Resumen: La corrosión causa grandes pérdidas y daños catastróficos en plantas industriales y en la infraestructura. Entre los métodos para reducirla se encuentran los recubrimientos. El uso de recubrimientos multicapa metal-cerámico es eficiente para disminuir la corr

Abstract: Corrosion causes great losses and catastrophic damages in industrial plants and infrastructure, among the methods to reduce it are the coatings. The use of metal-ceramic multilayer coatings to reduce corrosion in steels is a viable option, since they offer se

Abstract: A method is presented to obtain the orientation curve in the Eulerian space, of crystallites which diffract in one point of a Debye-Scherer ring in a second diffraction process. The incident beam is therefore the reflected beam of a previous diffraction proce

Abstract: We have computed accurate values for the ground state energy of a hydrogen atom confined by a finite spherical barrier of height V0 as a function of the confinement radius Rc. We consider the nucleus as a sphere with a uniform charge distribution instead of a

Abstract: Non-linear thermal radiation effects on non-aligned stagnation point flow of Maxwell fluid have been carried out in the present investigation. It is observed that the non-linear radiation augments the temperature and heat transfer rate. This physical phenomen
