Embodiment 1
[0016] The processing method for improving the thermal corrosion resistance of diamond abrasives proposed by the present invention includes the following steps:
[0017] S1. Clean and dry the diamond, then soak it in TiO 2 In the sol, take it out after standing, and then dry to obtain material A;
[0018] S2. Place material A in phenolic sol, take it out after standing still, and then dry to obtain material B;
[0019] S3. Put material B in silica sol, let it stand for 2 minutes, take it out, then dry at 102°C for 4 minutes, then heat up to 620°C at 3°C / min, keep it for 4 hours, and then cool down to 180°C at 2°C / min , Keep for 20min, then air-cool to room temperature.
Embodiment 2
[0021] The processing method for improving the thermal corrosion resistance of diamond abrasives proposed by the present invention includes the following steps:
[0022] S1. Clean and dry the diamond, then soak it in TiO 2 In the sol, let it stand for 2 minutes and then take it out, and then dry it at 90°C for 3.5 minutes to obtain material A;
[0023] S2. Place the material A in the phenolic sol, let it stand for 2 minutes, take it out, and then dry it at 65°C to obtain the material B;
[0024] S3. Put the material B in the silica sol, let it stand for 3min, take it out, then dry it at 110℃ for 3min, then increase the temperature to 650℃ at 4℃ / min, keep it for 3h, then decrease the temperature to 160℃ at 3℃ / min , Keep for 30min, then air-cool to room temperature.
Embodiment 3
[0026] The processing method for improving the thermal corrosion resistance of diamond abrasives proposed by the present invention includes the following steps:
[0027] S1. Clean and dry the diamond, then soak it in TiO 2 In the sol, let it stand for 2.5 min and take it out, and then dry it at 95°C for 3 min to obtain material A;
[0028] S2. Place the material A in the phenolic sol, let it stand for 2.5 minutes, take it out, and then dry it at 60°C to obtain the material B;
[0029] S3. Put the material B in the silica sol, let it stand for 2.5min, take it out, then dry it at 106℃ for 3.5min, then raise the temperature to 640℃ at 3.5℃ / min, keep it for 3.5h, then cool it down at 2.2℃ / min To 170℃, keep for 25min, then air-cool to room temperature.
