“…It is obvious that with the increase of silicon carbide content the specimen density decreases and the porosity increases. The regularities are compliant with the data obtained in another research where Cu-SiC composited were produced by mixing using the powder metallurgy method [1,2] and by mechanical alloying, but with a smaller silicon carbide content (up to 6 vol.%) [9]. The decrease in the composite density is conditioned by the fact that the density of SiC is much lower than that of copper.…”

“…Another reason is conductivity electron scattering. Cu/SiC interfaces, copper grain boundaries, as well as pores remaining after pressing are barriers for electron movement that provides for electrical conductivity [1,14]. It should be noted that all the specimens were compacted at the same pressure.…”

“…Copper matrix composites reinforced with SiC particles combine high electrical and thermal conductivity, enhanced hardness as well as a low coefficient of thermal expansion (CTE) [1][2][3][4]. Therefore these composites can be used in many application fields, including electronic packaging and electrical contacts.…”

In this study, the inuences of B4C ratios on some mechanical and physical properties such as relative density, microhardness and electrical properties of cold pressed Cu-B4C composites were investigated. Curve tting is applied for the estimation of electrical conductivity. Commercial copper powders with 40 µm particle size were reinforced with B4C, with particle size of 40 µm, at ratios of 1, 2, 3 wt.%, for improving mechanical properties of copper used as electrical conductor. Cu-B4C composites have been fabricated by powder sintering process at a temperature of 900• C for 2 h. The presence of Cu and B4C, which are dominant components in the sintered composites, were conrmed by X-ray diraction analysis technique and SEM-EDS. Scanning electron microscope (SEM-EDS) has shown that B4C particles are distributed homogenously in the copper matrix. The relative densities of Cu and Cu-B4C composites, sintered at 900• C, ranged from 95.7 to 91.6%. Microhardness of composites ranged from 84.5 to 94.6 HB. It was observed that cold pressed Cu-1 wt.% B4C composites revealed promising physical properties. Results of electrical conductivity measurement of Cu-B4C composite material are compared to the results of the model and the overall accuracy level above 96% is obtained.

“…The solid-state process curtails the reactions between the metal matrix and reinforcement, and thus augments the bonding between the reinforcement and the matrix. 19 The wear parameters, that control the friction and wear performance of reinforced Cu composites, can be classified into two categories: the physical (sliding speed, sliding distance, and normal load) and the material factors (weight fraction, size and distribution of reinforcements, and reinforcement/matrix interfacial bond). 20 Wear behavior of Cu MMCs has been studied and reviewed by many researchers.…”

In this experimental study, Cu-5 wt% Gr-X wt% SiC (X ¼ 0, 5, 10, and 15) metal matrix hybrid composites were successfully fabricated using solid-state mixing (powder metallurgy) technique through the conventional atmospheric sintering process. The effect of hard reinforcement SiC content on the microstructure, density, micro-hardness, wear resistance, and coefficient of friction of copper-based hybrid composites were investigated. The effect of the percentages of hard reinforcement, applied normal load (L), sliding distance (D), and sliding speed (V) on wear resistance and antifriction properties of composites were estimated at room temperature under dry sliding conditions using a pin-on-disc apparatus. The tribological test with an investigational plan of six applied loads (10-60 N), six sliding distances (500-3000 m), and five sliding speeds (0.5-2.5 m/s) were performed to record the loss in mass due to dry sliding wear. The result illustrated that the wear loss of the composite containing 15 wt% of SiC were superior to that of the other composites and unreinforced copper. The sintered cylindrical pins have been characterized by X-ray diffraction.Optical microstructural studies showed that the distribution of the hard SiC and soft graphite reinforcements were uniform on the copper matrix. The worn surfaces and wear debris of worn surfaces were analyzed through a scanning electron microscope to identify the type of wear mechanism involved in copper-based hybrid composites.
