“…[4][5][6] D reinforced metal matrix composites, in particular, are frequently used in cutting tools, wear-resistant coatings, and electronic packaging materials. [7][8][9] However, because of their poor wettability, D and metal are difficult to obtain a strong interface bonding, making it difficult to improve the properties of composites. [10] Therefore, to improve the performance of composites, it is necessary to improve the interface bonding state between D and metal.…”

To obtain a high‐quality TiC coating on the diamond (D) surface and improve the interfacial properties of metal matrix composites, the optimized molten salt method is used to prepare TiC coatings on the D surface. The effects of NaCl, KCl, and NaCl–KCl molten salts on the uniformity, surface morphology, composition, and bonding ability of TiC coatings are investigated by scanning electron microscopy, energy‐dispersive X‐ray spectroscopy (EDS), X‐ray diffraction, and cold–hot cycling experiments. The results show that the boiling and pickling processes after the molten salt reaction can effectively remove the residual chloride salts and Ti powders to obtain clean TiC‐coated D. The TiC particles of the coating surfaces prepared by NaCl and KCl molten salts are finer and more uniform, which is due to their higher melting points and shorter real reaction time compared with NaCl–KCl mixed salts. The TiC coating prepared by KCl has the best bonding ability and can withstand 50 times as many cold–hot cycles due to its uniform fine deposition particles and appropriate thickness. And, during cold–hot cycles, it can be found that the TiC coating cracking and shedding occur primarily at the edges and corners of the D with internal thermal stress concentration.

“…It is applied to the use of WC in composite coatings [ 9 ], coatings on high-strength steel [ 10 ], and coatings for tribotechnical purposes [ 11 ]. Furthermore, the use of WC is actively studied for the tasks of diamond tool making [ 12 ], as one of the components of the filler of matrices of high hardness materials based on the diamond [ 13 ] and in the composition of the diamond film [ 14 ].…”

Spark Plasma Sintering of WC-Based 10wt%Co Hard Alloy: A Study of Sintering Kinetics and Solid-Phase Processes

et al. 2022

View full text Add to dashboard Cite

The paper describes the method for producing WC-10wt%Co hard alloy with 99.6% of the theoretical density and a Vickers hardness of ~1400 HV 0.5. Experimental data on densification dynamics, phase composition, morphology, mechanical properties, and grain size distribution of WC-10%wtCo using spark plasma sintering (SPS) within the range of 1000–1200 °C are presented. The high quality of the product is provided by the advanced method of high-speed powder mixture SPS-consolidation at achieving a high degree of densification with minimal calculated grain growth at 1200 °C.
