Abstract
A system for an engine comprises a component manufactured via additive manufacturing. The component includes a first material with a first contraction rate. An insert is disposed in the component and comprises a second material with a second contraction rate that is lower than the first contraction rate. When the component and the insert are exposed to a temperature suitable for sintering, the component contracts around the insert, thereby coupling the insert and the component.
Claims12
A system for an engine, comprising:
- an engine component manufactured via additive manufacturing, the engine component comprising a first material of a first density with a first contraction rate and a ledge;
- and
- an insert disposed in the engine component and in contact with the ledge, the insert comprising a second material of a second density with a second contraction rate that is lower than the first contraction rate, the second density greater than the first density;
- wherein when the engine component and the insert are exposed to a temperature suitable for sintering, the engine component contracts around the insert, thereby coupling the insert and the engine component.

A component in an engine, comprising:
- a body including a ledge and comprising a first material of a first density with a first contraction rate;
- and
- an insert disposed in the body and in contact with the ledge, the insert comprising a second material of a second density with a second contraction rate that is lower than the first contraction rate, the second density greater than the first density, such that when the body and the insert are exposed to a temperature suitable for sintering, the body contracts around the insert to form a bulge having a greater width than a width of the body above and below the insert.
An engine system, comprising:
- a component comprising a first material of a first density with a first contraction rate, the component defining an opening that extends through a central portion of the component;
- and
- an insert disposed in the component, the insert comprising a second material of a second density with a second contraction rate that is lower than the first contraction rate, the second density greater than the first density,
- wherein the component comprises a ledge that extends into the opening, the ledge in contact with the insert.
