Abstract
The paper presented here belongs to the researches about the influence of the technological parameters for obtaining a special wear-resistant spheroidal graphite cast iron and his abrasive wear. The studied cast iron had an addition of copper and molybdenum and was elaborated in an induction furnace and the nodular changes were obtained with the “In mold” method. Start from a perlito-feritic structure in the raw state, after applying an isothermal heat treatment, the structure is constituted of inferior binate, residual austenite and marten site with optimal values of abrasive wear and micro-hardness. This material is used for a few automotive components with good results and the abrasive wearing was done on a laboratory plant type.
