Improved wear resistance of P/M tool steel alloy with different vanadium contents after ion nitriding
R.M. Muñoz Riofano,Luiz Carlos Casteletti,Lauralice de Campos Franceschini Canale,George E. Totten +3 more
TL;DR: In this paper, the influence of vanadium on the ion nitriding process and the abrasive wear of ion-nitrided P/M materials was studied and it was verified that the hardness increase resulted in a smaller mass loss when the compound layer composition is primarily VN and γ I -Fe 4 N.
