“…For example, GN, GO, and RGO attracted attention in cutting technologies. The addition of GN improves the performance of polycrystalline diamond compact (PDC) [157]. Therefore, a high-performance GN/PDC composite was prepared, and the hardness, wear-resistance, and electrical conductivity improved significantly, comparing to the pure PDC material.…”

Carbon nanomaterials with a different character of the chemical bond—graphene (sp2) and nanodiamond (sp3)—are the building bricks for a new class of all-carbon hybrid nanomaterials, where the two different carbon networks with sp3 and sp2 hybridization coexist, interacting and even transforming into one another. The extraordinary physiochemical properties defined by the unique electronic band structure of the two border nanoallotropes ensure the immense application potential and versatility of these all-carbon nanomaterials. The review summarizes the status quo of sp2 – sp3 nanomaterials, including graphene/graphene-oxide—nanodiamond composites and hybrids, graphene/graphene-oxide—diamond heterojunctions, and other sp2–sp3 nanocarbon hybrids for sensing, electronic, and other emergent applications. Novel sp2–sp3 transitional nanocarbon phases and architectures are also discussed. Furthermore, the two-way sp2 (graphene) to sp3 (diamond surface and nanodiamond) transformations at the nanoscale, essential for innovative fabrication, and stability and chemical reactivity assessment are discussed based on extensive theoretical, computational and experimental studies.

“…For example, graphene, GO, and RGO attracted attention in cutting technologies. For example, the addition of graphene also improves the performance of polycrystalline diamond compact (PDC) [137]. A new type of high-performance diamond composite PDC-G was prepared and compared with PDC without graphene; the hardness and wear resistance of PDC-G with 0.1 wt% graphene addition were enhanced by 75% and 33%, respectively.…”

Carbon nanomaterials with a different character of the chemical bond – graphene (sp2) and nanodiamond (sp3) are the building bricks for a new class of all-carbon hybrid nanomaterials, where the two different carbon networks with the sp3 and sp2 hybridization coexist, interact and even transform into one another. The unique electronic, mechanical, and chemical properties of the two border nanoallotropes of carbon ensure the immense application potential and versatility of these all-carbon graphene – diamond nanomaterials. The review gives an overview of the current state of the art of graphene – diamond nanomaterials, including their composites, heterojunctions, and other hybrids for sensing, electronic, energy storage, and other applications. Also, the graphene-to-diamond and diamond-to-graphene transformations at the nanoscale, essential for innovative fabrication, and stability and chemical reactivity assessment are discussed based on extensive theoretical, computational, and experimental studies.

“…Baker Hughes invented graphene-coated diamond particles, the polycrystalline composite cutter was sintered by adding catalysts or other materials between the diamond particles, but the preparation process was complicated and it was difficult to realize [19]. Jilin University studied a method for preparation of diamond composite cutter containing graphene, by adding graphene and cobalt powder into diamond micro-powder, the gap between diamond grains was filled, and the wear resistance and impact toughness of PDC cutter were improved, but this method still relies on the addition of cobalt as a binder, which cannot avoid the adverse effects of cobalt [20,21]. However, these research ideas can provide important inspiration for the research of this paper.…”

In order to improve the wear resistance, impact toughness and other comprehensive properties of PDC cutter, a new type of graphene-enhanced PDC cutter was developed by taking advantage of the excellent mechanical and thermal properties of graphene. Through the research of raw material treatment, diamond micro powder ratio, cemented carbide substrate structure and synthetic sintering process, three kinds of PDC cutters with graphene mass percentage of 0,1 wt%, 0,2 wt% and 0,3 wt% were prepared respectively. SEM tests showed that the binder distribution of PDC cutters with graphene mass percentage of 0,1 wt% and 0,2 wt% is relatively uniform, and there are no graphene agglomeration phenomenon occurred. Heat resistance tests showed that the heat resistance of the PDC cutter with graphene mass percentage of 0,2 wt% is the highest. Abrasion resistance tests showed that the wear ratio of the PDC cutter with graphene mass percentage of 0,2 wt% is the highest. Impact resistance tests showed that the impact energy of the PDC cutters with graphene mass percentage of 0,2 wt% and 0,3 wt% is the highest, and the impact resistance energy is over 2500 J. The Multiple Attribute Decision Making method was used to select the best graphene added scheme, and the PDC cutter with graphene mass percentage of 0,2 wt% shows the best comprehensive performance. The real drilling test was carried out in the Baiping Coal Mine of Zhengmei Group, the concave drill bit with 0,2 wt% graphene added PDC cutters showed the fastest average ROP, the least cutter wear, and the best drilling effect.
