Embodiment 1
[0082] First, put the titanium alloy in an acetone solution and ultrasonically clean it for 5 minutes to 10 minutes. After cleaning, rinse with distilled water for later use.
[0083] Then, put the titanium alloy obtained in the previous step into a degreasing solution at 60° C. for 20 minutes, so as to remove the oil stain on the surface of the titanium alloy. Wherein, the degreasing liquid can be prepared in advance, and its preparation method is to add 60 g of sodium silicate, 60 g of sodium carbonate, and 150 g of sodium hydroxide into 3 L of deionized water, stir and dissolve evenly.
[0084] After degreasing, wash with flowing hot water first, and then wash with flowing cold water.
[0085] Finally, put the titanium alloy obtained in the previous step into the anodic oxidation electrolyte for 60 minutes to carry out anodic oxidation treatment. Wherein the anodic oxidation electrolyte can be prepared in advance, and the preparation method comprises: adding 45g of malic ...
Embodiment 2
[0092] First, configure the degreasing fluid as follows:
[0093] Add 20g of sodium silicate, 20g of sodium carbonate, and 50g of sodium hydroxide into 1L of deionized water, stir and dissolve evenly.
[0094] Prepare the anodizing solution as follows:
[0095] Add 45g of malic acid and 30mL of PTFE emulsion into 3L of deionized water, stir and dissolve evenly. The concentration of malic acid in the anodizing solution is 15g / L.
[0096] Then, start to anodize the titanium alloy according to the following steps.
[0097] Put the titanium alloy in the acetone solution and ultrasonically clean it for 5 minutes to 10 minutes. After cleaning, rinse with distilled water for later use.
[0098] Then, put the titanium alloy obtained in the previous step into the prepared degreasing liquid for processing, the temperature of the degreasing liquid is 60°C, and the processing time is 20 minutes. In order to facilitate the removal of oil stains on the surface of titanium alloys. Afte...
Embodiment 3
[0105] 1. Prepare alkaline degreasing fluid
[0106] Add 20g of sodium silicate, 20g of sodium carbonate, and 50g of sodium hydroxide into 1L of deionized water, stir and dissolve evenly.
[0107] 2. Preparation of anodizing solution
[0108] Add 150g of malic acid and 30mL of PTFE emulsion into 3L of deionized water, stir and dissolve evenly.
[0109] 3. Anodizing treatment
[0110] Put the titanium alloy in acetone solution and ultrasonically clean it for 5-10 minutes, take it out and rinse it with distilled water for later use.
[0111] Alkaline washing and degreasing of the cleaned titanium alloy in the prepared degreasing solution at a temperature of 60°C for 20 minutes, and then washing with flowing hot water and flowing cold water;
[0112] Put the degreasing titanium alloy into the prepared anodic oxidation solution for 60min. Among them, the conditions of anodizing treatment are as follows: current density of pulse power supply is 5A / dm2; pulse frequency is 1.3Hz; d...
