 0.001 inch to about 0.010 inch and wherein the relief pattern forms channels extending from an external surface of the male part to the inserted surface;
- and
- a joining material that joins the inserted surface to the recess surface, the joining material being disposed within a relief volume of the relief pattern.
An assembly of parts, comprising:
- a female part having a recess therein, the recess having a cylindrical recess surface;
- a male part having a cylindrical inserted surface received within the recess of the female part;
- a relief pattern on the inserted surface, wherein the cylindrical recess surface, the cylindrical inserted surface, and the relief pattern are dimensioned such that the cylindrical inserted surface is received within the recess with a contacting-channeled fit between the cylindrical inserted surface and the cylindrical recess surface, wherein the relief pattern has a relief dimension of from about 0.001 inch to about 0.010 inch;
- and
- a quantity of braze metal disposed between the cylindrical inserted surface and the recess, and disposed within a relief volume of the relief pattern.
A method for preparing an assembly of parts, comprising the steps of:
- providing a female part having a recess therein, the recess having a recess surface;
- providing a male part having an inserted surface receivable within the recess of the female part;
- forming a relief pattern on the inserted surface, wherein the recess surface, the inserted surface, and the relief pattern are dimensioned such that the inserted surface is received within the recess with a contacting-channeled fit between the inserted surface and the recess surface, wherein the relief pattern has a relief dimension of from about 0.001 inch to about 0.010 inch;
- inserting the inserted surface of the male part into the recess of the female part;
- and
- joining the inserted surface of the male part to the recess surface of the female part with a joining material disposed within a relief volume of the relief pattern.
