Abstract
Studying steel wear is extremely important to industry as the use of current tribology knowledge and technologies could generate significant savings worldwide. This work aims to evaluate the relationship between hardness, wear and microstructure of a tribological pair formed by SAE 1045 steel - quenched and normalized - and zirconium oxide, a high hardness material. For this purpose, the pair of materials was subjected to pin-on-disc wear tests. By means of microscopy and interferometry, the wear mechanisms were evaluated. Abrasion and adhesion mechanisms were observed at the end of the tests for all quenched and normalized samples. It was observed that the normalized discs presented lower hardness and higher wear, while the respective balls presented elliptical marks due to the lower hardness of the material.
