“…Cemented carbides have replaced high-speed steels in metalworking and mining. Cemented carbides are metal-ceramic composites that consist of hard tungsten, titanium, and tantalum carbide grains located in a ductile matrix (binder) based on cobalt or nickel and have a unique combination of high hardness, wear-resistance, and toughness [10]. By now, a large number of cemented carbide grades have been developed, with diverse combinations of components both in the carbide phase and in the binder.…”

“…The hexagonal crystalline single layer of graphite (the simplest form and one of the most important crystalline allotropes of carbon atoms having a C•C bond distance of 0.142 nm) has received massive attention in the field of sensors, bio-medicals, composite materials and microelectronics. Thus, graphene is the strongest and best conductive material [19]. Graphene platelets or multi-layer graphene has been used as toughening additives to enhance the mechanical properties of various cutting tool materials [20].…”

Cutting is an important process in the manufacturing industry and cutting tool is an important element in machining. It is essential to use good quality cutting tools in arrange to maintain the quality of a product. To retain the performance of cutting tool, various techniques have been utilized like cutting fluid, cutting under MQL, coating, multilayer coating, cryoprocessing, different types of surface texturing, different types of solid lubricants, etc. All these processes have a great impact to enhance the mechanical, thermal, and tribological properties in case of conventional machining process. Nowadays composite engineered materials are very successful in metal cutting industry due to its wear-related application and excellent mechanical and thermal properties. A very few research has been carried out on graphene mixed composite tool material, which has very high demand in manufacturing industries, due to its application as a cutting tool material for machining of Al, copper, or high strength carbon steel. In the end, challenges in the processing of tungsten carbide graphene mixed self-lubricated tool have been identified from the literature. In parallel, the latest improvements to enhance the properties of tungsten carbide-cobalt cutting tool with graphene mixed are reviewed.

“…To increase the properties of coated layer, tungsten carbide was mixed with the other metal like cobalt and nickel in proportion to further increases the properties. However, the added metal resulted in the decreasing of properties like hardness, resistance, operating temperature [1]. WC coating had various applications in many different industries because of protection it provided against the wear at various different temperatures [9].…”

Corrosion and Wear, or a combination of both, are the main causes of degradation of metals used in the various industrial sectors. Degradation of the metals can be slowed down by adding a layer of resistant coating on the metal surface. This coating separates the base metal from a corrosive environment, reduces wear, and improves the appearance of the metal. The workpiece after coating becomes a composite that has properties far better than the substrate alone. There are various coating techniques, HVOF is one of the most important and widely used processes to protect the metals from wear, corrosion by providing hard and dense coatings. WC coating done by the high-velocity oxy-fuel (HVOF) spray method is the widely used method for providing a layer of corrosive resistance to a wide range of materials that are used in many different industries. In this study, Tungsten carbide (WC-12CO) Coating, HVOF Spray method was studied in great detail. Tungsten Carbide coating was done on a SUS400 Stainless steel substrate using HVOF Spray Process. An, Experiment was done to analyze the various effect of different parameters namely, oxygen rate, propane (fuel) rate, powder rate, spray distance on hardness, and surface roughness of a SUS 400 Stainless Steel substrate. Process optimization was done by using Taguchi and ANOVA methods. It was found that achieving maximum hardness was greatly dependent on propane (fuel) rate followed by powder rate, spray distance, and oxygen rate. The hardness decreases with the increasing fuel rate. And, achieving minimum surface roughness was greatly dependent on spray distance followed by oxygen rate, propane (fuel) rate, powder rate. Surface Roughness increases with increasing spray distance.

“…These properties make them most desirable materials for potential applications such as cutting tools, forming dies, and other wear applications [5]. Tungsten carbide (WC) is very desirable material due to its attractive mechanical, physical and chemical properties such as high hardness, high melting point, good electrical and thermal conductivity, and high corrosion resistance [6]. So, carbides used for thermal energy storage and release [7,8], enhancement the optical and electrical properties of polymers [9][10][11][12][13][14][15][16][17].…”

In this paper, novel shields for x-rays attenuation are synthesized by using poly-methyl methacrylate (PMMA), polystyrene (PS) and tungsten carbide (WC) nanoparticles. The prepared nanocomposites have light weight, high corrosion resistance, low cost and high attenuation. The effect of tungsten carbide on structural and optical properties of (PMMA-PS) blend was studied for x-rays shielding. The structural properties included the FTIR analysis and optical microscope images. The results showed that the fabricated nanocomposites have high absorbance for high energies which can be used for flexible electronic applications and flexible shielding. The absorbance, absorption coefficient, extinction coefficient, refractive index, dielectric constants and optical conductivity of (PMMA-PS) blend are increased while the transmittance and energy band gap are decreased with the increase in WC nanoparticles concentrations. The results of applications showed the (PMMA-PS-WC) nanocomposites have high attenuation for x-rays.
