“…In another study, tungsten carbide was added, along with various amounts of calcium fluoride, and milling and compacting characteristic analysis were carried out to determine the transverse rupture strength. 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.…”

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.

“…They can possess high hardness, low coefficients of friction against materials such as steel, and are chemically inert [3][4][5]. The adhesive strength may have superior bonding, which allows an increase of the tribological characteristics [6][7]. Further, these coated surfaces promote a higher adhesive strength with an increased wear resistance corroborated with superior mechanical properties, corrosion resistance and bioactivity [8][9].…”

“…Plate speed and powder ball ratio was decided to avoid contamination. To understand the effect of solid lubricant on transverse rupture strength various weight percentages (0, 3, 5, 7 and 10) of CaF 2 were considered and milled up to 40 h. Detailed methodology was adopted for material development; evaluation of density, hardness, fracture toughness and transverse rupture strength of the cutting tool material with the various amount of solid lubricants have been reported elsewhere [19]. Table 1 listed out evaluated mechanical properties of developed cutting tool materials.…”
