Resistencia al desgaste de un acero A36 con dos recubrimientos

Abstract

Currently, there are numerous materials used in various fields of industry, and each one is selected according to the specific needs of the required application. For this reason, the following thesis aims to compare two coatings applied by electric welding (SMAW) on an A-36 structural steel, used as a base material. The purpose is to confirm the mechanical characteristics that ensure better performance in terms of durability, wear resistance, ductility and other mechanical properties compared to an uncoated material commonly used in the mining and agricultural industries. This analysis will be carried out by measurements through metallography and microstructure analysis tests and trials, which will allow the determination of hardness, coating deposition, microstructure and other characteristics such as roughness after wear testing. In addition, the amount of material shed shall be measured to verify the capabilities of the material by simulating working conditions in accordance with the standard abrasive wear measurement method specified in ASTM G65. These tests shall be carried out in a laboratory, avoiding critical environments with high corrosive levels, extreme temperature variations and other adverse conditions.
