Abstract

The many problems associated with erosion-corrosion of metals observed in coal conversion systems have led to a program to study such phenomena. Initially, a gun capable of shooting 0. 343 mm diam tungsten carbide spheres at velocities up to 150 m/s was constructed and mounted on a scanning electron microscope (SEM) to allow in-situ erosion studies. Subsequent modifications to the SEM added a hot stage and capability for in-situ corrosion. Studies to date have included observations of the erosion of gold, copper, and stainless steel by WC spheres. Evidence of local melting and formation of lips has been obtained by scanning electron microscopy.
