Erosion Testing of Coatings for V-22 Aircraft Applications

Abstract

High-velocity (183 m/sec) sand erosion tests in a wind tunnel were conducted to evaluate developmental coatings from three separate companies under funding by the Navy's phase I small business innovative research program. The purpose of the coatings was to address a particular problem the V-22 tilt-rotor aircraft (Osprey) was having with regard to ingestion of sand particles by a titanium impeller that was associated with the aircraft's environmental control system. The three coatings that were deposited on titanium substrates and erosion-tested included (1) Si(x)C(y)/DLC multilayers deposited by chemical vapor deposition (CVD); (2) WC/TaC/TiC processed by electrospark deposition; and (3) polymer ceramic mixtures applied by means of an aqueous synthesis. The erosion test results are presented; they provided the basis for assessing the suitability of some of these coatings for the intended application.
