“…A wide range of nanoparticles are used as reinforcement, among which the most common are: aluminium oxide (Al 2 O 3 ), silicon carbide (SiC), boron carbide (B 4 C), titanium carbide (TiC) and titanium oxide (TiO 2 ) [2][3][4]. The addition of SiC nanoparticles to aluminium alloy matrix results in improvement in strength, hardness [5] and corrosion resistance [6]. The main advantage of using the nanoparticles reinforcement is that improved properties can be achieved with a smaller amount of reinforcement compared to the macroparticles reinforcement [5,6].…”

The optimization of wear rate of the nanocomposites with A356 aluminium alloy matrix, reinforced with silicon carbide nanoparticles, was performed through the analysis of the following influences: wt% of the reinforcement, normal load and sliding speed. The nanocomposites were produced by the compocasting process with mechanical alloying preprocessing (ball milling). Three different amounts of SiC nanoparticles, with the same average size of 50 nm, were used as reinforcement, i.e. 0.2, 0.3 and 0.5 wt%. Tribological tests were performed on block-on-disc tribometer (line contact) under lubricated sliding conditions, at two sliding speeds (0.25 and 1 m/s), two normal loads (40 and 100 N) and at sliding distance of 1000 m. Analysis of variance (ANOVA) was applied to determine the influence of different parameters on wear value of tested nanocomposites. It was noticed from ANOVA analysis that normal load, with 33.39%, is the most significant factor affecting the wear rate of nanocomposites. The amount of reinforcement, with 28.90%, also has a significant influence on the wear rate, while the influence of sliding speed, with 23.82%, is smaller. It was found that the prediction of wear rate, by using regression model and Taguchi analysis, were close to the experimental values.

“…Aluminum metal matrix composites (Al-MMCs) are increasingly used in automobiles, high-speed trains, subways and airplanes due to their low density, high specific strength, low coefficient of thermal expansion and cost effectiveness [1][2][3][4][5][6]. Over the past few decades, several methods have been developed to prepare Al-MMCs, such as stir casting [7][8][9][10], powder metallurgy [11][12][13][14] and pressure infiltration [15,16]. However, flawless and uniform Al-MMCs are still difficult to achieve, which severely restricts their property advantage and industry applications [1,17].…”

Relatively low compactness and unsatisfactory uniformity of reinforced particles severely restrict the performance and widespread industry applications of the powder metallurgy (PM) metal matrix composites (MMCs). Here, we developed a combined processing route of PM and equal channel angular pressing (ECAP) to enhance the mechanical properties and wear resistance of the SiC p /Al-Si composite. The results indicate that ECAP significantly refined the matrix grains, eliminated pores and promoted the uniformity of the reinforcement particles. After 8p-ECAP, the SiC p /Al-Si composite consisted of ultrafine Al matrix grains (600 nm) modified by uniformly-dispersed Si and SiC p particles, and the composite relative density approached 100%. The hardness and wear resistance of the 8p-ECAP SiC p /Al-Si composite were markedly improved compared to the PM composite. More ECAP passes continued a trend of improvement for the wear resistance and hardness. Moreover, while abrasion and delamination dominated the wear of PM composites, less severe adhesive wear and fatigue mechanisms played more important roles in the wear of PM-ECAP composites. This study demonstrates a new approach to designing wear-resistant Al-MMCs and is readily applicable to other Al-MMCs.nanostructured Al/SiC-graphite composite by accumulative roll bonding (ARB) and showed that a homogeneous ultra-fine grain structure and uniform distribution of particles could be obtained by eight ARB cycles. Haghighi et al. [18] revealed that the Al-5 vol.% nano-Al 2 O 3 composite consolidated by equal channel angular pressing (ECAP) possessed higher mechanical properties and hardness. In addition, twist extrusion (TE), as a potent tool for obtaining advanced engineering materials, can be used to improve the mechanical and tribological properties of MMCs [22,23].The tribological property is crucial to components sustaining wear. As important wear-resistant materials, Al-MMSs have been employed for vehicle discs. The optimized microstructure, especially the refined matrix grains, and improved mechanical properties of Al-MMCs by SPD lead to enhanced wear resistance. It was suggested that through the grain refinement, the wear-resistance of MMCs and some alloys can be improved to follow a linear relation with the d −0.5 (d is the average grain size), resembling the Hall-Petch effect [24][25][26][27]. However, there have been very limited reports in the literature dealing with the wear behavior of SPD-MMCs up to date, and among a few publications, there were conflicting results reported. Haghighi et al. [18,28] compared the Al-MMCs processed by ECAP or conventional extrusion and concluded that the ECAP samples possessed better wear resistance than the extruded counterparts. The improved wear resistance was attributed to pore elimination, homogeneity of the particle distribution and grain refinement by the ECAP. Similarly, enhanced wear resistance of Al-MMCs by ARB was reported by Darmiani [29]. However, decreased wear resistance was also reported by Jamaati et al. [26], who...

“…In addition to the types of reinforcements, the corrosion behavior of composites is also affected by the reinforcement content. It has been found that the corrosion rate of the composites decreases with the increase of the content of reinforcing materials [18,19].A great deal of work has been done on the thermophysical and mechanical properties of Diamond/Cu composites. However, systematic work on the corrosion behavior and property evolution of Diamond/Cu composites has not yet been carried out.…”

Corrosion Behavior of Pressure Infiltration Diamond/Cu Composites in Neutral Salt Spray

Diamond particle-reinforced copper matrix composites (Diamond/Cu) are recognized as promising electronic packaging materials due to their excellent thermophysical properties. It is necessary to investigate the reliability of Diamond/Cu composites under extreme environmental conditions. The corrosion behavior of Diamond/Cu composites was studied in a 5 wt% NaCl neutral salt spray. Surface morphology, thermal conductivity, bending strength, corrosion rate, and corrosion depth resulting from corrosion were researched in this paper. The results showed that the corrosion phenomenon mainly occurs on the copper matrix, and the diamond and interface products do not corrode. The corrosion mechanism of Diamond/Cu composites was micro-galvanic corrosion. The corrosion product formed was Cu2Cl(OH)3. The salt spray environment had a great influence on the composite surface, but the composite properties were not significantly degenerated. After a 168-h test, the bending strength was unaltered and the thermal conductivity of gold-plated composites showed a slight decrease of 1–2%. Surface gold plating can effectively improve the surface state and thermal conductivity of Diamond/Cu composites in a salt spray environment.
