Test Procedures
During testing, you accelerate solid particles using a compressed gas stream and direct them toward the specimen surface through a calibrated nozzle. The particles impact the specimen at a defined velocity and angle, producing controlled erosion wear.
You regulate erosion conditions by adjusting gas pressure, particle flow rate, nozzle distance, specimen tilt angle, and optional gas temperature. After testing, erosion wear is evaluated by mass loss measurement or surface morphology analysis to determine erosion rate and material performance.
Maintenance Information
(1) Regularly inspect the nozzle for wear or blockage and replace if necessary.
(2) Keep the particle feeding system clean to ensure stable mass flow.
(3) Verify compressed air quality to prevent moisture or contamination.
(4) Check seals, hoses, and fittings for leaks before operation.
(5) Inspect safety enclosure integrity to prevent particle escape.
(6) Calibrate particle flow and pressure settings periodically according to test standards.
