The continuous development of modern industries rises the necessity for functionally graded materials. This research starts from the consideration that the incorporation of SiC particles in the molten aluminum alloy can be difficult due to the very low wettability of SiC particles. In order to increase their wettability, SiC particles were covered with a layer of metallic copper. The incorporation of SiC particles into the aluminum alloy mass was performed by centrifugal casting. The secondary hypoeutectic Al-Si alloy used in this study was elaborated within the crucible of a resistors heated furnace. The metallic coating of SiC particles, in addition to the effect of increasing their wettability by molten metal, also has a role in preventing the formation of aluminum carbide in case of heating above 700 °C. A great amount of attention was paid to the parameters used during the centrifugal casting process. The results showed that adjusting the proportion of SiC particles within the composite allows us to obtain values of the thermal expansion coefficient within previously established limits. The present work demonstrates that the coating of SiC particles covered with a thin layer of metallic Cu creates the conditions to easily incorporate them into the molten Al mass, thus obtaining FGMs with controlled properties.

“…The construction and commissioning of high and medium power concentrated solar ovens since 1950, but especially after 1970, (when the large 1MW solar furnace was put into use in Odeillo, France) opened new directions for research on the processing possibilities of materials with high energy flows and very high temperatures [1,[3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Solar energy is already widely used for water heating and electricity production. Attempts to process materials with solar energy have been made since the 17th and18th centuries. The construction of high and medium power concentrated solar furnaces in the late 20th century opened new perspectives in this direction. Lately, the possibilities of processing materials by using this energy are being researched more and more, together with the construction principle and the features of the operation of solar furnace with concentrated energy. Based on the knowledge gained in research conducted worldwide by various authors, including the University of Transilvania in Brasov, an analysis is made of the advantages and limitations of various processing of materials in such ovens, taking into account the possibilities of application at the industrial level.
