Abstract
Sonic technology means the technology where the sonic devices are used and where the intensification of the heat and mass transfer is obtained owing to the pressure or flow capacity oscillations, introduced in the technological flux. This paper consists in the examination of the practical application results of the various technical systems with sonic injectors.

Coatings Systems: Chromium Carbide, Nitride and Carbonitride
The process of the chemical deposition from vaporous implies the adsorption of the mobile atoms (monomers) on the substrate surface, their migration with embryos and stable nucleus formation, followed up by further growt...
The Structural Design Improvement of a Twin-Hull Ship
The paper is focused on the strength analysis of the structure of twin-hull ships, particularly a passenger catamaran. Catamarans have some advantages against conventional monohulls: larger deck area and cargo volume, be...
Effect of ZnO Nanoparticles on the Anticorrosion Properties of Epoxy Coating
Homogeneous epoxy coating obtained by embedding ZnO nanoparticles (≤50 nm) in the epoxy matrix, was applied on Grade A naval steel substrates by dipcoating method. The morphology and microstructure of the coatings were c...
