Within this work the effect of B content on microstructure, phase composition and mechanical properties CVD Ti(B,N) coatings is investigated. with contents from 0 (fcc-TiN) to ∼5, ∼15, ∼30, ∼45 66 (h-TiB2) at.% have been deposited by CVD. The elemental was confirmed ERDA their microstructure investigated using XRD SEM. With increasing content, a transition fcc h-dominated structure via dual-pha...

Transition metal diborides are ceramic materials with potential applications as hard protective thin films and electrical contact materials. We investigate the possibility to obtain age hardening through isostructural clustering, including spinodal decomposition, or ordering-induced precipitation in ternary diboride alloys. By means of first-principles mixing thermodynamics calculations, 45 ter...

Innovation in material science progresses the usage of Al2O3/SiC based nanocomposites gas turbine engine components, harp-shaped structure hypersonic rocket cutting tools for Ni, Al alloys, and clutch plate two-wheelers. Thermal stability is one significant properties materials. Future engines may have to operate at very high temperature that require thermally stable material. In this research,...
