“…The first factor is the Surface Finishing, Joint Configuration and Adhesive Thickness Control, the interaction of Joint Configuration and Adhesive Thickness Control, Surface Finishing and Joint Configuration, Joint Configuration, Surface Finishing and Joint Configuration and finally the thickness control. Additionally, the shear strength values presented some differences (2~10 MPa) with other authors that may be attributed to its chemistry (acrylic content, resin ratio and viscosity) and adherent (width, thickness, material and surface finishing) (Park et al, 2003;Shimizu, et al, 2014).…”

Surface roughening, joint configuration, and adhesive thickness were selected as factors to analyze, by using a 2 3 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 R 2 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 beads.Citation/Citar como: Cruz-González, C.E.; Mosquera-Artamonov, J.D.; Santillán, S.D.; Gámez-Cuatzin, H.

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 2 3 . 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 R 2 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. 2 • C. E. Cruz-González et al.

Superhydrophilic surfaces have attracted attention from more and more fields. Here, based on superhydrophilic coatings, insulating substrates are made temporarily conductive and suited for electrostatic powder coating (EPC). Furthermore, by manipulating surface wettability of the substrate, epoxy‐polyester powder particles are directly assembled into patterns in air under electrostatic attraction. First, electrically insulating substrates are treated to be superhydrophilic with composite nanoparticles of TiO2 and SiO2. Water droplets sprayed onto the surface could spread completely and connect together to form uniform thin water films (40 μm). The liquid films make the insulating surfaces conductive enough for EPC, which is an environmentally friendly coating process widely applied to conductive workpieces, such as metals. The first pass transfer efficiency (FPTE) is promoted to more than 80%, which is equal to or even greater than those of metal workpieces. Second, FPTE is quite different on surfaces with different wettability. Negatively charged epoxy‐polyester powder particles are attracted toward positively charged water film formed on superhydrophilic coatings. And few powders deposit on untreated nonconductive areas. Compared with electrostatic self‐assembly in solutions, this strategy is suited for rapid assembling various kinds of particles into large area patterns.

“…Thin polymer‐based coatings are useful for modification of surface properties, and may also serve as a primer layer with good adhesive properties toward a top coating . A particularly robust solution is provided if the adhesive polymer film is attached covalently to the substrate, thereby resulting in durable coatings of high stability in a broader range of applications .…”

A simple electrochemical approach based on potential sweeping has been developed for growing poly(phenylene sulfide) (PPS) brushes from 4,4’‐disulfanediyldibenzenediazonium salt on glassy carbon and stainless steel. First, the diazonium salt becomes reduced at the substrate on the initial part of the sweep carried out in a negative direction to form a covalently bonded diphenyl disulfide film. Once sufficiently extreme potentials are reached the disulfide bridges are reductively cleaved to form a thin layer of covalently attached thiophenolates. These are prone to be involved in fast coupling reactions with the diazonium salt to form PPS brushes in a repetitive growth process. In this manner linear PPS brushes with thicknesses up to 150 nm are easily formed. In addition, exact control on the brush length may be exerted through the switching potential selected or the number of sweeps applied. The films are characterized by time‐of‐flight secondary ion mass spectrometry which shows that the film growth is accompanied by an increase in the intensity ratio of S−/ normalS2− in line with the proposed PPS structure. This structure was further supported by Raman spectra, exhibiting a high‐intensity C−S stretch band and no S−S stretch band. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
