Atomization plays a crucial role in spray coating processes. The liquid paint is broken up to small droplets and accelerated to the work piece. A conflict of goals is appearing here: A high quality of the layer requires usually a fine atomization, but small droplets can lead to enhanced overspray. Discussions regarding the use of other atomization gases than air shall be focused to a systematic base in this article.
