Fabricación de un material funcionalmente graduado mediante la máquina de colado centrífugo horizontal del laboratorio de fundición de la Escuela Politécnica Nacional : Fabricar un material funcionalmente graduado con matriz de aluminio y refuerzo de partículas cerámicas.

Abstract

The objective of this project is to characterize a functionally graded material or Functionally Graded Material (FGM) with an aluminum matrix and reinforcement of Silicon Carbide (SiC) particles. The manufacture of the FGM will be carried out considering specific parameters such as the speed of rotation of the mold of the centrifugal casting machine, temperature of the molten material, size of the SiC particles (#400 mesh), percentage by weight of the particles and mold temperature; Once these parameters are defined, the material will be manufactured using the horizontal centrifugal casting method. It is worth mentioning that the equipment to be used is the Stir Casting equipment, a machine with a centrifugal force casting mold and a gas oven. these equipment’s are available in the foundry laboratory of the Escuela Politécnica Nacional. For the manufacturing process, an Al 365 alloy will be used that will be melted in a gas oven (LPG) with a capacity of 5kg, during the casting process fluxes will be placed to eliminate any type of impurity during the process, then the silicon carbide ceramic particles will be added and once the casting has the required parameters, the material will be poured into the horizontal rotating mold at a speed of 1200 rpm, previously said mold must be preheated to a temperature of 400 °C to obtain a tube with a functionally graded structure. Finally, the specimens taken from the manufactured tube will be characterized by metallographic analysis and the micro-hardness in the areas that characterize a functionally graded composite material will be measured.
