Structure, hardness and thermal stability of Ti(Al,N) coatings
In the past two decades, coatings of the Ti–Al–N ternary system have attracted considerable research and industrial interest. Nevertheless, the Ti–Al–N system still offers new interesting possibilities for coating developments such as the addition of low N contents to Ti–Al films in order to reach a good compromise between high hardness and a low friction coefficient. Ti–Al–N coatings with low ...

متن کاملDevelopment of Al-Ti-N Composite Coatings on Commercially Pure Ti Surface by Tungsten Inert Gas Process
The present work aims to modify surface properties of pure Ti by development of Ti-Al-N intermetallic composite coatings. In this regard, tungsten inert gas (TIG) cladding process was carried out using Al 1100 as filler rod with Ar and Ar+N2 as shielding gases. Phase and structure of the samples were investigated by X-ray diffraction (XRD) technique, optical microscopy (OM) and scanning electro...
متن کاملCOMPARISON OF THE CrN , TiN AND (Ti, Cr)N PVD COATINGS DEPOSITED BY CATHODIC ARC EVAPORATION
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 ...
متن کاملThermal stability and mechanical properties of arc evaporated Ti–Al–Zr–N hard coatings
a r t i c l e i n f o Based on previous reports, showing that zirconium alloying to Ti 1 − x Al x N hard coatings can increase their thermal stability, we study in detail the interaction of bias potential and Al content on structure, hardness, thermal stability, and oxidation resistance of arc evaporated Ti 1 − x − y Al x Zr y N hard coatings. For moderate Al-contents, Ti 0.49 Al 0.44 Zr 0.07 N...
