Abstract
An automotive engine component and method of producing the same. The method uses dynamic magnetic compaction to form components, such as camshaft lobes, with non-axisymmetric and related irregular shapes. A die is used that has an interior profile that is substantially similar to the non-axisymmetric exterior of the component to be formed such that first and second materials can be placed into the die prior to compaction. The first material is in powder form and can be placed in the die to make up a first portion of the component being formed, while a second material can be placed in the die to make up a second portion of the component. The second material, which may possess different tribological properties from those of the first material, can be arranged in the die so that upon formation, at least a portion of the component's non-axisymmetric exterior profile is shaped by or includes the second material.
