To improve aircraft performance in adverse service environments; specific coatings are applied to critical surfaces to improve (i) erosion; (ii); corrosion; (iii); hydrophobic; or (iv) icephobic properties. Although protective coatings are available in all four groups; aerospace applications require combinations of properties that are not readily available; for example hydrophobicity together with erosion resistance. The combination of hydrophobic (or icephobic) and erosion properties is difficult to obtain. Known hydrophobic or icephobic materials are usually polymers that are too soft to provide required erosion resistance and durability in aircraft service conditions. Conversely; physical vapour deposited coatings that are erosion resistant and durable; typically do not have adequate hydrophobicity. However; recent studies on amorphous carbon (a-C) coatings indicate that these materials have potential for combined hydrophobic and erosion applications through doping or compositional changes. Thus; this paper reports on improving the hydrophobic and erosion resistance properties of nonhydrogenated a-C coatings doped with a single element such as chromium (Cr); silicon; (Si); aluminum; (Al); or titanium (Ti) up to 12 at.%. All coatings are produced using unbalanced magnetron sputtering and characterized by scanning electron microscopy; energy dispersive X-ray spectroscopy; X-ray diffraction; nanoindentation; and water contact angle measurements. The most prospective compositions are evaluated for erosion resistance and ice adhesion strength testing. Overall; the best combination of hydrophobic and erosion properties is obtained for a-C doped with 10 at.% of Al; whereas the ice adhesion results against bare steel substrate have been inconclusive. © 2015 Government of Canada;
