“…Decreasing the size of the carbon material to the micro-level can reduce the starting temperature of the reaction to 750 °C [16]. Reducing the size of carbon particles to the nano-level leads to a further decrease in the starting temperature of the aluminum carbide formation: when using nanodiamonds, carbon onions or fullerenes, the temperature of the beginning of the chemical reaction decreases to 300 °C-400 °C [18][19][20].…”

The possibility of applying globular carbon for reinforcing the aluminum matrix when using mechanical alloying to produce composites was shown by investigating specific properties of chemical interaction of nanocarbon with the aluminum matrix. The structure of the initial particles of globular carbon and composite granules was studied. Mechanical alloying can significantly crush the initial particles of globular carbon. The use of the method of differential scanning calorimetry allowed the temperature of the start of the reaction between globular carbon nanoparticles and aluminum matrix with the formation of aluminum carbide to be determine as 320 °C-350 °C. Aluminum matrix composites with reinforcing particles of globular carbon can be used up to these temperatures without risk of the formation of aluminum carbide.

“…That is why designing methods for fabricating carbides of various metals during the direct chemical reaction between the metal and carbon is a vital task. The opportunity to decrease the carbide synthesis temperature when using carbon nanoparticles as precursors has been studied in several works: articles show that the use of carbon nanoparticles (nanodiamonds [9,32], fullerenes, carbon onions [6], globular carbon [3]) in aluminum matrix composites leads to the synthesis of aluminum carbides at significantly lower temperatures than in the case of macro-materials: when fullerenes are used, the decrease reaches 350 • C. This effect was also investigated when using chromium as a composite matrix with nanodiamond reinforcing particles [33]. The temperature was reduced to 520 • C. Studies of using this effect for the synthesis of refractory metal carbides are important, since the existing methods of producing such carbides use high temperatures.…”

Metal matrix composites with a matrix of refractory metals (niobium, tungsten) and reinforcing nanodiamond particles were prepared for studying the possibility of decreasing the starting temperature of carbide synthesis. The size of primary nanodiamond particles was 4–6 nm, but they were combined in large-sized agglomerates. Mechanical alloying was used for producing the composites by crushing agglomerates and distributing nanodiamonds evenly in the metal matrix. The initial and fabricated materials were investigated by X-ray diffraction, differential scanning calorimetry, and transmission and scanning electron microscopy. Thermal processing leads to the reaction for carbide synthesis. Studies have found that the usage of carbon nanoparticles (nanodiamonds) as precursors for fabricating carbides of refractory metals leads to a dramatic decrease in the synthesis temperature in comparison with macro-precursors: lower than 200 °C for tungsten and lower than 350 °C for niobium.

Several Aspects of Interaction between Chrome and Nanodiamond Particles in Metal Matrix Composites When Being Heated

The paper considers the development of a technological scheme for preparing metal matrix nanocomposites based on the interaction between nanodiamond reinforcing particles and a chromium matrix when being heated, forming chromium carbide nanoparticles. These carbides are in situ synthesized ceramic reinforcing nanoparticles. The first stage of preparing composites is to obtain composites with the chromium matrix and nanodiamond reinforcing particles. For this purpose, mechanical alloying is used, i.e., processing in planetary mills. The size of a primary nanodiamond particle is 5 nm, but they are combined in agglomerates that are hundreds of micrometers in size. The time of processing in the planetary mill defines the crushing degree of the agglomerates. In this study, processing was carried out for 0.5 h, 2 h, and 4 h. The second stage for obtaining composites with reinforcing particles of chromium carbides is thermal processing. Explorations using the method of differential scanning calorimetry showed that reducing the size of nanodiamond reinforcing particles (by prolonging the time of processing in the planetary mill) leads to a decrease in the initial temperature of the reaction for developing carbides. The worked-out technique for obtaining composites was patented in the Russian Federation (the patent for invention 2772480).
