Claims12
A combustor panel of a combustor, comprising:
- a combustion facing surface comprising a metallic coating and a ceramic coating;
- a cooling surface opposite the combustion facing surface;
- and
- heat transfer pins extending from the cooling surface, wherein a grouping of the heat transfer pins comprises the metallic coating without the ceramic coating wherein the grouping of the heat transfer pins is an aft grouping, wherein the aft grouping comprises at least one row of the heat transfer pins adjacent an aft edge of the combustor panel.

A combustor of a gas turbine engine, comprising:
- an outer shell;
- an inner shell;
- an outer combustor panel mounted to, and radially inward of, the outer shell, the outer combustor panel comprising a first combustion facing surface comprising a metallic coating and a ceramic coating;
- and an inner combustor panel mounted to, and radially outward of, the inner shell, the inner combustor panel comprising a second combustion facing surface comprising the metallic coating and the ceramic coating;
- wherein a first plurality of heat transfer pins extend radially outward from a radially outward surface of the outer combustor panel and a second plurality of heat transfer pins extend radially inward from a radially inward surface of the inner combustor panel
- wherein a first grouping of the first plurality of heat transfer pins comprises the metallic coating without the ceramic coating and a second grouping of the second plurality of heat transfer pins also comprises the metallic coating without the ceramic coating;
- wherein the first grouping of the first plurality of heat transfer pins and the second grouping of the second plurality of heat transfer pins comprise respective aft groupings, wherein the respective aft groupings each comprises a row of heat transfer pins adjacent respective aft edges of the outer combustor panel and the inner combustor panel.
