Multiscale 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...
متن کاملModeling and control of HVOF thermal spray processing of WC–Co coatings
This work focuses on the modeling and feedback control of the high velocity oxygen fuel (HVOF) thermal spray processing of WC–Co coatings. A first-principles-based process model is proposed to explore the fluid dynamics and particle inflight behavior in the HVOF flow field. Rule-based stochastic simulation, which encapsulates the main features involved in the deposition process, is used to capt...
متن کاملThermal 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 کاملFailure Mechanisms Investigation in Thermal Barrier Coatings under Isothermal and Non-sothermal Fatigue Loadings using Design of Experiments
In this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. In this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...
متن کاملCharacterization of hydroxyapatiteynano-zirconia composite coatings deposited by high velocity oxy-fuel (HVOF) spray process
Hydroxyapatite (HA)ynano-zirconia composite coatings were successfully produced through high velocity oxy-fuel (HVOF) spraying of radio frequency (RF) plasma synthesized powders. Microstructure characterization and morphology analysis on the nano-structured coatings were conducted using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffractometry (XRD), and d...
