ullite is widely used as a structural material for applications like thermal and environmental barriers coatings. For some of these applications, hermal spray is a suitable technique due to its fast production time and versatility. This makes mullite a very interesting coating material for thermal pray industry. In the present work, the viability to produce coatings by thermal spray using mulli...

OBJECTIVE An evaluation and comparison is made of the thermal increment at different implant surfaces during irradiation with CO2 and ErCr:YSGG lasers. STUDY DESIGN Five threaded and impacted implants with four types of surfaces were inserted in an adult pig rib: two implants with a hydroxyapatite surface (HA) (impacted and threaded, respectively), a machined titanium surface implant (TI mach...

This work explores the use of both spray drying and d-glucosamine HCl (GLU) as a hydrophilic carrier to improve the dissolution rate of piroxicam (PXM) whilst investigating the electrostatic charges associated with the spray drying process. Spray dried PXM:GLU solid dispersions were prepared and characterised (XRPD, DSC, SEM). Dissolution and triboelectric charging were also conducted. The resu...

Spray atomization is a common process found in different industries, where sprays under high injection pressure are widely recorded in the literature. Nonetheless, research on spray breakup mechanism under low pressure in pharmaceutical industry is still relatively rare. Numerical model in the Lagrangian approach was modified for simulating the spray formation from a nasal spray device in the c...

Thermal spray processes found wide applications in many industries, including the automotive industry due to their versatility and efficiency. There were a lot of publications about hard-facing these components using some thermal processes: electric arc wire, High Velocity Oxygen - Fuel (HVOF), detonation, plasma. The decision engineer depends on context based specific character component, oper...

This study investigates a new concept of producing precipitated calcium carbonate (PCC) from steelmaking slag and carbon dioxide via a spray carbonation process. The presented laboratory-scale spray carbonation test reactor uses a spray nozzle to disperse fine droplets of a Ca-rich solution into a spray tower, where calcium carbonate precipitates as a result of the reaction between calcium and ...

Abstract The integrity and properties of ceramic coatings produced by atmospheric plasma spraying are highly controlled the splat morphology interconnection. In this study, influence selected parameters (spray angle, surface velocity spray gun, substrate temperature) on coating microstructure was investigated. A favorite set gun parameters, which their effects have been verified previous experi...
