Reconstituted nanostructured powders were plasma sprayed using various processing conditions to produce nanostructured alumina–titania coatings. Properties of the nanostructured coatings were related to processing conditions through a critical plasma spray parameter (CPSP) that in turn, can be related to the amount of unmelted powder incorporated into the final coating. Those coatings that reta...

Combined effects of plasma seed treatment and activated waters (PAW) application on paddy was explored. Low pressure (100 torr) glow oxygen discharge (LPGOD) used for germination test revealed that 90s duration produced highest ~96% which is the rate obtained through technology. Plasma water prepared with submerged atmospheric air jet. PAW sprayed 1-5 times to plants. Field study divulged that:...

Suspension plasma spraying has become an emerging technology for the production of thermal barrier coatings for the gas turbine industry. Presently, though commercial systems for coating production are available, coatings remain in the development stage. Suitable suspension parameters for coating production remain an outstanding question and the influence of suspension properties on the final c...

Highly scattering plasma-sprayed thermal barrier coatings (TBCs) present a challenge for optical diagnostic methods to monitor TBC delamination because scattering attenuates light transmitted through the TBC and usually degrades contrast between attached and delaminated regions of the TBC. This paper presents a new approach where reflectance-enhanced luminescence from a luminescent sublayer inc...

Plasma-sprayed ceramic coatings are being developed for many applications such as thermal barriers and corrosion protection. In plasma spraying, the ceramic powder is heated into semi-molten droplets for projection onto a target surface by a high velocity gas stream. This coating is then rapidly cooled to form a solid layer. By repeating this process for multiple layers, a coating thickness fro...

Additive manufacturing is an emerging disruptive 3D printing technology that stimulating innovations in design and engineering, materials, thanks to the prospects of reducing cost waste increasing efficiency; doing so, it presents potential have marked industrial, economic, societal impacts. Thermoplastic polymers show some ideal characteristics for most common additive methods, this aids impro...
