The article studies the tribological properties of multicomponent nanostructured coatings Zr-ZrN-(Zr,Cr,Al)N and Zr-ZrN-(Zr,Mo,Al)N, as well wear resistance fracture behaviour cutting tools with mentioned during turning Inconel 718 alloy. Ti–TiN-(Ti,Cr,Al)N coating was also considered a reference coating. While is characterized by high hardness, it demonstrated coefficients friction (COF) at te...

The influence of nickel on the structure and properties Ti-Cr-N ion-plasma coatings obtained by arc-PVD method has been studied. With a content up to 11.9 at. %, coating consists Cr 2 N, Ti1 – x metallic Ni. Upon further increase in Ni concentration coating, intermetallic compound Ni3Ti is formed. was studied using transmission electron microscopy. system are characterized columnar structure, c...

In the present study, CrN, TiN and (Ti, Cr)N coatings were deposited on D6 tool steel substrates. Physical and mechanical properties of coatings such as microstructure, thickness, phase composition, and hardness were evaluated. Phase compositions were studies by X-ray diffraction method. Mechanical properties were determined by nano-indentation technique. The friction and wear behaviour of the ...

Ni-20 wt pct Cr wires, as individual wires or within 3D woven structures, are alloyed with Mo, Al, and Ti by gas-phase surface deposition and volume interdiffusion. Mo deposition creates Mo-rich coating and Kirkendall pores. Al+Ti co-deposition creates uniform triple-layered coating. The resulting homogenized and aged Ni-(17.4-19.6)Cr-(1.6-1.8)Al-(2.5-3.6)Ti-(1.54.5)Mo(wt pct) wires exhibit c+ ...

The interface relationship between (Ti, Nb)(C, N) carbonitride and CeO2 was calculated by first-principles method. mechanism that as the nucleus of in Fe-Cr-C-Ti-Nb-N coating analyzed. microstructure hypereutectic Fe-Cr-C-Ti-Nb-N-CeO2 observed this paper. results show that, calculating phonon dispersion curves binding energy, most stable structure is Ti3NbCN3. two-dimensional lattice misfit Ti3...
