Several investigations have been devoted towards understanding the coating process in fluidized beds. Most of these studies focused on spraying liquid droplets over the bed. However, due to the complexity of these systems, more investigations are still required to quantify the effect of operating conditions on the coating criteria. The present work aims at fundamentally understanding and pr...

Physicochemical and insecticidal properties of fenitrothion microcapsule (MC) as a new residual spraying formulation for mosquito control were studied. The wall staining after treatment with MC at the rate of 1-2 g AI/m2 was not noticeable as compared with that of wettable powder (WP). Covering rate with MC on a vertical wall was almost the same as WP and emulsifiable concentrate (EC) when the ...

Multi-electrode plasma torches are becoming increasingly popular in the thermal spray community due to their good stability and high power plasma jet even when operated with inert gases. Currently the models in use feature either three cathodes and a single anode or three individual anodes connecting to a single cathode. The motivation for development of these plasma torches is based on the inh...

Metallic glass has excellent functions such as high strength and high corrosion resistance. Therefore, it is one of the most attractive materials, and various developmental research works have been conducted by many researchers. However, the metallic glass material is expensive to use, and a composite material is preferred for the industrial application. Thermal spraying method is one of potent...

A highly dense Ni59Zr20Ti16Si2Sn3 partial amorphous metallic coating, about 500mm thick, was fabricated by means of HVAF (High Velocity Air Fuel) thermal spraying. Amorphous alloy powders produced by using gas atomization were used for HVAF thermal spraying to produce an amorphous metallic coating. Microstructural investigation showed that crystallization and oxidation occurred during thermal s...

A spray track was designed and built to conduct replicated laboratory and field studies to compare different nozzle configurations on the ability of each to achieve lower canopy spray coverage. The purpose was to determine which nozzles might be more affective in preventing or controlling Asian Soybean Rust. Twenty nozzle types were compared in the lab and twelve nozzle types were compared in t...
