Abstract
The aim of this research is to produce composite materials with ceramic base covered by a layer of (Al) and its alloys by means of fused deposition technique. This technique represents new method and combines the powder technology with the casting technique. Al2O3 poweder was used after having been pressed by different pressure(58,117 and 176 MPa) in metal molds. The sintering process has been preformed at 1100 o C for two hours. After that, the porosity percentage has been measured and the samples were immersed in the molten metals heated to 700o C . Ultirnatly, these samples were heated to about 1000 o C by a furnace for half an hour. Then,the samples were cooled to 650 oC and examined by an optical microscope and the scanning electron microscope. Moreover, the x-ray diffraction for these sample has been employed to define the structure of the resulting composite as well as to define the resulting bond between the deposited metal layer and the ceramic matrix in addition to characterize the existing phases within the composite material.
