This paper reports on the preparation of titanium nitride (TiN) thin films on carbon steel plates, using cathodic arc evaporation CAE PVD technique. We studied and discussed the effect of various nitrogen gas flow rates on microstructural and mechanical properties of TiN-coated carbon steel plates.

the response after some penetration depth is given not onlyby the films but also by the substrate and, the mechanicalproperties obtained are a combination of the true values ofthe films and the structure. Indentation with contact depthsof less than 10% of films thickness is needed to obta[r]

The BiFeO3(BFO) thin film was deposited by pulsed-laser deposition on SrRuO3(SRO)-buffered (111) SrTiO3(STO)substrate. X-ray diffraction pattern reveals a well-grown epitaxial BFO thin film. Atomic force microscopy studyindicates that the BFO film is rather dense with a smooth surface.[r]

= Where σf is total film stress, θ is Bragg diffraction angle, E is Young modulus, υ is Poisson coefficient. ∆(2θ) will get a minus value if the total film stress is compressed stress [23]. Thus due to this thermal stress, in order to survey WO3, we have combined the results from both XRD and Raman[r]
