Common surface treatments include sandblasting, galvanizing, phosphating, and passivation, to improve corrosion resistance, aesthetics, and processing performance.

Precautions:

1. Before surface treatment, thorough preparation must be carried out according to product requirements to ensure the quality of the workpiece surface.

2. During the surface treatment process, the prescribed sequence of steps must be followed to avoid quality problems.

3. Tools must be used skillfully for fast and accurate processing.

4. After surface treatment, a strict inspection must be conducted to ensure that the specified standards are met.

5. Any conditions that may damage the surface treatment must be carefully controlled.

6. The operating procedures must be strictly followed to ensure quality control requirements are met and to provide complete protection for the product surface.

7. Attention must be paid to odors during the surface treatment process.
