Rajiv Kohli    The Aerospace Corporation, Houston, Texas, USA

Abstract

The use of water ice (or ice blasting) has been developed as a nonsolvent, dry method for removing surface contaminants in a variety of cleaning applications. The basic principle is based on the impact of ice particles on the surface of the part. Contaminants on the surface are displaced by impact energy and the melting ice flushes away the debris. A discussion of the process is provided along with description of the cleaning systems employing ice blasting. The advantages and disadvantages of ice blasting are discussed, along with cost considerations. Several applications of ice blasting in different industries ...
