“…Fig.8 displays the EDX results of the worn surfaces of the stationary sample lubricated with EBO and EBO with graphite under different loads. It can be seen that, for pure EBO lubrication (Fig.8a), the carbon and oxygen on the worn surfaces could come from EBO decomposition [24], while the chromium might originate from the transfer from the AISI 304 stainless steel counterface [37]. The rubbed surfaces lubricated with EBO with graphite ( Fig.8b) had higher contents of carbon and oxygen than that lubricated by the pure EBO (Fig.8a), indicating that during the frictional process, the graphite can be exfoliated into graphene, and then some of graphene can be reacted onto the worn surfaces to form the complex tribo-film [38].…”

“…18 The effects of tungsten carbide and calcium fluoride addition were evaluated by assessing the friction and wear performance under abrasive and adhesive conditions. 19,20 According to the literature, sufficient investigations have been carried out to improve the wear resistance of cutting tools through texturing, coating, and the addition of solid lubricants. Based on the above literature, commonly used cutting tool materials, such as tungsten carbide and thermally stable calcium fluoride, have not been previously considered for the development of solid lubricant cutting tool materials.…”

Tungsten carbide cutting tools with and without solid lubricant (WC-10Co-5CaF 2 and WC-10Co) were developed inhouse via powder metallurgy. The developed cutting tools and a commercial WC-10Co cutting tool were used to machine cylindrical AISI 1020 steel material under dry conditions. The cutting force and average cutting tool temperature were continuously measured. The cutting tool flank surface and chip morphology after specific tool life (5 min of cutting) were examined to understand tool wear. The flank wear of the considered cutting tools was also measured to quantify the cutting tool life. The surface roughness of the workpiece was measured to determine the machining quality. The developed cutting tool with solid lubricant (WC-10Co-5CaF 2) generated 20%-40% less cutting force compared to that of the developed cutting tool without solid lubricant (WC-10Co). In addition, the finish of the workpiece surface improved by 16%-20% when it was machined by the solid lubricant cutting tool. The cutting tool with solid lubricant (WC-10Co-5CaF 2) exhibited a 15%-18% reduction in flank wear. Curlier and smaller saw tooth chips were generated from the WC-10Co-5CaF 2 cutting tool, confirming that less heat was generated during the cutting process, and the finish of the machined surface was also improved.

“…The restoration of ductility and toughness in the phases in the presence of Mn and Cr elements also occur. The microhardness value ascribed is due to a complex combination of deformation and elastic behavior of metal [32]. Here, it is clear that due to the presence of more martensitic phase, − 150 °C sub-cooled metal has a higher hardness.…”

“…In this paper, resistance to wear for all the cases in Table 2 was studied by measuring the loss in height of the pin for each sample by wear test rig of pin-on-disc type (Make: MAGNUM) with ASTM guidelines for different sliding velocities. This method has been adopted for abrasive wear test in recent times by various researchers and is referred in reputed journals [27,28,32,33]. This wear test uses a load cell and a linear variable differential transformer (LVDT) where vertical displacement of pin is automatically measured to compare different cases of metal.…”

In the present scenario, modernization of machine tool is the main objective to get the desired properties, so as to increase the tool steel life. In this research, we aim to improve the wear resistance of AISI P20 tool steel. Sub-cooling treatment is a simple technique that can extend the operational life of tool steel. In this study, P20 tool steel is treated at three different sub-cool temperatures. As the sub-cooled temperature decreases, the hardness and wear resistance of the metal increase significantly. The micro-hardness value of the − 150ºC sub-cooled metal is found in the range of 320-330 HV which is having 35% more hardness as compared to the as-received untreated metal. There is also 28% increase in the wear resistance of − 150ºC sub-cooled metal. The sub-zero temperature has shown its significant impact on microstructure, hardness and mechanical behavior of tool steel which directly improves the operational life of tool steel in the industrial environment.
