Comportamiento frente al desgaste por abrasión de cuatro tipos de fundiciones

Abstract

This work studies the abrasion wear behavior of four cast irons: white iron, ferritic ductile iron, ductile iron with boron and Nihard. Chemical composition and metallographic structure were determined in all of them. The abrasion wear behavior study was carried out by pin on disk test setting load, speed and pìn material and calculating the weight loss. Also the variation of the friction coefficient and surface hardness was calculated in all the cases
