“…Some of the advantages offered on those new Al-base components include: better wear resistance, strength to rupture [1][2][3][4] , modulus 5,6 , thermal stability 7 , among others. The aim of a composite material is to get a spectrum of properties that cannot be obtained by any of the constituent alone.…”

“…11,12 . Composites manufactured by the casting route 5,6,8 are usually challenging due to the different nature of the reinforcement that may have poor wettability and agglomeration problems 13 . Some reinforcements are highly reactive particularly at high temperature, which induce unwanted reactions between components 14 .…”

The present work deals with the study of some aluminum (Al) composites reinforced with metallized-graphite (MG) particles prepared by mechanical milling and powder metallurgy routes. Density, morphology evolution and mechanical performance of composites were investigated as a function of MG concentration and milling time. The as-milled powders were characterized by X-ray diffraction and optical/electron microscopy; meanwhile, the mechanical testing was carried out on cylindrical specimens prepared from powders by powder metallurgy. Evidence reveals that high-energy ball milling induce a homogeneous dispersion of graphite nanoparticles in the Al matrix; this is related to an enhancement of hardness and strength response of studied composites. The composite sample with 0.5% MG addition (in weight) reached an increase of 40% on hardness and 50% on strength (compared with pure Al sample); nevertheless an adverse effect was observed with longer milling and/or higher MG concentration.

“…[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Most studies [6][7][8][9][10][11][12][13][14][15][16] proved that SiC was more effective than Al 2 O 3 in the improvement of wear resistance of the resultant aluminum composite due to its higher hardness. [6][7][8][9][10][11][12][13][14][15][16] On the other hand, some investigations [17][18][19][20] suggested that Al/Al 2 O 3 composites were more stable and inert, and had better corrosion and high temperature behavior than Al/SiC. [17][18][19][20] In this sense, it may become practical to use both SiC particles and Al 2 O 3 particles (hybrid) as reinforcements to gain both of their benefits for improving the composite properties.…”

Aluminum-base hybrid composites reinforced with mixtures of SiC and Al 2 O 3 particles 1.25 mm in average size have been fabricated on an A 1050-H24 aluminum plate by friction stir processing (FSP) and their wear resistance has been investigated as a function of the relative weight ratios of the particles. A mixture of SiC and Al 2 O 3 powders of different weight ratios was packed into a groove of 3 mm width and 1.5 mm depth cut on the aluminum plate, and covered with an aluminum sheet 2 mm thick. A FSP tool of square probe shape, rotated at a speed of 1500 rpm, was plunged into the plate through the cover sheet and the groove, and moved along the groove at a travelling speed of 1.66 mm/s. After the hybrid composite was fabricated on the Al plate, the homogeneity of the particles distribution inside the Al matrix has been evaluated from the macro/microstructure and hardness distribution. Moreover, the wear characteristics of the resulted hybrid composites were evaluated using a ball-on-disc wear tester at room temperatures at normal loads of 2 and 5 N. As a result, it was found that the reinforcement particles were distributed homogenously inside the nugget zone without any defects except some voids that appeared around the Al 2 O 3 particles. The average hardness decreased with increasing the relative content of Al 2 O 3 particles. Regarding the wear characteristics, the wear volume losses of the hybrid composites depended on the applied load and the relative ratio of SiC and Al 2 O 3 particles. The hybrid composite of 80% SiC þ 20% Al 2 O 3 showed superior wear resistance to 100% SiC and Al 2 O 3 or any other hybrid ratios at a normal load of 5 N.
