Abstract
FeCrCB alloys have become an attractive option as a hardfacing coating to extend the service life of tools used in primary and secondary industries. In this work, experiments are reported on the sintering of FeCrCB alloy powders for hardfacing coatings by modifying the CO2/CO ratio using six different atmospheric gas conditions. The hardfacing coating was found to have higher microhardness and higher abrasion resistance under a 10C atmosphere. This increase in mechanical properties is related to the microstructure, as the atmosphere using 10C promotes the formation of a higher quantity of hard phases, while the presence of CO induces the formation of higher volumetric fractions of eutectic phases, and, consequently, lower abrasion resistance is obtained.

Summary
Abrasive wear is the leading cause of premature mechanical failure in soil removal tools. Farmers are affected by the continuous manual labor downtime and the cost of replacing worn-out parts. These worn-out tools are less effective in cultivating the land, which implies higher production costs as well as emissions penalties [1]. Wear has been defined in different ways, most of which involve a process of material loss in which two surfaces slide against each other. Abrasive wear results in material loss due to the dynamic interaction of two surfaces against each other. The superficial removal of material from the surface results in dimensional losses. The lost material (material burr) causes an increase in the wear rate, which is achieved by the presence of the three bodies of abrasive wear, which is characterized by the relative motion of the abrasive particles over two phases in contact [3]
