UV- and VIS Filter Coatings by Plasma Assisted Reactive Magnetron Sputtering (PARMS)

Decorative Titanium Nitride Colored Coatings on Bell-Metal by Reactive Cylindrical Magnetron Sputtering

The transition metal nitrides like titanium nitride exhibit very interesting color variation properties depending on the different plasma deposition conditions using cylindrical magnetron sputtering method. It is found in this deposition study that nitrogen partial pressure in the reactive gas discharge environment plays a significant role on the color variation of the film coatings on bell-met...

Development and characterization of a secondary RF plasma-assisted closed-field dual magnetron sputtering system for optical coatings on large-area substrates

An RF-assisted closed-field dual magnetron sputtering system was developed to characterize the plasma and the ionization fraction of sputtered material to provide a suitable system for depositing optical thin films on large-area substrates at low temperatures (<130 ◦C). The ‘prototype’ system consists of dual 76 mm dc magnetrons operated at both balanced and unbalanced (closed-field) configurat...

Synthesis and characterization of La2NiO4+δ coatings deposited by reactive magnetron sputtering using plasma emission monitoring

Photocatalytic Activity of Reactively Sputtered Titania Coatings Deposited Using a Full Face Erosion Magnetron

Titanium dioxide (titania) is widely used as a photocatalyst for its moderate band gap, high photoactivity, recyclability, nontoxicity, low cost and its significant chemical stability. The anatase phase of titania is known to show the highest photocatalytic activity, however, the presence of this phase alone is not sufficient for sustained activity. In this study TiO2 coatings were deposited on...

Photocatalytic Properties of Doped TiO2 Coatings Deposited Using Reactive Magnetron Sputtering

Mechanically robust photocatalytic titanium oxide coatings can be deposited using reactive magnetron sputtering. In this article, we investigate the effect of doping on the activity of reactively sputtered TiO2. Silver, copper and stainless steel targets were used to co-deposit the dopants. The films were characterised using XRD, SEM and EDX. Adhesion and mechanical properties were evaluated us...
