Abstract
A turbulator fabrication process and a fabricated article are provided. The turbulator fabrication process includes providing a system configured for directing a first fusion energy and a second fusion energy, positioning a turbulator material on a substrate, and directing the first fusion energy and the second fusion energy toward the turbulator material and the substrate. The directing of the first fusion energy and the second fusion energy modifies the turbulator material forming one or more turbulators on the substrate. The fabricated article includes a substrate and one or more turbulators formed on the substrate. Each of the one or more turbulators includes at least one root portion providing a concave transition between the substrate and the turbulator.
