“…Due to the development of the furniture industry, the demand for new tool materials has increased in recent years, providing increasingly higher machining parameters and improved performance. The researchers’ works are focused mainly on improving the cutting and strength properties of WC-Co carbides, by: hard coating, ion implantation or development of new composite materials based on WC-Co [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Despite all efforts of materials engineering, the “ideal tool material” has not yet been developed.…”

The paper presents the effect of diamond particle size (varying between 2.5 µm and 20 µm) on the microstructure, density and hardness of WC-Co/diamond composites. The obtained materials contained 30% vol. diamond. The advanced sintering method Pulse Plasma Sintering (PPS) was used for the production of composites. The sintering process was carried out in two stages at a pressure of 50 and 100 MPa and a temperature of 1050 °C. Depending on the size of the diamond particles, composites with a density of 91–99% were obtained. Microstructure studies were performed employing scanning electron microscopy, along with an analysis of the chemical composition in micro-areas. Additionally, the phase composition was investigated by means of X-ray diffraction. In addition, hardness tests were performed. It was found that the size of the diamond particles significantly influenced the microstructure of the tested materials, as well as the density and hardness. As a result of PPS sintering of composites containing the finest diamond particles (2.5–5 µm), the presence of a metastable type of diamond—graphite was found.

“…The deposition of composite electrochemical coatings (CECs) is a reliable and economically feasible method for modifying metal surfaces in order to impart new functional properties to them [1][2][3]. Among the CECs, coatings based on nickel [4][5][6][7][8][9][10][11][12] and its alloys [13][14][15][16][17][18][19][20][21][22] have become widespread, which is due to the ability of nickel to form electrolytic deposits with dispersed particles of different nature which have good adhesion to the metal base [4]. It should be noted that the electrochemical deposition of alloys is one of the special cases of parallel electrode reactions with their significant mutual influence.…”

“…The effectiveness of the practical application of CECs is largely determined by the nature and properties of the dispersed phase. Currently, composite coatings modified with various carbon materials are widely studied: nanodiamonds [9], fullerenes [4], carbon nanotubes [10], carbides [8,12], etc. Graphite and its derivatives are of particular interest as dispersed phases used in the preparation of CECs.…”

Electrodeposition of Graphene Oxide Modified Composite Coatings Based on Nickel-Chromium Alloy

Composite electrochemical coatings (CECs) based on nickel-chromium alloy and modified with multilayer graphene oxide (GO) were obtained. The electrodeposition process of these coatings was studied in the potentiodynamic mode. The structure and the composition of nickel–chromium–GO CECs were studied by scanning electron microscopy and laser microspectral analysis. Nickel–chromium–GO CECs are dense and uniform. The carbon content in them increases when moving from the substrate to the surface. It was established that the addition of GO particles into the composition of electrolytic coatings with a nickel-chromium alloy results in the increase in their microhardness from 4423–5480 MPa to 6120–7320 MPa depending on the cathodic current density.

“…Tungsten carbide is also used in armor-piercing ammunition and for making surgical instruments, for open surgery and laparoscopic surgery, giving better performance than other materials. 3,4 In addition, it is commonly utilized for manufacturing the gauge blocks, producing precision lengths in dimensional metrology. 2 To extend their industrial applications and to produce bigger and/or more complex tools, it is necessary to join WC-Co to metals to create high strength, tougher and impact-resistant structure in the final assembly, as the tungsten carbide is an extremely brittle material.…”

Tungsten carbides are extremely high in hardness and they are wear-resistant materials. However, they are extremely brittle materials that render them ideal for many applications. Brazing technology has been proved to be a promising approach for joining tungsten carbide to tough metals to create high strength, tough and impact-resistant joint in the final assembly. In this research work, a dissimilar brazing of tungsten carbide (WC-Co) and cold work steel will be achieved using a new type of filler, a silver-copper near-eutectic alloy (BAg-8T) (Ag70Cu28Ti2). (BAg-8T) as a mixed alloy (eutectic and titanium) can melt/solidify completely in a very narrow temperature range (778 °C/800 °C), lower than any other existing brazing filler alloy; this will reduce the possibility of partial fastening while solidification. In addition, (BAg-8T) filler will act as the soft-iron gauze. Being soft and ductile metals, they will creep and absorb the movement due to differential contraction of the carbide and tool shank. Besides, they will improve the wetting on the carbide. In this research work, the effect of the joining parameters (brazing temperature and cobalt percentage in the tungsten carbide) on the mechanical properties and microstructure of the brazed joint will be investigated to determine the best joint performance.
