Abstract
A combustor liner includes panels joined together at a cooling nugget including a bridge and a lip extending therefrom. The lip defines a slot terminating in an outlet. Thermal barrier coating covers inboard surfaces of the panels and lip with a nominal thickness. The lip has a distal end at the slot outlet which is spaced from the coating aft of the slot less than about the coating nominal thickness.
