[0027] Example 1
[0028] The preparation method of TiSiN nanocomposite coating on the surface of titanium alloy mainly includes the following steps:
[0029] The first step is to put the titanium alloy sample into the sealed box of the laser surface treatment device;
[0030] In the second step, the sealing box is evacuated through the air outlet connected with the vacuum generating device on the sealing box, and nitrogen is introduced into the protective gas channel connected with the sealing box through the air inlet connected with the nitrogen source on the sealing box, so that A pure nitrogen atmosphere is maintained in the protective gas channel and the sealed box, and the speed of the nitrogen introduction is 100L / min;
[0031] The third step is to turn on the laser connected to the protective gas channel. The laser beam emitted by the laser enters the sealed box through the protective gas channel and sweeps across the surface of the titanium alloy sample at a constant...
