Abstract
A surface area of a structure is fabricated with a textured surface that reduces the surface wear rate or erosion caused by a high speed flow of fluid containing abrasive particles over the surface area. More particularly, a leading edge surface such as a rotor leading edge surface, an aircraft airfoil leading edge surface, a propeller leading edge surface, etc. is fabricated with a textured surface comprised of a plurality of grooves that alter or break up a high speed flow of fluid containing abrasive particles over the textured surface. The grooves are contacted by the high speed flow of fluid containing the abrasive particles and alter or break up the flow of fluid and abrasive particles and thereby reduce surface wear rate or erosion of the structure leading edge.
