“…Especially at 1400℃, the peeling of hardened layers is serious. It had resulted that materials with such high hardness would typically experience a brittle fracture in case the load exceeds their elastic limit [12]. When the processing temperature at 1200℃, although the peeling was not as obvious at the other processing temperatures, peeling also occurred.…”

Structure and mechanical properties of pure titanium by combined processing of boriding and nitriding with different processing temperatures in the heating furnace have been investigated. The effect of combined processing temperature for 2 h on the structure and mechanical properties of the treated specimens. As a result of the examination, combined processing at all designed temperatures resulted in the formation of titanium nitride, where the content of the nitride depended greatly on the processing temperature. When the processing temperature is 1300°C, the cross-sectional hardness of the hardened layer reaches the maximum. At the same temperature, the bonding strength also reaches the maximum, which is related to the performance of the hardened layer. Based on these results, when the processing temperature is 1300°C, the combined processing of pure titanium can improve the overall performance.

“…Whereas, for structured insert the laser ablation has altered the grain structure of insert that has subsidised the hardness (wear resistance property) of the insert [18]. Grigoriev et al [30] on TiN coating wear process explained that wear pattern of coating is brittle in nature with chipping of fragments of coating material. It was further explained that delamination between the layers of coating was also observed however, delamination does not transfer in to longitudinal cracks.…”

Tool wear is complex to predict due to the intricate environment of a machining process. However, there are a confrontational effect of tool wear on the machining process in terms of deprived surface finish, reduced dimensional accuracy and increased power consumption. In this study an attempt is made to examine the effect of rake face surface of the cutting tool on tool crater wear. For this, three different types; uncoated, coated and structured rake face cutting tools were used and cutting test were performed of plain carbon steel (AISI/SAE 4140). The cutting speed of 283 m/min, feed rate of 0.1 mm/min and depth of cut of 0.1 were used. Results show, structured rake face of the cutting tool benefitted most in supressing the tool crater wear. Energy-Dispersive X-Ray analysis (EDXA) analysis confirms reduction in iron transfer on tool rake face in case of coated and structured cutting tool. Micro − hardness test was also performed and the values in case of coated and structured cutting tool was found to be suffice. This study can be a benefit for cutting difficult to cut material where crater wear formation is unavoidable.

“…The application of the multilayer structure with a nanometric thickness of layers improves the properties of the coating, such as resistance to cracking and brittle fracture [51,52], as well as tribological properties [52]. Earlier studies of the coatings based on the (Cr,Mo,Al)N system (in particular, Ti-TiN-(Ti,Cr,Mo,Al)N [53], Cr,Mo-(Cr,Mo,Zr,Nb)N-(Cr,Mo,Zr,Nb,Al)N [11], and Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N [10]) proved their high efficiency as coatings for cutting tools.…”

This paper discusses the results of studies focused on the wear resistance, patterns of wear and plastic properties of Cr,Mo-(Cr,Mo,)N-(Cr,Mo,Al)N coating, containing 20 at.% Mo. The coating had a nanolayer structure with a modulation period λ = 50 nm. The studies revealed the hardness, fracture resistance in scratch testing, as well as elemental and phase composition of the coating. The studies of the tool life of carbide cutting tools with the Cr,Mo-(Cr,Mo,)N-(Cr,Mo,Al)N coating proved their longer tool life compared to that of uncoated tools and tools with the reference Cr-(Cr,Al)N coating of equal thickness and equal content of aluminum (Al). The studies included the comparison of the tools coated with Cr,Mo-(Cr,Mo,)N-(Cr,Mo,Al)N and Cr-(Cr,Al)N. The experiments focused on the specific features of the coating nanostructure and were conducted using a transmission electron microscope (TEM), revealing the different mechanisms of fracture. The penetration of particles of the material being machined between nanolayers of the coating results in interlayer delamination. When exposed to a moving flow of the material being machined, plastic deformation (bending) of the coating nanolayers occurs. The diffusion of iron into the coating (up to 200 nm) and diffusion of Cr and Mo into the cut material to a depth of up to 250 nm are observed. The presented information can help in the design of metal cutting tools and the choice of coatings for them.
