Abstract
In the mining industry, equipment deterioration due to abrasive wear can lead to reduced future revenue and to increase equipment availability, abrasion-resistant plates and linings are used. Hardox® steel is used in the manufacture of off-road truck weighbridges. With this in mind, this work proposed a study into the application of the hardfacing DIN 8555: MF 10-GF-60-GRZ in the areas with the highest incidence of wear on the truck body, as an alternative to protect the base metal to increase durability and, consequently, extend the lifespan of the equipment. The present study was intended to assess whether the material could be used to cover Hardox® 450 using the flux-cored arc welding (FCAW) process, in order to compare the performance of the plate with and without the covering in relation to abrasive wear. The methodology consisted of evaluating metallic properties, with chemical analysis, microstructure analysis, microhardness and a comparison of wear resistance using the pin-on-disk test. With the results obtained, it was possible to verify that the properties of the hardfacing were compatible with the base metal, so with its application it is possible to have good efficiency in the operation.
