In this paper, a computational method to predict the corrosion resistance of some ironbased powder metallurgy (P/M) materials is proposed. The samples prepared from
atomized iron powder and pre-alloyed iron base powders powders were the materials
analyzed in this paper. The compacted samples were obtained by powder metallurgy
process, respectively pressing and sintering of the mixed powders. The samples were
compacted at a pressures of 400 and 600 MPa. The sintering temperature was
approximately 1.150 °C. The influence of green porosity, the particle sizes, sintering
time and corrosion time on properties of the analyzed samples were investigated. An
increase in the sintered density of the samples was correlated with a lower porosity and
smaller pore size and, as a consequence, a high corrosion resistance. Porosity, particle
size and sintering time were defined as the input variables of the model. Corrosion time
was used as the outputs variables of the model. It is observed that the values obtained by computational method are in good correlation with the experimental values. The
viability of the computational model used is confirmed . The computational method
studied in this paper can be used as an alternative to predict the corrosion resistance of some iron-based materials obtained by powder metallurgy route.
