Nanocomposite Nb-Al-N coatings: Experimental and theoretical principles of phase transformations

“…Low thermal stability and oxidation resistance are among the main disadvantages of such coatings. Addition of impurities to the crystal lattice of the transition metal nitrides form nanostructured coatings with improved properties [25][26][27][28][29][30][31][32]. Ternary nitrides, such as Ti 1-x Al x N, Zr 1-x Al x N and Cr 1-x Al x N have higher hardness, oxidation resistance and thermal stability in comparison with binary CrN, ZrN and TiN coatings [33][34][35][36][37][38][39][40][41][42][43].…”

Composition, structure and tribotechnical properties of TiN, MoN single-layer and TiN/MoN multilayer coatings

“…The microstructures and elemental compositions of coatings were studied using several electron-ion scan ning microscopes (Quanta 200 3D, Quanta 600 FE SEM) equipped with a detector of X ray radiation of the PEGASUS 2000 system (EDAX, USA) [26][27][28][29][30][31]. We used also a JEOL 7001F scanning electron microscope (Japan) with a microanalysis by the energy dispersive X ray spectroscopy (EDX).…”

“…For the investigation of mul tilayer coatings and determination of their thickness, we prepared crosscut thin sections. The coatings struc tures and phase compositions were analyzed by X ray diffraction analysis (XRD) in a CuK α radiation (Bruker Advanced 8, DRON 3M) [31,32]. The degree of the texture perfection, Δψ, was defined from the width on a half height of a diffraction line taken at the θ scanning [31][32][33][34][35].…”

A separation of diffraction profiles in the case of their overlapping was performed by the New_profile computer program of the separation overlapping lines, which was developed at the NTU Kharkiv Polytechnic Institute.…”

Structural features and physico-mechanical properties of AlN-TiB2-TiSi2 amorphous-like coatings

“…Its structure is represented by an amorphous matrix of silicon nitride with imbedded into it TiN nanocrystalls. This coating is characterized by hardness > 40 GPa, high resistance to oxidation (850°C) and high thermostability (up to 1100°C) [6][7][8]. Later a TiAlSiN fourcomponent nanocomposite coating was produced and studied.…”
