Resumen
En el presente trabajo se expone una evaluación de la tecnología de recuperación por soldadura aplicada en la EMI de Sancti Spiritus a las superficies desgastadas del aje de mando de la caja de velocidad del camión ZIL 131. En el trabajo se identifican y precisan las fallas típicas del eje de mando y se presenta, como resultado inicial, una caracterización del mismo en cuanto a la composición química, microestructuras y perfil de durezas del material, no conocidas con certeza y que permiten definir las propiedades necesarias a obtener durante la aplicación de una tecnología de recuperación. Se expone la caracterización de las propiedades del material aportado, esencialmente, en cuanto microestructura y perfil de dureza, a partir de muestras extraídas de una superficie recuperada en la empresa con material y tecnología actual. Los resultados demuestran que el método de recuperación no es adecuado y la tecnología y materiales aportados no garantizan las mínimas propiedades ni pueden garantizar la durabilidad deseada en la pieza. A partir de esos resultados, se recomiendan y fundamentan diferentes métodos o procesos tecnológicos de recuperación que pudieran ser aplicados con mejores resultados tecnológicos que la tecnología actual y que están al alcance de la empresa.
Presently work is exposed an evaluation of the recovery technology by welding applied in the EMI of Sancti Spiritus to the worn away surfaces of the one ages of control of the box of speed of the truck ZIL 131. In the work they are identified and they specify the typical flaws of the control axis and it is presented, as a result initial, a characterization of the same one as for the chemical composition, microestructuras and profile of hardness of the material, not well-known with certainty and that they allow to define the necessary properties to obtain during the application of a recovery technology. The characterization of the properties of the contributed material is exposed, essentially, as soon as microestructura and profile of hardness, starting from extracted samples of a surface recovered in the company with material and current technology. The results demonstrate that the recovery method is not adapted and the technology and contributed materials don't guarantee the minimum properties neither they can guarantee the durability wanted in the piece. Starting from those results, they are recommended and they base different methods or technological processes of recovery that could be applied with better technological results that the current technology and that they are within reach of the company.
