Embodiment 1
[0038] The present invention comprises the following steps:
[0039] The first step: diamond surface pretreatment
[0040] First, the diamond abrasive grains with a particle size of 10 μm were boiled in a 10% NaOH solution for 20 min, and washed with water until neutral; then, the cleaned diamond abrasive grains were placed in a 10% HNO 3 Boil in the solution for 20 minutes, and wash with water until neutral;
[0041] The second step: diamond surface sensitization and activation
[0042] First, the pretreated diamond abrasive grains were placed in a sensitizing solution, sensitized at room temperature for 10 min, and washed to neutrality; then, the cleaned diamond abrasive grains were placed in an activation solution, and activated at room temperature for 10 min , and washed to neutrality; the composition of the sensitization solution is: SnCl 2 2H 2 O: 10g / L, HCl: 30ml / L; the composition of the activation solution is: PbCl 2 : 0.5g / L, HCl: 10ml / L;
