This article presents the data set obtained for research work entitled "Effect of a Ni-P coating on corrosion resistance an additive manufacturing carbon steel immersed in 0.1 M NaCl solution" [1]. Microstructural, mechanical, and electrochemical characterization (using impedance noise spectroscopy technique) is performed material by influence it. The layer sizes hardness substrate are measured, as well thickness its hardness, values resistance, to location indices calculated. show adequate...
La proyección térmica o rociado térmico es una tecnología que implica calentar un material está en forma de polvo alambre y llevarlo a estado fundido semifundido, para luego propulsarlo mediante corriente gas aire comprimido depositarlo sobre sustrato metálico, cerámico polimérico, tenga condiciones rugosidad adecuadas. investigación realizó la caracterización electroquímica las técnicas espectroscopia impedancia ruido electroquímico aleación Zn-15Al depositada fundición nodular grado...
This article brings together various experiences aimed at achieving a better understanding of learning by students through the application simple and easy experiments, oriented especially to what Phase Component concepts represent in an alloy system, so that they can approach topic Diagrams their Materials (Science, Engineering, Technology) courses with background. Thus, are presented allow, initially, recognize, solute solvent concepts, distinguish unsaturated , saturated, supersaturated...
In the last decade, magnetic nanomaterials have been widely used in fields of chemistry, physics, engineering, and medicine due to their optical, magnetic, conductive properties, as contrast agents resonance. Their influence treatment cancerous tumors has evaluated sparked great interest its use environmental repair systems such absorbers that trap metal particles some contaminants. Here we analyze process parameters obtain nanoparticles under three chemical synthesis methods. Its...

Las capas depositadas,...
Additive metal manufacturing has undergone a revolution in recent years, being able to be incorporated several industries such as aeronautics, automotive and even medicine, allowing the manufacture of complex parts with fewer steps process, which translates material savings cost reduction. In this work, corrosion low carbon steel obtained by depositing consecutive layers is carried out, using electrochemical impedance spectroscopy noise immersed 0.1 M NaCl solution, establishing comparison...
In this work, it was studied the by-products of fly ashes, obtained from a thermoelectric power station in Boyacá, Colombia, through magnetic separation. The morphological characterization particles performed by scanning electron microscopy. Its elemental composition and crystalline structure were energy dispersive spectroscopy an X-ray diffraction, respectively. results show presence ferrospheres cenospheres, which are irregular rough compounds with high iron content. mineralogical phases...
This text describes the plasma nitriding of a ductile iron, to increase surface hardness and improve its wear behavior. A ferritic iron was used processed with gases (N2 + H2) for 5 hours in treatment chamber built at UNAM Physics Institute. The treated samples were characterized using scanning electron microscopy, atomic force microhardness X-ray diffraction. presence Fe-N compounds corroborated on material. Modifications morphology 30% also obtained.
