Background
Titanium and titanium alloys are widely used in aerospace, biomedical and automotive applications due to their light weight, high specific strength, good corrosion resistance, good biocompatibility and stable structure, however, titanium alloys have the major disadvantages of low hardness, large friction coefficient, poor wear resistance, and low F-、Cl-And the like, have poor corrosion resistance in environments with strongly aggressive anions, and are susceptible to severe oxidation at 400 ℃. Therefore, in order to improve the high-temperature oxidation resistance of the titanium alloy, the preparation of the coating on the surface of the titanium alloy is one of better solutions.
TiC has high hardness, high elastic modulus, high melting point (3067 ℃), good thermal stability, low friction coefficient, excellent wear resistance and density similar to that of titanium, and is better compatible with titanium alloy in terms of hot physical properties. Therefore, the titanium alloy can be used as a coating material of the titanium alloy to improve the performance of the titanium alloy.
At present, the method for preparing TiC coating on the surface of titanium alloy mainly comprises a laser cladding method, a chemical vapor deposition method, a traditional carburizing method, a surfacing method and the like. The laser cladding method has the defects that in the laser cladding process, molten pool vortex is easily formed under the impact action of laser beams, so that the microstructure of a coating is segregated, cracks are easily formed after the laser beams are quickly solidified due to high temperature, a thin coating can only be prepared by a chemical vapor deposition method and is easily peeled off, the matrix performance is easily damaged due to the overhigh carburizing temperature of the traditional carburizing method, and holes are easily formed in a surfacing method. The molten salt reaction method takes molten salt as a heat transfer medium, and can obviously reduce the reaction temperature and shorten the reaction time by utilizing the characteristics of high ion migration and diffusion speed, uniform mixing of reactants and the like in a molten salt system.
