“…Generally, the temperature of the graphitization process is affected by the type of binder [ 143 , 144 ]. TiC coatings on diamond particle surfaces limit the graphitization process of diamond in the tools, which is accelerated by the Fe (the catalyst of diamond transition into graphite [ 145 ]).…”

The Critical Raw Materials (CRMs) list has been defined based on economic importance and supply risk by the European Commission. This review paper describes two issues regarding critical raw materials: the possibilities of their substitution in iron-based alloys and the use of iron-based alloys instead of other materials in order to save CRMs. This review covers strategies for saving chromium in stainless steel, substitution or lowering the amounts of carbide-forming elements (especially tungsten and vanadium) in tool steel and alternative iron-based CRM-free and low-CRM materials: austempered ductile cast iron, high-temperature alloys based on intermetallics of iron and sintered diamond tools with an iron-containing low-cobalt binder.

“…Metallic binders that possess high affinity with carbon, like Co, Fe, Ni accelerate the graphitization process. 12) Wetting of diamond surface with metal matrix is governed by the nature of their bonding with diamond. Bonding mechanism between diamond and metal matrix may be either mechanical or chemical or a combination of both.…”

“…27) To achieve high adhesion between diamond and Fe matrix, coating of diamond particles with TiC has been reported by Luciano Jose de Oliveira and co-workers. 12) The chemical adhesion between TiC and Fe matrix is due to the formation of Fe-Ti solid solution during hot pressing. Roughness of coated diamond grits also improve the mechanical adhesion as compared to smooth surface of uncoated diamond.…”

In recent years, people are committed to developing new technologies and technologies for energy storage and conversion, environmental detection, high-performance sensors and energy security, and other aspects of the increasingly prominent problems in the field of environmental and biosafety. The purpose of this paper is to explore the manufacturing system and automatic synthesis equipment of carbon nanomaterials, understand the control device and control method, and analyze the structure and morphology characteristics of three kinds of carbon nanomaterials produced by carbon nanomaterial manufacturing system by X-ray diffraction and infrared spectroscopy. The results show that the carbon nanomaterial manufacturing system and automatic synthesis system in this paper solve the problems of high cost, low efficiency, and small scale of the existing carbon nanomaterials manufacturing and achieve the precision control of automatic production, so that the productivity is increased by 20%–35%, and the cost is reduced by 15%–30%. Therefore, they are widely used in the fields of science and technology, environmental protection, and intelligent manufacturing broad prospects. Carbon nanotube manufacturing equipment and automatic synthesis equipment have great production advantages, which can greatly improve the quality and efficiency of carbon nanomaterials. UPY, GO, and UGO carbon nanomaterials produced by carbon nanotube manufacturing equipment are not easy to fall off from the materials. When the wavelength is 500 nm, the absorption frequency of the three materials is the largest. With the extension of the spectral wavelength, the absorption frequency of the three materials is reduced by 52%, 33%, and 34.7%, respectively.
