“…Multicomponent coatings based on nitrides of metals such as Ti, Al, Cr, Mo, Nb, and Zr were analyzed in a large number of studies. In particular, a number of studies have focused on the properties of the (Zr,Nb)N coating, in which a cubic fcc-(Zr,Nb)N mixed crystal phase has been detected as the dominant one [35][36][37][38]. The (Ti,Zr)N coating has also been investigated in a number of papers [39][40][41][42][43][44][45][46][47].…”

The paper presents the results of studies focused on the specific features typical for the formation of the shape and structure of microdroplets embedded into the structure of the Ti–TiN–(Ti,Cr,Mo,Al)N and Ti–TiN–(Ti,Al,Nb,Zr)N coatings during their deposition. Three main microdroplet shapes—a sphere, a tear, and a lens—have been considered. The specific features typical for the formation of secondary layered structures on the surface of some microdroplets have also been examined. As a result of the conducted investigations, with the use of scanning and transmission electron microscopy, the influence of microdroplets on the distortion of the nanolayer structure of the coatings was studied. A hypothesis has been proposed concerning a relationship between the microdroplet shape and the presence or absence of secondary structures and the microdroplet sizes and weight, as well as the conditions in the unit chamber during the movement of a microdroplet from a cathode to the deposition surface. Based on the study focused on the shape of the microdroplet core and the specific features typical for the formation of the secondary structure around it, a hypothesis has been proposed, according to which, for some microdroplets, it takes much more time than previously assumed for the movement from a cathode to the deposition surface.

“…At present, the most of the coatings widely used in industrial sphere are based on the TiN and (Ti,Al)N systems, as a rule, with the inclusion of additional elements, such as Cr, Mo, Y, Gf, Si, and others for the improvement of hardness, wear resistance, and heat resistance, which is very important [1][2][3][4][5][6][7][8][9][10]. Taking into account the fact that an enhancement of the cutting efficiency is an essential task of the modern manufacturing, while an increase in the cutting speed is a prevailing way to enhance the efficiency, the heat resistance is becoming an increasingly important property.…”

The paper presents the results of the investigation focused on the properties of the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N multilayered composite wear-resistant coating with a nanostructured wear-resistant layer. The nanostructure of the coating was investigated using transmission electron microscopy (TEM), the microhardness was measured, and the chemical composition was found. The cutting properties of a tool with the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N coating were studied during the turning of 09G2S silicon-manganese steel. It has been found that the use of a cutting tool with the Cr,Mo-(Cr,Mo)N-(Cr,Mo,Al)N coating reduces the flank wear rate by 1.65 times compared to an uncoated tool.

“…These lacks can be improved usually by deposing TiN, (Ti, Al)N, and (Ti, Nb)N hard films on the cutting tool surfaces. In order to further improve the comprehensive performances, hard reaction films has been developing toward multiple component films, multilayer composite films, gradient composition films [1,2].…”

(TiAlNb)N hard reactive films are prepared by multi-arc ion plating technology using the combination of Ti-50Al (at%) and Ti-25Nb (at%) alloy targets. The high speed steel (HSS) is adopted as substrate. The surface and cross-fracture morphology, the surface compositions and the phase structures of the as-deposited (TiAlNb)N films are observed and measured by scan electronic microscope (SEM) and X-ray diffraction (XRD). The mechanical properties including the micro-hardness, the adhesion between film and substrate, the thermal shock resistance of the as-deposited (TiAlNb)N films are systemically investigated. The effects of deposition bias voltage and the addition of Nb element on the as-deposited (TiAlNb)N films are discussed. The optimally comprehensive performances, especially hardness and thermal shock resistance, exhibited by (TiAlNb)N films with bias voltage of 100V.
