ABSTRACT
Dry ice blasting is a compressed air process, which uses solid carbon dioxide CO2 at a temperature of -78.5 °C as a one-way blast medium. The main advantages of dry ice
blasting are the sublimation of the blast medium - there are no residues left to be disposed - and the possibility to machine even sensitive surfaces due to the low
abrasiveness of the process. Commonly dry ice blasting is used for cleaning operations or for paint removal.
Recent investigations have shown that despite the low abrasiveness of the process it is possible to use dry ice blasting for shot peening applications. Depending on the
material to be machined it is possible to roughen the surface and to insert residual stresses. Both effects may be used for preparation of adherence processes without the
disadvantages of other blasting media e. g. doting surfaces with the media.
