| description | ABSTRACT:
Surface roughening, joint configuration, and adhesive thickness were selected as factors to analyze, by using a 23 design of experiments, the adhesive joint of AISI 430 steel using Methyl Methacrylate. Scanning electron microscopy observations, roughness-contour measurement and wettability analysis were performed on the adherents to analyze the adhesion, roughness, surface contour and shear strength on the adhesion tests. The statistical analysis yields that the most significant variable was the surface finishing for an adjusted R2 of 90%. The difference of shear stress of 20.69 and 12.67 MPa was obtained for the mechanical and chemical roughening respectively, since the difference in wettability was around 78 and 113° for the same surface finishing. According to analyze the combination of factors for a shear stress of 21.80 MPa are mechanical roughening, single lap joint and glass b eads.

RESUMEN:
Influencia del método de rugosidad, configuración de la junta y espesor del adhesivo sobre la resistencia al corte de superficies de acero inoxidable ferrítico unidas por metacrilato de metilo. Las variables rugosidad superficial, configuración de la junta y espesor de adhesivo fueron seleccionadas para analizarlas mediante un diseño de experimentos 23. La unión adhesiva se realizó en una junta de acero ASI 430 utilizando Metil metacrilato como adhesivo. Para analizar la adhesión, rugosidad, contorno superficial y resistencia al corte se realizaron observaciones en el Microscopio Electrónico de Barrido, mediciones de rugosidad-contorno y mediciones de humectabilidad sobre los adherendos. El análisis estadístico arrojó que la variable más significativa fue el acabado superficial generando una R2 de 90%. Una diferencia de 20,69 y 12,67 MPa se obtuvo para los acabados superficiales mecánico y químico debido a una diferencia en humectabilidad expresada por ángulos de contacto de 78 y 113° respectivamente. Con base al diagrama de Pareto, la combinación para obtener el esfuerzo de 21,80 MPa fue el acabado mecánico, junta de bisel simple y perlas de vidrio.
