Erosion Testing of Coatings for V-22 Aircraft Applications

Abstract

High velocity (600'/s) sand erosion tests in a wind tunnel were conducted to evaluate developmental coatings from 3 separate companies under Navy phase I SBIR program funding. The purpose of the coatings was to address a particular problem the V-22 (Osprey) tilt-rotor aircraft was having with regards to ingestion of sand particles by a titanium impeller that was associated with the aircraft environmental control system. The three coatings that were deposited on titanium substrates and erosion tested included: (1) Si C/DLC multilayers deposited by CVD, (2) WC/TaC/TiC processed by electro-spark deposition, and (3) polymer ceramic mixtures via an aqueous synthesis. The erosion test results are presented, which provided the basis for assessing the suitability of some of these coatings for the intended application is for the intended application.
