What are the sandblasting processes for titanium and titanium alloy materials?

1. Dry sandblasting process
Dry sandblasting is the most common sandblasting process. It uses compressed air as power to spray abrasives (such as quartz sand, emery sand, iron sand, etc.) onto the surface of the workpiece to achieve purposes such as cleaning, deburring, and increasing surface roughness.
According to the different parts, select abrasives of different particle sizes and compressed air pressures. For example, larger steel parts with a thickness of more than 3mm May use quartz sand of 2.5-.5mm and compressed air pressure of 0.3-0.5MPa.

2. Wet sandblasting process:
Wet sandblasting is similar to dry sandblasting, but water is added to the abrasive to form mortar, which reduces dust pollution and lowers the surface temperature of the workpiece. Wet sandblasting is often used in situations where high environmental cleanliness is required.

3. Shot peening process:
Shot blasting is similar to sandblasting, but it uses spherical abrasives (such as steel shot or glass shot) instead of sand-like abrasives. Shot peening can generate compressive stress, enhance the fatigue strength and stress corrosion resistance of parts, and is often used for surface treatment of precision parts.

4. Siphon sandblasting:
Siphon sandblasting uses siphons to draw abrasive materials into the airflow and is suitable for surface treatment of small parts with complex shapes.

5. Pressure sandblasting:
Pressure sandblasting uses a pressurized container to rapidly push out grinding materials. It is suitable for large-area surface treatment and has high efficiency, but it also has relatively high requirements for equipment.

6. Wet sandblasting:
Wet sandblasting combines water with grinding materials to reduce dust and clean surfaces, making it suitable for applications where environmental cleanliness is a priority.

7. Spray beads:
Spray beads use glass beads to gently clean and polish surfaces, making them suitable for the treatment of fine surfaces such as jewelry and precision instruments.

8. Dry ice jetting
Dry ice particles are used for cleaning, leaving no residue. It is suitable for applications that require residue-free cleaning, such as food processing equipment. The choice of sandblasting process depends on the type of material to be treated, its surface condition, treatment purpose and environmental requirements. Each sandblasting process has its unique application scenarios and advantages. The correct selection of sandblasting processes can significantly enhance the efficiency and quality of surface treatment.
