Chemical and mechanical stability of air annealed cathodic arc evaporated CrAlON coatings

Thermal 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...

Mechanical properties and thermal stability of reactive arc evaporated Ti-Cr-Al-N coatings

This licentiate thesis reports experimental and theoretical work on the high temperature mechanical properties and the thermal stability of cubic (c)-(Ti-Cr-Al)1-N1 coatings. It is demonstrated that it is possible to tailor and improve the properties of hard nitride coatings by different degrees of multicomponent alloying. When Cr is added to Ti-Al-N the coatings exhibit age hardening up to 100...

Thermally enhanced mechanical properties of arc evaporated Ti0.34Al0.66N/TiN multilayer coatings

COMPARISON 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 ...

Characterization of TiN, CrN and (Ti, Cr) N Coatings Deposited by Cathodic ARC Evaporation

In this investigation PVD Ti-Cr)N coatings were deposited on hardened and tempered tool steel substrates using reactive arc evaporation. Physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and modulus young and coefficient friction were evaluated. Phase compositions were studies by X-ray diffraction method. The surface microstructure and morp...
