Thermal factor effect on phase formation, structure, substructure features, and stress state in ion-plasma nano-crystalline condensates of quasi-binary WC-TiC carbide
Using high-angle X-ray diffraction and X-ray fluorescence spectral analysis, the effects of the sputtered material composition and deposition temperature on the phase and elemental composition, structure, substructure features, and stress state in the ion-plasma quasi-binary WC—TiC coatings. The inc...
