+# In cobalt-based and iron-based hardfacing alloys, mixed carbides present in the  microstructure are composed of a metal radical and carbon for example M7C3, M23C6, M3C2  and MC In hardfacings with a fine microstructure the carbides may be too small to have their  corrosion behaviour determined as they are formed in small quantities surrounded by the  matrix phase.
