RESUMEN En este trabajo se realiza la descripcion del fenomeno de erosion en un recubrimiento multicapas de fases ductily fragil, expuesto a impactos sucesivos de particulas solidas. Mediante simulacion numerica se represento elfenomeno erosivo y se mostraron los resultados por medio de una animacion, tablas y graficas en la cual se visualizoen tiempo real los diferentes perfiles de espesor formados en un recubrimiento. Ademas, se creo un escenario desimulacion que genera un recubrimiento con distribucion aleatoria de granos de refuerzo WC (Carburo Wolframio)con caracteristicas diferentes para cada simulacion. La simulacion permitio al Ingeniero Metalurgico encargadode crear el recubrimiento, obtener informacion del mismo y dar una idea de que tipo de distribucion inicial debiatener este con concentraciones %WC. A su vez permitio al Ingeniero Metalurgico observar como fue la tendenciade deterioro de este recubrimiento a medida que el tiempo de exposicion aumenta. Palabras clave: Simulacion, Fenomeno de Erosion, Modelo Base Ajustado, Recubrimiento Multicapa. ABSTRACTIn this paper it is described the phenomenon of erosion in a multi-layer coating of ductile and brittle phases whenexposed to successive impacts of solid particles. By numerical simulation was performed the erosion phenomenonand results were shown by means of an animation, tables and graphics with different profiles of thickness that it getformed in the coating and that are visualized in real time. However, a simulation scene can be created in which acoating with distribution of reinforcement grains WC (tungsten carbide) with different characteristics is generatedfor each simulation. The simulation allowed the metallurgical engineer that is in charge of creating the coating,obtain information about it and give an idea of the type of initial distribution of the coating that must have this withthe concentrations of %WC. In turn it allowed the metallurgical engineer observe as was the deterioration tendencyof this multi-layer coating as the exposure time increases. Keywords: simulation, phenomenon of erosion, adjusted base model, multi-layer coating.
