“…Therefore, it is critical to determine coating composition and specific process technology, which are best suited to any particular tool under specific operating conditions. PVD technology is gaining increasing market share owing to its ability to deposit thin coating (micrometre to nanometre), low deposition temperature (450 o C and below) and better coating properties [25][26]. It has been estimated that in 2007 globally 56% of cutting tools are coated by PVD technology as compared to 20% in 2000 [27].…”

The benefits of applying advanced coatings on both single point and multipoint cutting tools such as improvement of productivity, tool life, machined surface quality etc. have been realised environments. This is because the end performance of coated cutting tools is not only dependant on the coating itself but also on the substrate material, geometry, surface finish and cutting edge conditions prior to coating deposition. The paper presents case studies with examples of successes and failures of advanced coatings on different multipoint cutting tools (e.g., milling cutters, bandsaws, circular saws, holesaws etc.). The future strategy for developing successful coating technology for cutting tools should be directed towards adopting a systems approach to bridge the communication gap amongst the cutting tool manufactures, tool coaters and end users.

“…In 1969, a few microns thick titanium carbide TiC coatings were developed using chemical vapor deposition (CVD) technique to prevent the cutting tools start to oxidize at low temperatures [6]. During the last three decades transition metal nitrides and carbides have been developed as prominent hard coating materials as they offer extremely hard surfaces, low friction coefficient, excellent adhesion, favorable sliding characteristics, and relatively high electrical and thermal conductivity.…”

This thesis is a theoretical exploration of properties of multilayered and multicomponent nitride alloys, in particular their mixing thermodynamics and elastic behaviors. Systematic investigation of properties of a large class of materials, such as the multicomponent nitride solid solutions, is in line with the modern approach of high-throughput search of novel materials. In this thesis we benchmark and utilize simple but efficient methodological frameworks in predicting mixing thermodynamics, Young's moduli distribution of multilayer alloys and the linear thermal expansion of quaternary nitride solid solutions.We demonstrate by accurate ab-initio calculations that Ti 1−x Al x N solid solution is stabilized by interfacial effects if it is coherently sandwiched between TiN layers along (001). For TiN/AlN and ZrN/AlN multilayers we show higher thermodynamic stability with semicoherent interfaces than with isostructural coherent ones.Accurate 0 Kelvin elastic constants of cubic Ti x X y Al 1−x−y N (X=Zr, Hf, Nb, V, Ta) solid solutions and their multilayers are derived and an analytic comparison of strengths and ductility are presented to reveal the potential of these materials in hard coating applications. The Young's moduli variation of the bulk materials has provided a reliable descriptor to screen the Young's moduli of coherent multilayers.The Debye model is used to reveal the high-temperature thermodynamics and spinodal decomposition of Ti x Nb y Al 1−x−y N. We show that though the effect of vibration is large on the mixing Gibbs free energy the local spinoal decomposition tendencies are not altered. A quasi-harmonic Debye model is benchmarked against results of molecular dynamics simulations in predicting the thermal expansion coefficients of Ti x X y Al 1−x−y N (X=Zr, Hf, Nb, V, Ta).v Sammanfattning Denna avhandling är en teoretisk undersökning av egenskaperna hos multilager och multikomponentlegeringar av nitrider, särskilt deras blandningstermodynamik och elastiska egenskaper. Systematiska undersökningar av egenskaperna hos en stor materialfamilj, såsom fasta lösningar av multikomponentnitrider, ligger i linje med den moderna angreppsvinkeln av massundersökningar i sökandet efter nya material. I denna avhandling utvärderar och använder vi enkla men effektiva metodologiska ramverk för att förutsäga blandningstermodynamik, fördelning av Young's moduli multilager och den linjära termiska expansionen i kvaternära fasta lösningar av nitrider.Vi visar med precisa ab-initio-beräkningar att en fast lösning av Ti 1−x Al x N stabiliseras av gränssnittseffekter om den placeras koherent mellan TiN-skikt längs med (001). För multilager av TiN/AlN och ZrN/AlN påvisar vi högre termodynamisk stabilitet med semikoherenta gränsskikt än med isostrukturella koherenta. Precisa elastiska konstanter vid 0 K för kubiska fasta lösningar av Ti x X y Al 1−x−y N (X=Zr, Hf, Nb, V, Ta) och deras multilager beräknas och en analytisk jämförelse av deras hållfasthet och duktilitet presenteras för att visa dessa materials potential ...

“…By doing coating on the tools, machining become easy as they offer greater wear resistance and deformation under high speed machining. In 1969 introduced the first coated cemented carbide index able inserts for turning (Soderberg et al 2001).. Hard substances like TiN TiC and Al2o3 are also used for coating as they improve the cutting tool capabilities. AS a result, the tools can cut at higher speed with reduced power consumptions (Watmon et al 2010).…”
