1：Experimental Design and Method Selection:

The study used micro arc oxidation (MAO) to deposit TiO2 ceramic coatings on pure titanium substrates. Different electrolytes were prepared: base sodium silicate solution, base with GO addition, and base with GO and SDBS addition. The MAO process was conducted under constant voltage mode with predefined parameters.

2：Sample Selection and Data Sources:

Pure titanium samples (Ф16 mm×5 mm) were mechanically polished and ultrasonically cleaned. Coatings were prepared and analyzed using various characterization techniques.

3：List of Experimental Equipment and Materials:

Equipment included a MAO deposition system, SEM, EDS, XRD, scratch tester, nano-indentation system, electrochemical system, and UV spectrophotometer. Materials included pure titanium, sodium silicate, graphene oxide (GO), sodium dodecyl benzene sulfonate (SDBS), and methylene blue (MB) solution.

4：Experimental Procedures and Operational Workflow:

Samples were prepared by MAO in different electrolytes. Coatings were characterized for morphology (SEM, EDS), phase composition (XRD), binding force (scratch tester), mechanical properties (nano-indentation), corrosion resistance (electrochemical tests in NaCl solution), and photocatalytic activity (degradation of MB under UV light).

5：Data Analysis Methods:

Data were analyzed using software like Jade5.0 for XRD phase quantification, and results were compared statistically (e.g., average values from multiple indentations).
