Example Embodiment
[0030] Example 1. First, a titanium plate of 10mm×10mm×1mm was alkali washed at 60°C for 30 minutes, etched with 10% oxalic acid at 90°C for 2.5 hours, washed with deionized water ultrasonically for 10 minutes, and dried for use.
[0031] Weigh a certain quality of H 2 IrCl 6 And Ce(NO 3 ) 3 Miscible with tetraethyl silicate, let stand at room temperature for 2 hours.
[0032] Ce(NO 3 ) 3 , H 2 IrCl 6 The mixed solution of tetraethyl silicate and tetraethyl silicate is dissolved in a mixed solvent of n-butanol and isopropanol mixed in a ratio of 1:1 to obtain a coating solution. Ce(NO 3 ) 3 , H 2 IrCl 6 The molar concentrations of tetraethyl silicate and tetraethyl silicate are 0.018, 0.042 and 0.14 mol / L, respectively.
[0033] The prepared coating solution is evenly coated on the pretreated titanium substrate surface with a brush, dried at 120°C for 10 minutes, then sintered at 450°C for 10 minutes, taken out and cooled to room temperature. After the above steps are repeated 25 ti...
