Will The Titanium Products Processed By The Technology Lose Their Paint?

Anodizing and painting are completely different technical approaches, which determines that it has no possibility of the traditional "peeling off" phenomenon:

 Anodizing is a "growing" film layer on the surface, rather than an adhered coating.

Anodizing is achieved through electrochemical treatment, allowing the atoms on the surface of the titanium alloy to directly transform into a layer of titanium dioxide (TiO₂) film. This layer is atomically bonded to the base metal and has no obvious interface, equivalent to a part that "grows" out from the material itself. While painting is like "putting a coat" on the material, the paint is physically covered on the surface and only relies on adhesion to combine with the base material. Over time or with more impacts, it is prone to complete detachment, peeling, and bulging.

 The color comes from physical effects, no pigment layer.

The color of the titanium alloy anodized coating is due to the interference effect of the film layer. Different thicknesses of the oxide film will result in different interference effects on light, which will present abundant colors. The entire process does not add any pigments, and there is naturally no problem of pigment layer peeling off.

Although there won't be paint-like peeling off, under extreme conditions, the titanium alloy anodized film may suffer from wear and corrosion, resulting in an appearance change similar to "color fading", mainly divided into two situations:

 Mechanical wear (most common)

The thickness of the titanium alloy anodized film is usually only several tens to several hundred nanometers, although its hardness is higher than ordinary paint, it is still lower than the titanium alloy substrate. Under long-term friction, hard objects scraping, and repeated impacts, the film layer will gradually be damaged:

Mild wear: The film layer becomes thinner, the color becomes lighter and darker, for example, dark blue may turn into light blue, gold may fade to pale yellow;

Severe wear: The film layer is completely worn through, revealing the silver gray of the titanium alloy itself, looking like "a piece of color has fallen off". However, normal hand-touching, light wiping and other normal usage scenarios will not cause the film layer to be worn.

 Chemical corrosion

Long-term exposure to strong acids, strong alkalis, and high-concentration chloride ions (such as seawater, 84 disinfectant, etc.) will slowly corrode the anodized film, causing spots, darkening, and local color loss problems, which also look similar to "color fading" from an appearance perspective, but this is the manifestation of the film layer being corroded, and it is fundamentally different from paint peeling off.
