Fig 1. Changes in oxygen after long-term storage
Fig 2. Change in specific surface area after long-term storage
After long-term storage of the powder before and after the anti-rust coating, oxygen (Fig. 1) and specific surface area (Fig. 2) were measured.
Since the measured values of oxygen and specific surface area of the powder after anti-rust processing have hardly increased from the time of manufacture,
It has been shown to have anti-rust effect.
