A novel TiAl3/Al2O3 composite coating was prepared on gamma-TiAl alloy. The process included two steps: (1) TiAl3/Al2O3 composite powders were prepared by high energy ball milling of pure Al and nano-TiO2 powders, followed by a heat-treatment; (2) the as-prepared composite powders were deposited on gamma-TiAl substrate by cold spray. The cyclic oxidation was conducted at 900 degrees C to test the performance of the composite coating. The results showed that the composite coating had good crack resistance and effectively decreased the oxidation rate of the substrate. (C) 2015 Elsevier B.V. All rights reserved.
