Resumen
The In the present work, a comparative study is carried out to determine the resistance to abrasion of three types of cast irons. These materials are produced in the company Plant Mechanics of Santa Clara, taking for this study those of greater production, which are known as Fe 15, Fe 20 and Fe 30. A characterization of them is carried out, which includes chemical analysis, hardness measurement and structural analysis. To carry out the test, the method established in the ASTM G 65 standard known as the dry sand-rubber wheel is used. Method B of this standard is used, which has as working parameters the application of a force of 130 N, 2000 revolutions of the rubber wheel and a linear distance of 1436 meters. Finally, it is concluded that the highest resistance to abrasive wear coincides with the highest percentage of carbon and with the highest hardness of Fe 30
