Abstract

This research addresses the urgent challenges facing the materials and metallurgical industries, driving manufacturers to seek innovative solutions for material recycling. Aluminum scrape in used to manufacture a composite material with a high mechanical properties and good corrosion resistance to be suitable material for fabrication of automotive spare parts. Al scrape in melted at 800 oC, then reinforced with 5, 10 and 15 % from the hybrid Alumina – GNS composite powder prepared by mechanical milling technique by 1:10 ball to powder ratio 350 rpm for 24 hr. To solve the non-wettability problem between the hybrid ceramic reinforcement with the melted Al scrape, it was coated with 10% nano Ag by electroless chemical deposition technique. A vortex method was used to used, in which a mechanical string with 600 rpm for 10 minutes was achieved. Roman spectrum analysis confirmed the flack structure of the GNS. Both hardness and wear resistance were improved by the gradually increasing of (Al2O3-GNS) percentage. The microstructure also achieved a good and homogeneous distribution of the reinforcements in the Al matrix and the good Ag coating process. The corrosion rate was decreased by increasing the (Al2O3-GNS) rates.
