Pellet blast cleaning

The removal of T from thick co-deposits (tens of pm) may require the removal of the co-deposits themselves by chemical and/or plasma-assisted oxidizing reactions in the presence of oxygen, or alternatively, via abra-sive/mechanical techniques, such as pellet blast cleaning. From the extensive laboratory measurements of H/D/T removal rates from co-deposited films during exposure to air or oxygen, three key conclusions can be drawn (i) D release occurs in conjunction with C erosion (ii) D-removal and C-erosion rates depend strongly on film structure and (iii) the D release rate during oxidation is a critical function of the specimen temperature.

The report produced by NEWMOA and U.S. EPA also notes that CO2 snow-blasting units are much cheaper to purchase and operate than pellet-blasting units. On average, manual snowblasting units cost about 2000. Semiautomated units are more expensive, ranging from 3000 to 5000 however, these units can be used in assembly applications. CO2 purifiers are also available that can increase the quality of cleaning. These units cost about 5000 (D21488K, p. 27).
