Methods of coloring titanium alloys and nitinol alloys?

Titanium alloy surface coloring treatment technology

The coloring methods of titanium include atmospheric oxidation, anodization, and chemical treatment. The most commonly used method is anodizing. The following tests can intuitively understand the anodizing method:

1. First mix aqueous solution, sulfuric acid and distilled water

The ratio is less than 1:10, and the concentration of sulfuric acid is low. First, use the waste titanium plate to do the experiment. The titanium plate is the anode, and the thick copper wire is used as the cathode. They are put into the above electrolyte together, and the bubbles start to bubble after the power is turned on.

2. For coloring treatment, put the titanium to be colored into the aqueous solution, the specified voltage is 15V, and the power-on time is not limited. When the aqueous solution slowly turns into a blue copper sulfate solution, it can be seen that the surface of the titanium has been colored.

The coloring methods of nickel-titanium alloys include atmospheric oxidation, anodization, and chemical treatment. The most commonly used method is the anodizing method. The following tests can intuitively understand the anodizing method:
