Trial Number 1

Trial Purpose:

To further evaluate baking soda blasting for removing oxides and carbon deposits from ceramic part.

Date Run:


Experiment Procedure:

A self-contained blast cabinet was used to deliver the baking soda media to clean the supplied part.  Cleaning took place at a pressure between 40 and 80 psi. Half of the supplied part was subjected to the blast cleaning. The part was cleaned for about 20 minutes. Visual observations were made to determine the effectiveness of the cleaning process.

Trial Results:

The baking soda blasting system was able to remove some of the oxide/carbon deposit from the inner half of the ring, near the edges of the part. The center portion of the part did not appear to be cleaner following media blasting.

Success Rating:

A follow up test, usually based on company input.


Baking soda blasting may be an effective method to remove the contaminants from the ceramic parts. No visual damage was observed on the surface of the part. Under optimized conditions, the process may be further improved. The partially cleaned part will be used in the next evaluation process that will investigate the potential of using laser ablation.
