“…In turning, much friction heat would be produced, which could prompt oxidation reaction. Literature [19] showed that Fe can react with O to form Fe x O y , Cr can react with O to form Cr 2 O 3 , Ti can react with O to form TiO 2 ; therefore, the oxides probably were Fe x O y , Cr 2 O 3 and TiO 2 , which could form an oxide film to protect the tool from further oxidizing. In machining, the oxide film would tear off and then regenerated, recurrently, which indicated that oxidation wear also occurred in the flank.…”

Cutting performances of TiCN-HfC (TH) and TiCN-HfC-WC (THW) ceramic tools in dry turning hardened AISI H13 was investigated. The optimal cutting parameterscutting speed of 110 m/min, feed rate of 0.1 mm/rev and depth of cut of 0.15 mmwere obtained by the orthogonal experiment. At the optimal cutting parameters, the tool life of TH was 82 min higher than that of THW, which indicated that TH had better wear resistance than THW. Meanwhile, the workpiece had better surface quality after turned by TH than by THW. In addition, a crescent depression formed in the rake face and a jackboot-like shape appeared in the flank. The rake face took place crater wear, while the flank took place abrasive wear, oxidation wear and adhesive wear.

“…The conventional tool materials, such as high-speed steel and cemented carbide, were inferior to ceramic materials as cutting tools. [13][14][15][16][17] Among the ceramic tools, sintered alumina ceramic (a-Al 2 O 3 ) based cutting tools remain the most prominent ceramic cutting tools available in the market due to their higher hot hardness temperature, robust abrasion resistance, and superior thermal and chemical resistance. 18,19 However, using pure alumina ceramics as cutting tool inserts operating under mechanical stresses and high temperature conditions is limited due to its poor strength and brittleness.…”

The Zirconia toughened alumina (ZTA) is the commonly used cutting tool material as it has superior mechanical properties. However, the poor tribological properties made it not suitable for dry machining. Various researchers added many additives to ZTA base tool to machine different workpiece materials for use in various applications. Still, it experiences many difficulties at various cutting speeds during machining. To overcome this, a novel composite tool was fabricated in the present study by adding the following self-lubricating elements such as, NiCr, Ag, Mo, SrSO4, and CaF2. The cutting performance was investigated by comparing the self-lubricating cutting tools (SLTs) with the base tool regarding cutting force, coefficient of friction, and surface roughness. The results showed that the addition of SrSO4 and Mo at 10 wt.% and CaF2 at 5 wt.% obtained superior mechanical and tribological characteristics. The generation of the following phase, viz., MoO3, Mo4O11, and Ag2MoO4, CaMoO4, and CaSO4, are responsible for the better performance. The additives restrained the transformation of t-ZrO2 to m-ZrO2 resulting in improved hardness and wear characteristics leading to strong protection of the self-lubricating layer formed on the tool flank surface, causes for performance improvement. The wear of the SLTs is primarily dominated by abrasion and adhesion, whereas the base tool is dominated by abrasion, adhesion, chipping, and cracking.

“…Mohanty et al found that friction coefficient showed decreased for increasing sliding velocity in case of Cr 3 C 2 -NiCr coating 36 . Wear rate and coefficient of friction (COF) for carbide based coatings reduced for increasing sliding speed while effect of load on COF and wear rate depends upon coating composition, wear mode and wear test parameters 19,35,[37][38][39] . a…”

Friction and abrasive wear response of WC-12 Co and Cr 3 C 2-25 NiCr coatings was studied. Abrasive wear experiments were conducted with SiC abrasive particles with varying load and sliding speeds. The results were analyzed using SEM, XRD and XPS observations of worn surfaces, wear debris and worn out abrasive paper. Friction coefficient diminished with rise in sliding speed and increased for increase in load while wear rates decreased for increasing sliding speed for both coatings. WC-12 Co coating had better wear resistance than Cr 3 C 2-25 NiCr coating while Cr 3 C 2-25 NiCr coating displayed lower friction coefficient. The variation in wear rate and friction response of coatings was due to combined effects of adhesion, abrasion and tribo oxidation effects. The composition of tribo films was strongly influenced by load and sliding velocity and altered friction and wear response of the coatings.
