An Analysis of Induction Hardening of Ferritic Ductile Iron
Achievements of the induction hardening of ferritic iron were investigated. Ductile iron is not advisiable for the use in induction hardening because of the smallcarbon content in the metal matrix of ferritic ductile iron. The carbon content in the metal matrix of ductile iron can be increased by additional preparation of metal matrix before final inducton heat hardening. Wear resistance of the induction hardened ferritic ductile iron can increase as result of increased carbon content of the metal matrix and higher hardness after induction hardening. Some heat pretreatments for metal matrix preparation were applied before the induction hardening of ferritic ductile iron. The process parameters of the induction hardening heat pretreatment were analyzed and optimized. According to recommended elemental composition of ferritic ductile iron and required mechanical properties, the process parameters of the investigated induction heat pretreatment were optimized.The efficiency of pretreatment processes of induction hardening was analyzed. Applicability and manufacture ability of engineering components by proposed heat preteratment were investigated. The limitations of the investigated heat pretreatment applications were estimated by the comparison of mechanical properties of heta-treated specimens.
