The aim of this investigation is to improve the wear characteristics of black heart malleable cast iron.
The wear resistance under sliding condition of this material containing temper carbon is principally governed by deformation of temper carbon that accompanies plastic flow of the matrix. A hard second phase surrounding temper carbon was introduced by induction hardening as a reinforcement for suppressing deformation of temper carbon. As a result, the amount of sliding wear in the dry condition was efficiently reduced by the second phase surrounding temper carbon and the wear resistance of the irons treated in this manner was markedly improved. It was either the same as or much better than the wear resistance of the high strength malleable cast iron such as JIS-FCMP 55.
