Abstract
A turbine engine component is provided that has a surface that contains a plurality of depressions that are effective to increase the surface area of the component. The depressions are generally concave in contour and improve the heat transfer characteristics of the component. Methods for forming the turbine engine components are also disclosed.
Claims15
A method for forming a turbine engine component, the method comprising the steps of:
- providing a substrate;
- applying a layer on the substrate, said layer comprising a matrix phase and a discrete particulate phase;
- and
- removing selectively and completely at least the discrete particulate phase, leaving behind a plurality of depressions in the matrix phase.

A method for forming a turbine engine component, the method comprising the steps of:
- providing a substrate comprised of a nickel-based or cobalt-based superalloy;
- applying a layer on the substrate, said layer comprising a matrix phase and a discrete particulate phase comprising particles having an aspect ratio of not greater than 1.5;
- heating the substrate to fuse the discrete particulate phase to the substrate;
- and
- removing selectively and completely at least the discrete particulate phase, leaving behind a plurality of depressions in the matrix phase.
