PhD Thesis in Industrial Dip-Coating Process Study with Complex Shapes and Non-Newtonian Fluids

Context

Dip-coating processes involve covering an object with a thin layer of liquid using sequences of immersion in a bath and removal at well-chosen speeds and trajectories. Layer thickness control depends heavily on previous steps, as well as fluid rheology, which in turn affects end-use target properties. Lost-foam casting, a foundry method used in last-generation engines, includes such coating techniques.

Goals and Planning

The main goal of this PhD thesis is to understand, predict, and tune final deposited thicknesses on arbitrarily complex geometries by playing on bath rheology and object removal trajectories and speeds. An experimental and theoretical approach will be used to apprehend all unitary mechanisms and instabilities at play when an object is covered by yield stress fluids and when it is simply immersed and removed from it by translation movement.

Methodology

Experimental device will consist of a laboratory-scale robot arm able to perform complex bath removal moves. Layer thickness measurements will be performed using local laser distance sensors for optimal precision, as well as on-board cameras for global kinetics, dripping, and flow characterizations. Layers flow modeling will be implemented in a numerical simulation code.

Industrial Application

This project will take place in the Center for Material Forming (Cemef) of Ecole des Mines de Paris – PSL University. Many stays and interactions are planned with Stellantis, the project industrial partner. The candidate will be part of Cemef Computing and Fluids research team.
