Abstract:
In the scenario of industrial production systems, there is a challenge related to the losses of components caused by abrasive wear. Abrasive wear causes a high number of unexpected interruptions in machinery operating in processes especially when the raw material contains abrasive elements, such as minings processes. In this way, this research carried out a comparative analysis of the abrasive wear suffered by SAE 1020 steel lubricated with metal conditioner and lithium-based grease. To carry out this comparative analysis, an Abrasometer was used, which follows the standards of the ASTM G65-16 standard. This equipment performs tests with standardized parameters that simulate the abrasive wear process. The test carried out comprises four distinct stages: the characterization of the steel and abrasive, the preparation of the specimens, the weighing of the specimen, the preparation of the abrasive, and the calibration of the equipment. The results demonstrated that the metal conditioner did not have a lower wear rate than lithium grease. Thus, for mechanical equipment that has interaction and relative movement, the lithium-base grease is equal to the performance of the metal conditioner. Both offer good resister abrasive wear
