| 20100098845 | Method for feeding particles of a coating material into a thermal spraying process - In a method particles are delivered to a thermal spraying process for forming a layer on a component. They are entrained there by a carrier gas stream and deposited on a component to be coated. The particles are dispersed in a liquid or solid additive before being introduced into a supply line which issues into the thermal spraying apparatus, the additive, after leaving the supply line, being transferred into the gaseous state in the carrier gas stream. A liquid additive evaporates or a solid additive is sublimated, whereby the particles in the carrier gas stream are separated. The dispersal of the particles in the additive simplifies an exact metering and prevents the particles from forming lumps, so that improved layers can be deposited by virtue of an improved homogeneity of the carrier gas stream. As the additive has been transferred into the gaseous state, it is not deposited in the layer. | 04-22-2010 |

When the valve is opened and the interior of the purge line is evacuated prior to the film forming process, the carrier gas supply unit supplies a carrier gas so that the viscous force acting on particles by the carrier gas is greater than the viscous force in the film forming process. | 06-03-2010 |
| 20100151124 | Cold gas dynamic spray apparatus, system and method - A system for cold gas dynamic spraying of particulate material has a de Laval nozzle and two or more radial particle inlets located between the throat and the outlet of the nozzle, the two or more particle inlets arranged symmetrically around a linear flow path of the nozzle. Blocking of the inlets is reduced by controlling pressure of particle carrier gas to provide a stable particulate material injection pressure before and during introduction of working gas into the nozzle, and/or by clearing the particle inlets of residual particles after a spraying process. Such a system and associated method combines benefits of both downstream and upstream cold gas spray systems. Further, a nozzle for spraying particulate material having a cross-sectional shape that is narrower in a middle section compared to edge sections provides coatings with superior cross-sectional profiles. | 06-17-2010 |
