The Influence of Heat Treatment on Wear Resistance of High Cr White Cast Iron

Wear resistance of high Cr white cast irons can be improved by means of heat treatment. The purpose of this work was to study the influence of parameters such as quenching and tempering temperatures and sub zero treatment in the abrasion wear performance of the high Cr white cast iron Nb alloyed. Pin-on-disc abrasion tests were performed and the worn surface was examined by SEM. The main wear mechanisms were identified. This Fe alloy has shown good performance for applications in mining and alcohol-sugar industries.
