Microstructure and Properties of Ti–Al Coating on Titanium Alloy Surface Assisted by Electromagnetic Field

The effect of an alternating electromagnetic field on the microstructure and properties of the Ti-Al coating on the titanium alloy surface is studied. The Ti-Al coating is prepared on the surface of titanium alloy by using an alternative electromagnetic field assisted by high temperature thermal diffusion. The preparation method is simple and easy to operate. The microstructure and element distribution of the coating under different magnetic field intensities are analyzed. The mechanism of improving the comprehensive properties of coatings by alternative electromagnetic fields with different intensities is discussed. The test results show that the outer surface of TA
