Abstract
A cast component includes a body and a passage defined within the body. The passage includes a first portion, a second portion and a turn portion fluidly coupling the first and second portions. The turn portion includes a first surface and a second surface. A surface anti-freckling element extends through the turn portion of the passage from the first surface to the second surface of the turn portion. The element separates the passage in the turn portion into a first sub-passage and a second sub-passage. The element is formed by an opening in a removable core used during the casting that includes a surface anti-freckling opening at the location of the element that provides a path for low-density liquid alloy to flow through a core turn portion of the core to reduce surface freckling of the passage in the body of the component.
