D'Urso, Brian R.; Simpson, John T.

A method of making a composite material having sharp surface features includes the steps of: making a composite body comprised of a recessive phase and a protrusive phase, the recessive phase having a higher susceptibility to a preselected etchant than the protrusive phase; and treating a surface of the composite body with the preselected etchant so that the protrusive phase protrudes from the surface to form a sharp surface feature, and the recessive phase defines a recessed surface area between the surface features.
