Abstract
Bulk metallic glass (BMG) is supposed to have a good erosion–corrosion (E–C) resistance due to its high hardness and good corrosion resistance. To reveal the E–C behavior, Zr55Cu30Ni10Al5·BMG is investigated using a slurry pot erosion tester. Experimental results show the volume loss rate of BMG increases with an increase in the particle size, sand concentration or impact velocity. The corrosion current density and the synergism rate increase with the increasing impact velocity. During E–C process, the surface microstructure transforms gradually from pure amorphous to composite mixture of crystalline and amorphous phases. The E–C resistance of BMG is better than that of 304 stainless steel, but not as expected as its high hardness.
