# 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.
# Explain the role of the hard carbide network as the primary defense against abrasive wear.
# Classify the principal carbide types based on their forming elements and stoichiometry:
# Chromium Carbides: Discuss the formation and properties of M7C3 and M23C6 carbides.
