The Cold Jet Process — An Environmentally Sound Alternative for Particles Removal From Advanced Substrates
A process is described for cleaning surfaces by blasting with solid pellets of carbon dioxide. The cleaning mechanism is explained in terms of thermal shock and the effectiveness of contamination removal is assessed by a technique involving the measurement of optically stimulated electron emissions. Case studies illustrating the successful removal of particulates from various substrates are presented.
