Spray Characteristics and Droplet Size Distributions From Low Pressure Spray Atomisation

An understanding of the physical mechanisms underlying the atomization process from a spray device can reveal important information leading to more effective device design. A commercial nasal spray device exhibiting low pressure atomization was tested to obtain spray formation, its characteristics, droplet size distribution, and droplet velocity. High speed laser photography combined with an in...

Piezospectroscopic measurements capturing the evolution of plasma spray-coating stresses with substrate loads.

Plasma-spray coatings have a unique microstructure composed of various types of microcracks and weakly bonded interfaces which dictate their nonlinear mechanical properties. The intrinsic photo-luminescence (PL) characteristics of alpha-alumina (α-Al2O3) within these coatings offer a diagnostic functionality, enabling these properties to be probed experimentally at the microscale, under substra...

A low-cost laser scanning solution for flexible robotic cells: spray coating

In this paper, an adaptive and low-cost robotic coating platform for small production series is presented. This new platform presents a flexible architecture that enables fast/automatic system adaptive behaviour without human intervention. The concept is based on contactless technology, using artificial vision and laser scanning to identify and characterize different workpieces travelling on a ...

Low-pressure CVD and Plasma- Enhanced CVD

LPCVD is a process used in the manufacturing of the deposition of thin films on semiconductors usually ranging from a few nanometers to many micrometers. LPCVD is used to deposit a wide range of possible film compositions with good conformal step coverage. These films include a variety of materials including polysilicon for gate contacts, thick oxides used for isolation, doped oxides for global...
