Deformation and solidification of molten particles on a substrate in thermal plasma spraying
In the present study, the flattening and simultaneous solidification of a liquid droplet upon its impingement onto a solid surface has been numerically simulated and an extensive set of results has been generated to represent ...
Numerical simulation of the spreading and solidification of a droplet in plasma spray process
and low Stefan numbers. We found a good agreement betweenour results and the available data.
Conclusions: The simultaneous solidification has an important effect on the impingement process in plasma spraying such that the two phenomena...
Effect of substrate properties on the formation of plasma sprayed alumina splats
The effect of substrate characteristics on the formation of plasma-sprayed alumina splats was studied using both experiments and numerical simulation. Knowledge of the particle and substrate conditions is critical in understanding coating formation...
Modeling of DC plasma spraying operation including particle impaction and solidification
In this paper a complete model of a DC Plasma Spraying system is presented. The model consists of three parts: a) Calculation of the flow and the temperature field in the plasma. The plasma system uses a shrouding gas. A boundary fitted coordinate...
Dynamics of splat formation in plasma spray coating process
The paper describes recent developments in modeling formation of plasma spray coatings. Specific attention is paid to the three-dimensional simulation of droplet impact and solidification under plasma spraying conditions. It is shown that the extent...
On the spreading and solidification of molten particles in a plasma spray process: effect of thermal contact resistance
The spreading and simultaneous solidification of a liquid droplet upon its impingement onto a substrate permitting thermal contact resistance has been numerically simulated; the effect of contact resistance and the importance ...
Enthalpy method on modeling droplet impact and solidification in a plasma spray process
A complete mathematical formulation has been developed to numerically solve the fluid dynamics, simultaneous solidification and heat transfer phenomena associated with a droplet impacting a fixed
substrate in a typical thermal plasma spray...
Influence of plasma spraying parameters on properties of thermal barrier coatings
Thermal Cyclic Fatigue Behavior of Nanostructured YSZ/NiCrAlY Compositionally Graded Thermal Barrier Coatings
In this research, thermal cyclic fatigue -TCF- behavior of a compositionally graded
layer -CGL- nanostructured coating was investigated and compared with the TCF
behavior of a micro-CGL coating. The layers, as a ...
