“…[6] Recently, aluminum matrix composites with particle reinforcements, in the forms of coating and bulk free-standing material, have been also obtained by this process. [7][8][9][10][11][12][13][14][15] The reinforcements used in the composites include SiC, Al 2 O 3 , and TiC particles, as well as short graphite fibers. Iiyuschenko et al [8] used Al and Al-Si powders mixed with 55 to 75 vol pct SiC or TiC particles as feedstock materials to produce plasma-sprayed Al-carbide and AlSi-carbide coatings.…”

Air plasma spraying was used to produce Al-SiC p composites as electronic packaging material. Ballmilled Al with 55 and 75 vol. pct SiC powders was repeatedly deposited onto a graphite substrate, and then mechanically removed to get free-standing 100 ϫ 100 mm composite plates of about 2-mm thickness. Different input electrical powers were employed at two spray distances of 100 and 120 mm. The SiC volume fraction and porosity in the sprayed composites were found to be dependent on spray conditions, especially input electrical power. Maximal SiC volume fraction can be obtained at a low input electrical power for the composite sprayed from the Al-55SiC powder and a high input electrical power for Al-75SiC powder. The variation of the SiC level in the composites with spray conditions and SiC size is discussed based on the characteristic of feedstock, the characteristic of deposited surface, and the heat and momentum transfer between particle and plasma flame. Pores in the sprayed composites were found inside one sprayed layer (inner-layer pore) and at the boundary between two sprayed layers (interlayer pore). The formation mechanisms of two types of pores are also explained. X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses indicate that Si phase is formed in the sprayed composites for most spray conditions. The Si resulted from the decomposition of SiC particles in high-temperature plasma flame.

“…This low DE obtained when Al/SiCp blends are used as powder feeder, has been previously described by some authors using plasma or HVOF as thermal spray process [2,14,21,22]. In thermal spray processes such as plasma or HVOF, the feedstock powders prepared by blending SiC with metallic particles (i.e.…”

“…[1] At present, particle-reinforced metallic matrix surface composites are mainly prepared by centrifugal casting, electromagnetic separation, laser cladding, plasma spraying processing, friction stir processing, etc. [2][3][4][5][6] However, due to the high density and high specific surface energy of reinforced phase or particles, and the bad wettability existing between the reinforced phase and the metallic melt, reinforced phase particles are apt to sedimentation or conglomeration, and their strengthening effect on the matrix is weakened.…”

A novel surface modifying technique, ultrasonic coupling processing (UCP), was developed to fabricate the TiAl 3 particle-reinforced Al matrix surface composite. The effects of UCP on the microstructures and wear resistance of the Al matrix surface composite were investigated. The results show that the TiAl 3 particles are driven toward the sound pressure node by the acoustic radiation force coupled with a low intensity ultrasonic field. The reinforced particles move toward a definite direction in the stable stationary field under the ultrasonic coupling condition. The hardness of the surface composite takes on a graded distribution due to the distribution of TiAl 3 particles along the longitudinal direction. The interface between the matrix and reinforced phase bonds well, and the wear resistance of the composite increases significantly.
