Abstract: A cylinder head valve seat of an automobile vehicle includes a valve seat having a valve seat surface integrally joined to an engagement end. The engagement end includes multiple materials extending through a cross section of the engagement end. The multiple materials include: a first material having a first thermal conductivity; and a second material having a second thermal conductivity higher than the thermal conductivity of the first material, wherein the first material transitions into the second material.

Abstract: A three-dimensional part as well as a method and system for creating the three-dimensional part. The three-dimensional part including a first portion of a three-dimensional part formed from a first plurality of successively deposited layers, with a cavity defined in the first portion of the three-dimensional part. A magnet is inserted in the cavity and a cover disposed on the magnet in the cavity. In addition, a second portion of the three-dimensional part is formed form a second plurality of successively deposited layers deposited on the first portion of the three-dimensional part and the cover.

Abstract: A flow conditioning device includes a body portion having first and second ends and an interior surface defining a channel extending from the first end to the second end, and one or more flow conditioning elements disposed within the channel. Each of the one or more flow conditioning elements is integrally formed with the interior surface of the body portion, and may be a respective flow straightening tube, a flow straightening vane, a hole array plate, a turning vane, a swirling vane, a helical ridge formed along a respective longitudinal segment of the interior surface, or another configuration. The body portion and the one or more flow conditioning elements may be formed by an additive manufacturing process, and may optionally be made of the same material.
