Abstract
A titanium aluminide (TiAl) coating capable of improving high-temperature oxidation resistance of titanium alloys and a preparation method thereof are provided. The TiAl coating includes α-AlFnanoparticles, and a content of the α-AlFnanoparticles is 5-30 vol. % of the TiAl coating. The preparation method of the TiAl coating includes: using a TiAl alloy target and an α-AlFtarget as raw materials, and performing magnetron sputtering on a substrate surface to prepare a coating; the magnetron sputtering is double-target co-sputtering, and a substrate temperature during the magnetron sputtering is 150° C., the TiAl alloy target is performed direct current sputtering with a power of 0.5-2 kW, and the α-AlFtarget is performed radio frequency sputtering with a power of 0.07-0.2 kW. After the coating is obtained by the double-target co-sputtering, the obtained coating is heat-treated at 600-800° C. for 5-20 h to obtain a final coating.
