Embodiment 1
[0018] First, take 2 / 3 of deionized water in a 10L tank, dissolve 200g of cetyltrimethylammonium bromide and 4000g of triethanolamine in turn, and after all the reagents in the tank are dissolved, 3000g of titanium fluoroborate and 4000g of hydroxide Pour the sodium into the bath solution under rapid stirring until it is completely mixed, and finally add water to 10L to obtain an oxidation electrolyte, and put the titanium alloy Ti-6Al-4V into the prepared oxidation electrolyte for the first micro-arc plasma deal with. The first micro-arc plasma treatment used Ti-6Al-4V as the anode and graphite as the cathode. The pulse width of the pulse voltage of the first micro-arc plasma treatment and the second micro-arc plasma treatment is 10ns, and the pulse voltage amplitude is 800V. After applying the pulse voltage for 3 seconds, the Ti-6Al-4V was taken out for the second micro-arc plasma treatment. In the second micro-arc plasma treatment, Ti-6Al-4V was used as the cathode and gr...
Embodiment 2
[0020] First, take 2 / 3 of deionized water in a 10L tank, dissolve 300g of tetramethylammonium hydroxide, 2000g of triethanolamine in sequence, and after all the reagents in the tank are dissolved, put 2000g of nickel fluoroborate and 1500g of potassium hydroxide in a fast Pour it into the bath solution under stirring until it is completely mixed, and finally add water to 10L to obtain an oxidation electrolyte. The titanium alloy Ti-2Al-2.5Zr was put into the prepared oxidation electrolyte for the first micro-arc plasma treatment. The first micro-arc plasma treatment used Ti-2Al-2.5Zr alloy as the anode and graphite as the cathode. The pulse width of the pulse voltage of the first micro-arc plasma treatment and the second micro-arc plasma treatment is 100 ns, and the pulse voltage amplitude is 1000V. After applying the pulse voltage for 3 seconds, the Ti-2Al-2.5Zr was taken out and subjected to the second micro-arc plasma treatment. In the second micro-arc plasma treatment, T...
Embodiment 3
[0022] First, take 2 / 3 of deionized water in a 10L tank, dissolve 150g of cetyltrimethylammonium bromide and 3000g of glycerol in turn, and after all the reagents in the tank are dissolved, mix 2500g of nickel fluoroborate and 1200g of hydrogen Sodium oxide was poured into the bath solution under rapid stirring until it was completely mixed, and finally water was added to 10L to obtain an oxidation electrolyte, and Ti3Al was put into the prepared solution for the first micro-arc plasma treatment. The first micro-arc plasma treatment uses Ti3Al as the anode, graphite as the cathode, the nanosecond pulse width is 50 ns, and the pulse voltage amplitude is 1500V, that is, Ti3Al is placed in the solution, and the nanosecond pulse voltage is applied forward for 5 seconds Then take it out and carry out the second micro-arc plasma treatment. The second micro-arc plasma treatment uses Ti3Al as the cathode, graphite as the anode, and applies a pulse voltage for 8 minutes. The thickness ...
