Atmospheric Oxidation: Nature's Palette
Atmospheric oxidation offers a relatively simple and cost-effective coloring method. Titanium components are heated in air using equipment like electric furnaces. During heating, an oxide film gradually forms on the surface. Through light interference, this film creates mysterious color variations. After natural cooling to stabilize the oxide layer, the coloration appears. While somewhat unpredictable, this randomness ensures unique artistic results.

Advantages: Simple process, low equipment requirements, cost-effective, suitable for mass production
Disadvantages: Uneven coloration, requires multiple trials, strong randomness in color control

Anodic Oxidation: Fusion of Technology and Aesthetics
This precise method uses titanium as the anode and stainless steel as the cathode in an electrolyte. Applying controlled voltages generates uniform oxide films with specific thicknesses. These films exhibit excellent corrosion/wear resistance while displaying interference colors.

Advantages: Stable color control, uniform film thickness, enhanced durability, cost-effective process
Disadvantages: Limited hardness for special applications, thickness variations from electrolyte composition/voltage fluctuations

Electrochemical Coloring: Eco-Friendly Innovation
Specifically for titanium alloys, this electrolytic process uses multi-acid electrolytes to create colored oxide films. The environmentally friendly solution contains no toxic substances but requires specialized equipment.

Advantages: Stable eco-friendly solution, diverse color options, customizable effects
Disadvantages: Higher costs, professional operation required, potential color fading from environmental exposure
