“…These are unique properties of B 4 C, which at room and high temperature make it a key material for various high technology applications, such as fast-breeders, neutron moderators in nuclear reaction, power generation in deep space ight applications, microelectronic, medicinal, light-duty bulletproof armors, blasting nozzles, abrasive water-jet cutting equipment, high temperature thermoelectric devices, high-temperature structural parts, cutting tools, rocket propellants, wear-proof parts and thermo-mechanical applications [10]. In the present study B 4 C was selected as reinforcement for its superior mechanical properties of high hardness, high anti-wear stiness during grinding operation, high electric conductivity to comply with the IACS's electrode standard, and high thermal conductivity, to obtain higher thermal shock resistance.…”

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.

“…However, the oxidation temperature and time must be carefully controlled in case of excessive consuming of B 4 C particles. for Cu crystals to nuclear on the surface of B 4 C particles [10,17]. Besides, these new surfaces with a complex microstructure are generated by a chemical method rather than physical method.…”

“…It was demonstrated that Cu-coated ceramic particles can effectively improve the wettability between ceramic particles and molten aluminium [9]. Besides, Due to its high thermal conductivity and non-reaction with B 4 C at high temperature, Cu coating is chosen as a suitable metallic coating [10].…”

“…There was uniformity in the observed copper coating in alkali-treated particles at a level of pH-12, when matched to others. This is due to the effective elimination of impurities during the processes of production and processing of commercially existing B 4 C [62]. The electroless Cu-PSiC composite coating on carbon steel improved the anti-corrodibility behavior of deposits of electroless Cu [63].…”

Electroless metallic coating is referred as the deposition of a substrate material by the process of chemical or autocatalytic reduction of aqueous metal ions deposited to a substrate material without any external supply of power. Electroless nickel alloys are generally considered synonymous to the word "electroless coating" as ~90% of productions in industries are of this alloy coating. Rest of the electroless metallic coatings includes gold, copper, palladium, cobalt, silver, etc. These electroless metallic coatings (other than electroless nickel coatings) are also one of the vibrant areas in the field of materials properties and surface engineering research. From the year 2000 to till date, nearly 1000 SCI indexed research papers were published on this topic. However, no comprehensive studies about the recent progress on this topic were reported elsewhere so far. In this context, the present chapter aims to give a complete overview on various aspects of the rest of the electroless metallic nanocoatings/layer as a whole. More importance will be on the recent developments of the nanocharacteristics and future scopes.
