Thermal Spray Coatings
THERMAL SPRAY is a generic term for a group of processes in which metallic, ceramic, cermet, and some polymeric materials in the form of powder, wire, or rod are fed to a torch or gun with which they are heated to near or somewhat above their melting point. The resulting molten or nearly molten droplets of material are accelerated in a gas stream and projected against the surface to be coated (...
متن کاملVision-aided Monitoring & Control of Thermal Spray, Spray
Vision is one of the most powerful forms of non-contact sensing for monitoring and control of manufactusang processes. However, processes involving an arc plasma or flame such as welding or thermal spraying pose particularly challenging problems to conventional vision sensing and processing techniques. The arc or plasma is not typically limited to a single spectral region and thus cannot be eas...
متن کاملRecent advancements in Thermal Spray Coatings
Within most industry segments, significant financial losses may be incurred due to accelerated wear of various components. In order to minimize the effects of mechanical wear and extend product life, thermal spray coating solutions introduced into production and is further developing them to meet even more demanding wear applications. Applying coatings using thermal spray is an established indu...
متن کاملNumerical modelling of thermal spray systems
The purpose of this paper is to present a brief overview of the MD* thermal spray process, review the current existing models of heat transfer and fluid mechanics relevant to this process, outline a simplified thermal model implemented together with the results, and discuss the activities required for the implementation and verification of an accurate temperature model of the MD* thermal spray ...
متن کاملMultiscale Modeling of Hvof Thermal Spray Process
The major physicochemical processes involved in an industrial HVOF thermal spray process (Diamond Jet hybrid gun, Sulzer Metco, Westbury, NY) are studied by a comprehensive multiscale model. The model includes continuum type differential equations that describe the dynamics of gas phase and particles of different sizes, and a rule-based stochastic simulator that predicts the evolution of coatin...
