The Nb2O5-Ni coating was processed using DC sputtering on structural steel and study characterization of composite SEM/EDS inspection indicated clearly perfect incorporation Nb2O5 within the nickel rich. Increasing in surface roughness decreasing average diameters particles were obtained for coated compared with uncoated from AFM analysis, addition, microhardness test thickness showed that incr...

Modulated pulsed power magnetron sputtering (MPPMS) of titanium was investigated as a function argon gas pressure using optical emission spectroscopy (OES). Delays in discharge and the formation comb-like current waveforms due to splitting pulsing were observed with decrease pressure. This observation corresponds evolution from MPPMS condition deep-oscillation-magnetron-sputtering (DOMS)-like b...

We report the growth of high-quality AlN films on graphene. The graphene films were synthesized by CVD and then transferred onto silicon substrates. Epitaxial aluminum nitride films were deposited by DC magnetron sputtering on both graphene as an intermediate layer and silicon as a substrate. The structural characteristics of the AlN films and graphene were investigated. Highly c-axis-oriented ...

We report an interesting observation of minimization of bacterial attachment on titanium nitride coatings of increased thickness. DC magnetron sputtering method was used to prepare titanium nitride coatings of different thickness and the attachment of an oral bacteria Porphyromonas gingivalis was studied. With increase in thickness of the coatings the particle size increased and the order of ba...

Amorphous Ni–Ag films were obtained on liquid nitrogen cooled Si substrates using DC magnetron sputtering. A series of magnetic and magneto-transport property measurements confirm that the film with Ni to Ag atomic ratio of 60:40 is an alloy of the two elements immiscible in equilibrium, with atomic-level intermixing. The magnetic properties of the new alloy are discussed in comparison with tho...

The structure and nanoscale mechanical properties of Ni48.8Mn27.2Ga24 thin film fabricated by DC magnetron sputtering are investigated systematically. The thin film has the austenite state at room temperature with the L21 Hesuler structure. During nanoindentation, stress-induced martensitic transformation occurs on the nanoscale for the film annealed at 823 K for 1 hour and the shape recovery r...
